Description

Built as a powerful backyard plinker and small pest eliminator, the Diana 350 represents the brands affinity for producing quality spring-piston powerplants.

From its streamlined Monte Carlo beechwood stock to its adjustable 2-stage T06 trigger, the Diana Magnum 350 is ready to up your game on the backyard range. Available in .177 and .22, this springer can send rounds at speeds from 1,000 to 1,250 fps with enough power to bag small game at long range.

Each Diana 350 Magnum can shoot right out of the box with its included adjustable rear sights. If you prefer a scope, the 350 includes an 11mm Dovetail to zero in on paper and prey alike. Sporting the famed Diana T06 2-stage adjustable trigger, you can adjust for the pull weight, the length of the first stage and the sear engagement.

If you love the straightforward power of a spring-piston breakbarrel, the Diana 350 Magnum will not disappoint­—don’t be without it on your next plinking session.

Overall an excellent rifle. Had my 350 .22 for around 5 yrs now. A big rifle at 48 inches but not heavy for this length. Incredible hunting springer, would give it #1 for this and I have almost countless springers. Around 20k pellets through the gun and not one problem other than power dropping at around 5k shots. Custom tune fixed this and better than new with thousands of more pellets fired.

Nothing other than a hair deeper stop hole on the scope rail, would make it easier to fully engage the stop pin.

Take your time mounting up your scope. GOOD MOUNTS. Sportsmatch, UTG Pro (my first choice as it's easy to fully engage the stop pin) or RWS Lockdown one piece. I know guys who have put the scope on quickly, not securely and this leads to issues. One final comment is I gave it a 4 for accuracy only because my tx200 .177 is more accurate. For a mag springer in .22 it is a HIGHLY accurate rifle.

Nice stock, well made rifle. It is an adult rifle for sure.

First shots in my yard were a little loud. I'm going to the range to finish sighting it in. Slightly heavy but it is an adult rifle.

Everything went excellent with ordering. Got exactly what I wanted with quick shipping to Alaska.

Just received mine. Fast shipping and generous company. I received a PCP air rifle along with my order. Two air rifles for the price of one! Oh well, return shipping label printed for the PCP. I also purchased a scope so I need range time to sight it in. I tried it in the yard and expect the police to come by soon to see what the shooting going on was. It sounded like a .22 LR going off on my end so I stopped the sighting in and will visit the local range. Hopefully it will quiet down after break in. This is an adult rifle! Has mass and length on the large size but very little recoil so we will see. Looks well made, beautiful stock and a quality rifle. As soon as I get some serious range time in, I'll try to add to this. I was trying about 20 yards and did notice that the 3/8" plywood wasn't much of a back stop. This should be a serious small game gun.

Nothing I can see.

My order went effeciently. Packing and shipment went quick, and I had it in my hands in Alaska in a week. That's pretty good for here.

It won't quiet down after break-in. Your pellets are breaking the sound barrier, that's what the "crack" is. Speed of sound at sea level is 1125fps. My 350 exceeds 1125fps with most lighter pellets. Shoot heavier pellets and it will quiet down.

I like the trigger it is touchy and I like the overall quality of the product.

Nothing.

It does require effort to ready the gun to shoot it has a strong spring.

First off the exercise its a work out also the noise it makes also the weigh of rifle and the stock checkering.

First and foremost I would change the trigger reason why it has three screws that you need to adjust after trial and error you could very much literally screw it up so to speak. The gun is great just need an easier way to set the trigger. I bought a refurbished in The condition was good the stock had some dings the rear sight was broken but pyramid air totally replace the rear side they’re really great to deal with other than that it’s all good. I bought the refurbished because absolutely nothing was available so I got my 22 caliber also have a 177 caliber love them both.

What customer should know well you better have some muscles you better make sure when you caulk that all the way down that its locked down the trigger you wouldnt want that barrel getting away from you so I could be just as deadly as a back alley fight. When I first got mine caulking at all kinds of weird crunchy sounds was coming out after 50 or so shots its seem that I may have been getting used to the noise or it was leaving the gun. But now that I have a couple hundred shots through it its not easier to Coch but it does make no noise now I think the spring had to find us home. Other than that its a great rifle if you like Diana I do its a different craftsmanship than HW-80

It’s elegance balance in ultra power for a Springer,

Most important thing I would change is the safety it needs to be made out of metal Im so paranoid of it breaking why they chose plastic on such an important piece is beyond my thought process all I can say is achtung

Its a long rifle it has a long compression stroke with a very powerful spring its not for the week its not for the mw its so powerful if you dont pull out down all the way that barrel come out and club you in the face and knock you out, thats what you’re paying for power so they have our power you have to have power to be able to keep it safe not only in shooting technique mostly and handling technique because that thing I’ll club you to death if you let it that’s what you should be safe know safety first

Accuracy of RWS Diana Quality of there guns

RWS Diana are some of the finest quality air guns
German standards & engineering I have had them for 30 plus years and unfortunately had to replace
My favorite one due to theft but replaced with the
Diana 350 magnum.177 for the last 22 years I just added the Diana 350 magnum.22 same accuracy just a little more nock down power. I would never buy anything but theses guns well that is if you are serious about varmint&bird depredation control.
I have had other guns but the accuracy just is not there and when you only get one shot it needs to count. I would also recommend using a heavier pellet as this increase accuracy and nock down power

A beautiful rifle ...the finnish is supurb..very accurate easy to cock and good power for .22'break barrel

the fixed sights broke shorty after I bought it front blade would not stay up I have no idea what size I need to replace it I kinda got it rigged with putty as I like shooting this gun with open sights ...still very accurate.....I have also had a holo reflex sight on it

for small game it is great up to maybe rabbit
anything largee .I can't put down
have used it in raccoon and possum but lost them ...I have tired it on coyote numerous times at close range with head shots ...no luck

it is a gun you can shoot all day long with great fun

Chris Nov 23, 2021

A .22 caliber break barrel springer/gas piston/PCP air rifle is fine to use for squirrel and maybe rabbit, at the most, to achieve an ethical "one shot, one kill". To use it on anything bigger requires the use of a traditional firearm to make a humane kill. Otherwise, you are maiming/wounding the animal and that is unethical.
