This pellet rifle is so fun to shoot. It's very accurate too. I have breakbarrel pellet rifles for pesting, this one is just for fun. Perfect for indoor shooting during the covid era.

Nothing.

Get an extra mag, you will be glad you did. I also got a 12 gram co2 adapter so that I can run some lubricated co2 through the gun occasionally.

For the cost of this Rifle I was impressed with the accuracy. I added a inexpensive red dot and had .75" groups at 20 yards. Lots of fun to shoot and drew a lot of intrest from my shooting buddies trying to figure out what I was shooting.

Lower weight, gun is fairly heavy when you add 80gr tank and loaded magazine. Also I would ship with extra mags or at least additional ammo belts.

Seems to shoot better with copper plated pellets. Extra mags are avaiable online and come with 3 belts.

Excellent quality training gun. accepts most of my AR accessories and feels right in your hands

The looks, real feeel

It's a little heavy. I wish I would have got the shorter version for transport purposes.

By 1 if it's in your budget

This gun feels awesome the only cons is that its heavy and the price besides that overall great gun great craftsmanship.

The price

The co2 is rediculiously expensive

I bought this rifle about 1-2 years ago and have loved it so far. I've only been having trouble with the magazine because they sometimes won't turn and they'll get jammed and it wont fire. And would also love if they made a handguard for it just like the PCP version, With M-LOK and a QD mount because keymod is just out dated and not as reliable as M-LOK and there is more accessories out there for M-Lok so if SIG would make a new hanguard for it I think every SIG airgun owner would purchase one.

Bought this a while ago and have had some nice shots with it. I am experiencing a little problem now as the co2 bottle will not seal anymore and as a result, I have wasted 3 bottles of co2.

30 round belt, which is the main reason why I finally convinced myself to pay so much for a CO2-powered zinc diecast gun. And there's an HPA adapter so I can go regulated & avoid the temperamental character of CO2. Storage inside the grip for the loading tool, even though it seems to be missing a foam insert to keep that tool from rattling around. 3" groups @ 50 yards on a rest, using FTT Green pellets, dot sight & tuned trigger

Trigger could be wider, to deal with that stiff pull. Fore-grip could be more ergonomic - rear of the grip has sharp corners that will dig into your hand. The sear holding the hammer needs to be shaped so that it does not drive the hammer back into the mainspring just before firing - this & polishing will greatly reduce the trigger pull. Bit more grease inside - there's a few places that didn't get grease and improved the action feel after I added some. Shorten the barrel an inch to have one single baffle inside the can, or have a version that simply uses the MPX barrel with full baffles? And the battle sights are really just that, not very good for precise target shooting. The sight picture is too blurry. I put on a TRS-20 dot sight & groups instantly shrunk

You can not have the CO2 or HPA still attached & pressurized when taking the gun apart, the body halves are also holding the tank block together. The bottle threads are in a separate collar piece that is not directly attached to the inlet body where the bottle seal is - so taking the gun apart will automatically dump your bottle, as I found doing it the 'fun way'! Re-shaping the sear so the contact surface where the hammer rests is curved to follow the sears axis is the number one thing to do in order to fix the really bad trigger pull. The sear & hammer are made of really soft pot metal, so I wouldn't expect these parts to last long without changing their geometries. I only had about 15 belts through the gun when I tore it apart & found that the hammer was already wearing down where it contacts the sear. If it wasn't for how the outside of the MCX/MPX simulate real iron, then this is a very over-priced toy that won't last. If you try hard enough, the suppressor does unscrew

As far as looks go, this thing is the real deal. Ive only had one opportunity to test it out, and it performed perfectly. I need more time to test it out in other situations, but otherwise itsawsome. Its so good that I ordered the Sig MPX. Thank you Sig Sauer, and thank you Pyramyd Air as well. Very satisfied.

As of right now, nothing at all.

Yes, make sure to use only pellets that fit the rotary belt- longer pellets, like Crosman Gold Flight Penetrators will be too long and jam the gun.

Honestly I had so much fun the first two days of using it. But the second CO2 I entered in the pellet gun, the Air from the CO2 starting spraying out of the barrel. And it keeps doing it over and over with each CO2 cartridge. I was extremely happy until this happened now I can barely use it.

I bought my .177 MCX in January and although I haven't had too much chance to use it, when I did it was what I'd expected. Fun. I chose this rifle to train my nephews and get them outdoors and off the xbox. Hopefully it'll do the trick. Spare magazines are hard to get hold of in Cyprus and expensive compared to US prices.

I liked the realism and quality of sig sauer products. The unit has a fair amount of power and the co2 is easy to install with no wasted gas. The open sites are nice!!! But i was never able to tune them in were i wanted could be just me! But i purchased a scope and all is great! I also tried the conversion kit to convert to a precharged and that didnt work eitther, it made the rifle too long for my short arms.

Would love to see a nitrogen capsule or something stable so that it can be taken out in the cold

Sig sauer is resl good

I love how it looks, feels and performs. It's just a mean-looking pellet rifle. It shoots very accurately, and the suppressor on the front really works well as this gun is very very quiet. You get a lot of shots from a single large Co2 bulb, at least 200.

Less Plastic and more metal adding to the weight would have been nice. Especially the clip. There is just too much plastic on this rifle.

It's a great gun and worth every penny in my opinion. Just don't take it outside or you more than likely won't live to tell your tale.

Had mine for 18 months and its spent most of its time in the shop for repair . Seemßo have reacoring problem with the cylinder seal

Received my rifle yesterday,No matter what i do it only shoots single bullets.Have to cock the handle between every shot.For a semiauto this is rubbish….Looks are great though ;-)

Fairly accurate

Make it cost less because it's not going to last

I've owned 1 for around a year great at first. Reloading sucks but really no other way. Fps is way less than advertised. I bought the air venturi 13 ci tank and adapter aired up the tank installed the adapter to the gun and blew all the air out. Took tank back off and had a blown o ring. Found a burr in the adapter got it cleaned up and worked, tho it only gave me around 280 fps. Got it out the next day and filled the tank up again and blew another o ring. Went to go back to co2 and it all dumped out inside the gun.

Everything about this air rifle is great minus the FPS, I bought this to shoot small mice and rats. Choose this model for the 700 FPS as advertised, im Hoping I can return it tomorrow but we will see what my local firearm store has to say about that.

this air rifle worked for about 3 weeks of very light use. now it wont shoot at all. just stopped working.

I’ve waited to post a review to see if the quality out of the box would carry through, short answer is YES, go buy one! Longer explanation, i’ve owned my SIG now for one year and it’s been a solid out of the box, and a pleasure to shoot. I have no issues with my SIG with regards to CO2 tanks/seals or jams with loading. Very accurate and a ton of fun to target shoot in the woods.

Bought this as it states it would deliver up to 700fps. Had mine tested on the weekend by Welsh Willy and mine shoots between 360 and 400fps with a range of different pellets!! What an absolute load of rubbish. If you want to buy this for looks please do, but that is about as far as it will shoot. Taking mine back today for a refund, not fit for the purpose it was bought for. Very annoyed to say the least.
