  • Summary

I hadn’t planned to write about the Umarex Synergis underlever repeater today but another gun I’m testing had a problem and I had to stop the test. I’ll tell you about that when I resume testing the gun, but today we start a report that several of you have specifically asked for — with my brother-in-law, Bob, being the first and also the most persistent.

Yes I’m aware that the rifle isn’t quite on the market as this is published, but it should be soon. This is one of the rare times that I will get ahead of distribution a little.

Underlever spring gun repeater?

The Synergis is not the first repeating spring-piston air rifle with an underlever. That would be the Haenel model V that I reported on back in 2009. What makes the Synergis different is, number one — it works. Repeating spring-piston rifles have only recently been reliable. The second big difference is the Synergis has a gas piston.

Repeating spring rifles are a very hot new concept, though they have been around for many decades. Today’s crop of shooters wants a repeater, even in the spring-piston rifles, and several companies have stepped up to give them exactly that.

The rifle

The Synergis I’m testing is a 12-shot .177-caliber repeater. You cock it with the underlever each time you shoot and that also loads a pellet from the rotary magazine.

The rifle is 45-3/4-inches long, but the black synthetic stock has a very slim forearm that allows the rifle to sit low and comfortably in the off hand. The pistol grip is also quite slender, giving the rifle a very nice overall feel!

The stock is rough over the entire surface, with more aggressive roughness on the forearm and pistol grip. It’s a hard material, but it is not a bit slick in the hand. It seems good for all types of weather. The rubber butt pad is firm but not hard. It sticks to your clothing and will prevent the rifle from slipping.

The undelever has a wide synthetic handle that is pulled back to release the lever, I find it easy to pull back and still very secure when it’s locked forward. In fact, it took a moment for me to figure out how to release the lever. I have to give the designers credit for a smooth transition at the handle.

Umarex Synergis underlever
The underlever handle is spring-loaded to lock up tight, yet remove for cocking easily.

The rifle I’m testing weighs 8 lbs. 7 oz. That, plus the length and the cocking effort that I will measure in Part 2 give us a rifle that’s made for adults. I find it large but not a bit bulky or overpowering. The pull is 14-inches on the nose.

Magazine

The rifle comes with 2 magazines. For a powerful air rifle at this price point I find that a welcome surprise. The magazines are the spring-loaded circular style that have become very popular in recent years. I have loaded one of the two magazines a couple times and so far they seem very reliable.

Sights

There are no open sights but the rifle does come with a 3-9X32 scope that I will also report on. And the Synergis has a long Picatinny rail that will accept either Weaver or Picatinny scope rings. This type of base is fast becoming the norm for spring-piston rifles as it solves the scope stop problem at the same time. Also, this base is controlled by a specification, where the older 11mm dovetails are not and vary widely in width plus both the depth and angle of the cuts.

Umarex Synergis scoped
The Synergis comes with a Picatinny rail scope base and a 3-9X32 scope and rings top go on it.

Fully shrouded barrel

The barrel is fully shrouded. That keeps the discharge sound low, but the shooter will hear the powerplant through the bones in his skull that touches the stock, so to him only it will sounds louder. The barrel appears to be 18-1/2-inches long, but the shroud conceals the final 2-inches of space that’s ahead of the true barrel.

Trigger and safety

First of all, can we have a round of applause for Umarex? The safety is entirely manual. You decide when to put it on or not. That couples with the repeating function to make this rifle cycle between shots fast.

And the trigger? Let me just say, “Kowabunga!” And, it’s a good kowabunga. The trigger is not adjustable, but try a few shots and tell me whether you think it needs to be. Better yet, let me measure it in Part 2 and get back to you. I don’t think you’re going to believe it. I test airguns all the time and I don’t believe it!

The Pyramyd Air website says the trigger is 2-stage, but this one certainly seems like a single-stage . It may just take some time to break in before stage one can be detected. Anyhow — kowabunga!

Cocking effort

Because the Synergis has a gas piston the question arises about how hard it is to cock. I have to say that the gas pistons and gas spring guns (spring is compressed gas but the piston is a separate unit) I’m seeing this year are quite advanced in this area. Even those that are less expensive are cocking easily.

Having said that, I want you to know everything. A coiled steel mainspring starts compressing in the cocking stroke with less effort and builds to the maximum. A gas spring starts at the maximum effort and stays pretty constant throughout the cocking stroke. So a gas spring always feels heavier than it is. If a coiled steel spring gun is set up correctly the maximum effort is reached at the point that the cocking stroke becomes the most efficient and cocking feels lighter than it is. I tried the Synergis at the 2019 SHOT Show and was surprised by how easy it is to cock for the power. Now that I have a production rifle to test I am still surprised.

Accuracy

We find out about accuracy in Part 3, so there is nothing to tell you yet except for one thing. In the box with the rifle Umarex also sent me a tin of JSB Exact 8.44-grain domed pellets. I’m no detective but I have a sneaking suspicion that Umarex wants me to try them in this rifle. What the heck?

One thing I want to dispel is that fixed-barrel spring rifles like this one are no more accurate than breakbarrels that are designed and built right. The stationary barrel adds nothing to the accuracy equation — nor does it take anything away.

Feeding

However, the Synergis also has a rotary magazine. So, how does that work in conjunction with the barrel? In short — are the pellets pushed into the breech by a probe or are they just blown in by a blast of air? Well I took a “thousand-word picture,” just to show you.

Umarex Synergis probe
And now you know. The bolt probe is hollow for air transfer and it is a probe to push the pellet from the magazine into the breech.

Summary

The Synergis from Umarex brings us some new technology and a reliable fixed-barrel repeating capability that is very desirable and hasn’t been seen before. The price is good, so let’s hope that its accurate!

    Bully for Umarex to make such an interesting rifle! Lets hope the scope is worthy?
    So with this set-up I assume that the bolt probe to pellet skirt interface is the crucial area.
    Wonder if it works well with lots of different pellet skirt types?
    Looking forward to #2!

    How long is the gun? Don’t see it listed anywhere.

    If it turns out to be as accurate as my Gauntlet is I say it’s going to be a winner.

    And how about that. No open glowy sights.


  3. B.B.,

    Very nice and very interesting. Well done on getting a very sleek/stylish looking design too. There is much to like. The only thing that hit me was no cheek riser adjustment. For the price point,.. I guess not. They did not skimp on the metal at 8 # 7 oz.. I would have guessed less by appearance. That is pretty heavy though.

    Very much looking forwards to the accuracy test. The blow into breech causes me pause.

    Good Day to you and to all,……. Chris


    • Chris,

      The Gamo CFX had a very long transfer port such as this, but were quite capable air rifles. It is true that long transfer ports do rob some of the power, but as long as you are not expecting uber magnum power, this should be fine.


      • RR,

        I was thinking more in the area of any magazine/chamber misalignment to the barrel and the inherent loss of air if the front of the magazine is not sealed to the breech,…. as in the revolvers that are under rearward spring pressure for the barrel.

        Unless,… the transfer port/probe pushes the pellet all the way into the breech when the underlever is latched??? In that case,.. it is no worse than any other magazine gun.

        Chris


        • Chris,

          It does indeed come all the way forward into the breech and seals it. Also, if your pellet head is large enough to engage the rifling, the shape of the end of the probe will help “repair” thin skirts that have been damaged by the magazine.



          • RR,

            Upon review of the article,…. BB (did) mention in the caption under the picture of the probe that the probe (in fact) pushes the pellet into the breech of the barrel. Duh! 🙁

            Chris

            Word of warning,…. work just went from four 10’s to five 10’s plus 8 on Sat.,…. (indefinitely). My “duh” moments are likely to be more frequent! 🙂

            Chris


    • Chris,

      I was noting the weight as well. Don’t think that you can get away from it with underlevers – the cocking bar is like a second barrel and that’s a fair chunk of steel. As you know, the TX200 is a hefty rifle as well.

      Think that most of my rifles (scoped) are around the 9 pound mark – which is ok but is probably the main reason I like to grab my Maximus when I go for a walk-about, it’s so nice and light.

      Hank


      • Same with my Gamo Urban. It nice and light, and short as well. Very easy to carry by the pistol grip with the muzzle pointing down and not scrubbing on the ground. I like short and compact rifles.


  4. BB,

    It appears this has a sliding compression chamber with the pellet probe/transfer port permanently attached to it and the barrel assembly and transfer port also appear to be centered. Is this how you see things?

    I am impressed so far. It reminds me so much of my old Gamo CFX. It looks as if Umarex took the TX200, the CFX and the Dominator, mixed them together and did it up right. I know it likely will be, but I do hope it is not too hold sensitive. The weight may help that issue. We shall see.

    Does this air rifle have a long stroke? I do hope so. I abhor those short stroked, snappy sproingers.

    I most definitely wish to hear more about the trigger. As you said the description says it is two stage. Either one or two stage I could care less as long as it has a nice, clean break. Most of my airguns are single stage. I do not notice any travel in them. I can shake and bounce them all I want and they do not go off, but when I apply pressure to the trigger they break cleanly. Some may take more force than others, but I know exactly when it is going off.

    Now as for my two stage triggered airguns, they are a trigger snob’s dream come true. 😉

    Umarex may have finally “got it right”. I just hope their Chinese manufacturer understands strict quality control and will maintain such. If it is the same company, they seem to be doing well with the Gauntlet.


  5. B.B.,
    I’ve been looking forward to this report, B.B.! I hope the Synergis (any comments on the futuristic name?) is a good performer. It has good looks, interesting features and a low price. If it handles well and is accurate, Umerex may have to make a real lot of these… A problem with fun repeaters though, they make my pellet tins get empty real fast!

    How do I get a picture of my modded B3 wooden stock to Hank (Vana2) for his perusal? It is pretty goofy, some will like it, some may not.

    Have a great day, all!
    Will


  6. B.B.,
    Thanks for allowing me to post this, I had broken it at a weak spot I created at the wrist and got good repair advice here on this blog. Two long screws and epoxy hold it together. It makes me grin and it shoots OK! I like the little hollow for the trigger thumb in the grip, too bad you can’t see it! The goofy paint job keeps things from getting too serious. This is a start toward making my own stock, I’ve been collecting wood!



    • Will,

      Well done Sir! I like your fun and light hearted approach to the project. Yup,…. ain’t it funny how we can take it all to seriously and often need the reminder to keep it fun? Been there, done that,…. and probably prone to repeating it,……. 😉

      Chris


  7. There’s a saying I’ve heard designers use that goes something like “If it looks right, it is right”.
    Looks way better than that hincky looking mechanism on the other price point gun that repeats.
    This one might get my pocket money.
    Roberto


  8. B.B.,

    The magazine is a proven design for PCPs, but dry-firing isn’t damaging to a PCP. A reviewer of the Synergis on P.A.’s page for the air rifle points out that a shooter who loses count risks a dry-fired shot #13.

  9. Gunfun,
    Thanks for your kind appraisal! Regarding the paint, it was sprayed with (the wrong color) blue Krylon rattle can gloss, then the white and the shark mouth were done with artist’s acrylics, then the whole thing was sprayed with Krylon clear satin finish.


    • Will S.
      Nice. I have used Krylon spray can for years on alot of things but never wood that I can remember anyway. Usually metal or plastic.

      Did you have to put any primer sealer on the wood before you sprayed the colors? I know wood usually soaks up the paint before it starts covering.

      I fly rc planes. Back when I was young some of the old timers use to paint their planes. I used the shrink on Monokote plastic covering. It was kind of cool seeing some of the paint schemes they came up with. I was always a fan of the P40 Warhawks. Your shark paint job reminded me of those planes.




  10. GF
    You have mentioned planes here in the past. I do, too…since the eighties and some of the old-timers (now us!) used to paint theirs. And Monokote is how I cover mine, too.
    So the wood of the B3 gun had to be sanded smooth, holes ‘n dings filled, primed, sanded, refilled, reprimed, sanded with 220 grit and all that happy happy process. I have a sneaky feeling you have something planned. What kind of project are you brewing up, GF?


    • Will S.
      Project. Nothing painting wood right now anyway. But I have thought about painting my Sig MPX. Especially the HPA regulated bottle and adapter. I got the Earth colored Sig. So I would like to match the bottle and adapter to the rest of the gun if I can get the right color.

      And kind of thought that’s what you went through prepping your gun to get it ready to paint.

      And I think what always kept me going with the Monokote on my planes was the transperent colors they have instead of painting them. I liked the Monokote because it showed off the balsa work building. Plus the plane looked cool setting out in the sun and flying. Oh and did you ever do any tissue covering on any of the small lightweight planes back then where you sprayed them with atomized water to stretch the tissue. I built a bunch of free flight planes like that too back then.



  11. I read about this beauty this morning when I first woke up and was having my morning coffee before getting ready for work. This is my morning routine for many years. Yes, I have been looking forward to this review for a long time as I want a repeater but prefer an under-lever over a break-barrel. I don’t like slapping the barrel to cock the airgun. A PCP would be nice but I just am not ready to purchase all the accessories that are required. This airgun fits all my wants and requirements. Now I am just waiting on a good “report card”. BB mentioned that you cannot adjust the trigger, so I hope it is light as all my firearms are adjusted to 2-3 pounds pull. Just my personal preference.

    Who in blazes came up with the name Synergis???? Spelling it backwards as Sigrenys sounds just as silly. Neither word means anything or is inspiring. Maybe they are playing on the word Synergy which means the creation of a whole that is greater than the simple sum of its parts. Anyway, I’m excited that this nice product is finally available or soon will be. It will surely be on my Christmas list.

  12. BB,

    I also asked about this gun and am excited to see how it does.

    Not long after I mentioned the Synergis here, I received an email from AGD about another Umarex import that is also an under lever. It’s the Browning Leverage and, with the deal they were offering in mid August I was able to get the .22 caliber gun/scope (3-9X40 AO) combo along with 5 tins of pellets ($5-$6 tins) with free shipping for under $165. They actually had the gun combo for 10 or 15 bucks less a few days after I ordered mine but in spite of feeling a little cheated on that count, I’m still thrilled with the gun, so far. With the scope it weighs right at 10 lbs and my wood stock has some nice character on the raised comb and grip. The scope is from China but it is working great for me. I only own inexpensive scopes and they never eliminate parallax by setting them to the distance on the adjustment ring, until this scope. It has been right on the money.

    I’m still getting used to the gun and have just finished testing different pellets at 12 yds in my basement and have found several that are promising. I am also pleased to report that it isn’t very hold sensitive. I’m including a photo of a 5 shot group at 12 yds with Falcons with the gun rested at the end of the cocking slot, right on the bag. ( actually the “bag” is one of those blue, gel-ball-filled, hot/cold compresses that I re-purposed) That’s an Advil tablet next to the group, BTW. The trigger is not that great but it is improving and if it continues on its own or I have to intervene at some point, I expect that good groups will be had without quite as much concentration as is required now.

    If the standards set forth for the Synergis are anything like what this Leverage was built to, I think you’re gonna have a winner on your hands, especially for the price, and you may find me creeping back over to the “light” side.

    Here’s the pics

    Half





    • RR
      I saw that somewhere else and absolutely can’t stand it. The front half anyway. If that was left off and the butt stock left on I would like it. The red colored part is what I’m talking about. Ugly.

      I took the front rail/heat shield off my MPX and like the looks much better now. I’m at work and I don’t have a picture of it that way. I’ll post a picture tomorrow to show what I mean.


      • GF1,

        I understand. I would want the black one.

        The main problem with this thing is it is just way too expensive. For $1300 I can build an awful nice carbine from a P-Rod, TalonP or a Rex.

        I do like the side lever action and clip of the pistol though. I tried to get Jefferson State to build a side lever action for the P-Rod similar to what they did for the M-Rod. I have never liked the Marauder bolt action for some reason. Maybe because it is at the very rear of the action.


        • RR
          Here is the picture of my MPX. As you can see I hav the front removed on it. I was actually thinking about painting the hpa bottle and adapter the same color as the body of the gun. But the black scope, black pistol grip and now the black barrel kind of balance out the colors on the gun. Probably will leave it be.

          And just to throw this out there incase anyone is wondering. Th scope is set on 3 magnification. And when I shoulder the gun I pull both arms onto my ribs and check this out. The HOA bottle rests on top of my shoulder like a Bazooka. I can actually point and shoot pretty quickly and accurately. The scope acts kind of like a low mag dot sight. The line of sight locks in quick to and I have a pretty wide field of view. Works out nice for my both eyes open shooting. Had to bring it up while we was somewhat on the subject. 🙂

          Oh and forgot. Yes would take the Prod or the AirForce gun over the Rex or the dressed up Ataman pistol any day.



            • RR
              Ok I see we need to do some thinking.

              Power. The right amount is good if you know how to use it.

              Remember me saying if a pellet will go through both sides of a aluminum feral can it will take out a starling or sparrow and such. Well the Sig MPX will do that out to about 25 or so yards with a 7 grain wadcutter and remember I’m on HPA so that’s boosting power.

              And on the accuracy side I took out some flying grasshoppers that learned to hover. They was around 20 yards and free hand shots. It took me most of the time to get each one on the 2nd shot.

              And yes obviously not a single shot repeater Prod. But it gets the job done that I use it for. That’s what it’s all about. Oh and the follow up shots no way compare to mag bolt action repeaters. The Sig MPX will blow them away.


              • GF1,

                I understand. Some of the old gals around here would and do shock and surprise folks with their capabilities. What I am saying is it is not for me. What I am wanting is a light carbine to take out bushy tailed tree rats at nominal ranges. I know the P-Rod is up to it and so is the TalonP, AP-16 and Rex. I have even thought of a Maximus or Fortitude and turning them into carbines. Something I could throw in a scabbard on a backpack and hardly know it is there until I need it. The TalonP and Rex would have the advantage of abundant power.




                    • RR
                      Yep I know you know Lloyde. Remember I was involved with him getting the Mrod double going.

                      The first double for the Mrod was mine. And it was even a aluminum tube. So didn’t really add much weight to the gun. But was a big help in shot count since I was making about 70 fpe with my modded .25 Mrod. Good stuff is all I can say.


                    • GF1,

                      He is constantly tinkering. He has a .30 Marauder with a side lever he built. He also has a .51 rifle with dual air reservoirs and a special valve that allows for a real light hammer strike to operate it.

                      We will probably get together sometime this Fall and have a Fun Shoot.



                    • RR
                      Yep me too. Lloyd was the brains behind that one too.

                      Too bad Lloyd can’t give it a go again with his own gun this time around.





            • TT
              For you I’ll get another one and do it up candy apple red. 🙂

              Heck I get that gold pearl base coat on I might just keep it that color. 😉

              And here. I’m going to post a picture of my Walnut left hand stock Tx 200 I got used a short while back. Remember the blueing was scratched. Well this might apall some. But I done this for a reason. If you shoot in the sun you will know what I mean. Especially if you shoot both eyes open. See if you can pick out what I done.


            • Here’s another picture of the wood.

              I can’t capture the picture right but heres another angle of stock and it doesn’t show what I did on the bluing for shooting in the sun..



                • TT
                  I’m happy with the gun all around. The bottom half of the stock has black grain lines too but the exposure erases them.

                  And some one put a magnum tune in it. But it’s still smooth and very accurate. It’s shooting JSB .177 caliber 10.34 pellets at 950fps. It shoots very flat.

                  And what’s getting me is I shoot right handed and it’s a left hand stock. I have no problem shooting it. And it is comfortable to shoot. Surprising as that may be.



                  • GF1,

                    A TX200 Mark III will get up to the 950s with 10.34-grain pellets after about 1,000 -2,000 shots on the new powerplant. They don’t need to be tuned to go that fast — just well broken-in. And they stay as smooth as they were at the start.

                    B.B.


                    • BB
                      My other 2 TX 200’s never shot that fast. One was a .22 caliber so that’s expected. But the .177 never did shoot as fast as this one out of the box. And that’s even with the factory spring in and out of the gun at different times. I actually detuned my .177 TX I had .

                      Either way this .177 Tx is a shooter. As well as the other ones I had. I guess they are just well designed natural good shooters.


                • TT
                  Did you figure out what I did to the bluing on the gun in a specific area to reduce glare when shooting.

                  Here I’ll say now so you can see. I blued the sliding breech that was chrome. It’s black now instead of chrome and shiny.


          • GF1,

            Messed up and sent this to myself.

            He is constantly tinkering. He has a .30 Marauder with a side lever he built. He also has a .51 rifle with dual air reservoirs and a special valve that allows for a real light hammer strike to operate it.

            We will probably get together sometime this Fall and have a Fun Shoot.
