Diana 350 N-TEC Magnum Premium Air Rifle

I purchased the Luxus version the 340 N-Tech, which has a walnut stock and gold-tone trigger. It was and is beautifully crafted with no blemishes or defects save one - the poorly engineered trigger. While others have complained about the cocking force required, it actually is NOT unusual or unacceptable (I say this as a springer devotee).

RWS Diana needs to scrap the hinged steel and plastic rear sight for the older style folded steel spring. The new rear sight is just unable to hold a consistent posture and makes the rifle inaccurate. I put a Williams peep on my Luxus and it is extremely consistent and accurate. The difference is the precision of the Williams vs. the poorly designed and made RWS rear sight. The rear sight issue is the reason I deducted a star from the rating.

I hear lots of complaints about the cocking effort that is just whining. A magnum springer is not a Red Ryder; if you want foot pounds of energy down range, you have to put even more in the rifle. The complaint about fasteners loosening is real, and Blue Loctite is a partial remedy. It is the nature of these beasts, in my experience, to shake stuff loose. Keep after the screws, Loctite them, and live with it. Otherwise, one can't get beter than a well maintained RWS Diana springer for accuracy, power and longevity.

Pretty accurate if you get to that stage by adjusting it. Trigger is exceptional!!!

A lot!!! Factory uses 0,4 gram light pellets to advertise velocity of 400 m/s (1320fps). Not a thing a would expect from such a brand like Diana. Quality is not at optimum for that kind of money and final finish of the riffle straight out of the box is awful.Screws will undone in 10-20 pellets. And not just stock screws, but barrel break screw also! Rear sight cheap plastic and loose.

ZR mount makes a lot of problems. Poor quality. Try to avoid it with better scopes.

Nice German build and quality. It's powerful and accurate. The finish was excellent. Good bluing and no nicks on the stock. Definitely a man's gun.

For what I paid i felt like it deserved a better rear sight system instead of plastic adjustment knobs that could also be prone to loosening up from the vibration. For being a scope eater better rear sights would be a good thing on this rifle.

I tightened up my screws but every then shots the stock would loosen from the action and I had to retighten. I finally used blue locktite and that seemed to work. Cocking is hard but that strong N-Tec system is the only way you'll get magnum power. It's a nice gun and will make anyone happy.

This is the 4th rifle 1st 3 didnt hold up or was defective on delivery. This rifle is nice to look at seems to be more accurate than most of the others.It seemed that the craftmanship on this one was better than the rest.

Fun to shoot.As far as the break barrels go this one seems to be a good one.

Nice looking, nice to hold and accurate.

Cant think of anything I would change except the Q.C. from Diana, I got my 1st 350 N-TEC .22 straight out of the box and the barrel was scratched and the stock was marked with something that looked to be oil. Also the was a glue like substance between the area were the scope goes and the stock. So took it back and got a replacement.....this one pretty much split in half, I got it home and checked her over, looked great then check the screws etc. Then took her for a shoot, after 15 shots went to cock it and the stock split and the whole Gas Ram pretty nearly took out my teeth. I took it back an the Gun Smith inspected it an told me that both screws that attached the stock and Gas Ram pretty much were stripped. I wrote an email to Diana and they apologised and told me that I was right about Diana making quality Rifles.......hahahaha. Oh well, 3rd times a charm....3months and no problems with the N-TEC 350.

Its powerful and nice to shoot but my Hatsan 125 .22cal shoots a whole lot harder. In New Zealand the Diana's cost $950.00. Dont think its worth it to be honest. I was told by the guy I brought it off that its the best Gas Ram Rifle on the market(he has over 30yrs experience with Air Rifles) But after the problems I had with Diana and their couldn't care less attitude its the 1st and last Air Rifle I will ever buy from them.

I have the .22 caliber 350 N-TEC. I like the power of this rifle, the good craftsmanship, the sights, the trigger, the safety, the accuracy, and especially the wood stock.

Somehow or another make it easier to cock, this thing is a monster to cock. My Hatsan 125 Vortex is much easier to cock and shoots a little harder. Bring it into the 21st century and make it a multi-shot rifle. Also offer it in a .25 caliber.

Mine shoots Crosman Premiers (14.3 gr.) at an average of 895 fps, and shoots them very straight. It also likes JSB 18.13s really well (775 fps average). All in all, this is a gun to shoot all of your life then hand it down to your kids to shoot. It is definitely one of the finest break rifles made.
My favorite break rifle though is the Hatsan 125 Camo Vortex in a .25 cal. It shoots harder, just as straight, is much easier to cock and cost more than $200 less. The .25 cal pellets are just so much more devastating to the target.

All the way around, it's a quality gun. A little on the heavy side, but not too bad. Yes, it takes 55 pounds to cock it. However, it also has that much more punch. Shooting the new Gamo Swarm today (a fun gun to shoot). Shooting 30 yards at a sheet of .032 aluminum. Most pellets bounced off. A few went through. Shooting the same with the N-TEC 350 magnum premium, EVERY pellet blew through with ease. We used 6 different pellets.

Probably nothing.

NICE GUN! I can see why they keep selling out.

This is the first Diana I've owned. Although I'd read some disappointing reports about declining QC at Diana, I was anxious to compare their product to other .22 pellet rifles I won. I'd been waiting for Diana to offer a gas-piston, as I do not like springers. The N-TEC arrived days ahead of schedule. Its *hair* trigger is insanely light right out of the box. This takes some getting used to but I like it! I can almost fire the N-TEC telepathically. ;-) The checkered Beech ambi stock is quite nice (albeit a minimal expectation of mine at this price point) but mine was quite a bit darker than I anticipated. The screws were tight (except for rear sights) right out of the box.

The gun is a bit HEAVY and longish, which makes it a bit awkward to heft. Provisions for a sling would have been appreciated. The rear, push/pull safety is a bit funky. I not a big fan of these fixed sights...fiber optic would have been nicer (and these are available). Also the rear sights were loose out of the box; I'd recommend a drop or two of blue thread lock. The "owner's manual" is marginal at best, and strangely advises not to leave the gun cocked for more than a few minutes. (I suspect this pamphlet is also intended to be sent out with some Diana Springers.) Maybe it was just my bad luck or someone at Pyramyd was rushed that day, but my N-TEC was packed VERY POORLY, in a shipping container 5-inches too short to enclose the factory box, and without adequate padding. The (muzzle) end of the factory box, protruding from the shipping container had taken quite a beating, however, the front sight did not seem damaged or bent. More diligence would be appreciated at this price point!

I'm comparing this new N-TEC 350 to my Ruger Yukon & Hatsan 95 Vortex...each less than HALF the price of the N-TEC 350. First, when they say cocking the N-TEC requires 55lbs, THEY MEAN EVERY BLOODY OUNCE! Second, I expect velocity discrepancies in airgun specs (N-TEC = 910fps/.22), but on a more fundamental level, the N-TEC DOES NOT WEIGHT 6.7lbs as stated in the specs here. That is sheer, wishful fantasy. I asked Diana directly and they replied: "the actual weight (without scope) is about 3,8 KG (8,4 lbs)." The Yukon WITH SCOPE weighs less (and cocks VERY easily & ships with an optics rail). The N-TEC is very accurate, even with fixed sights alone...but the barrel comes stuffed with cosmoline you'll need to clear out first. Third, the N-TEC seems as loud as a .22 rimfire to me (my Hatsan 95 Vortex is a tad quieter); the Yukon is the quietest for backyard plinking. I like the N-TEC, but the Yukon is comparable & a better (excellent!) budget alternative than the Vortex, IMO.

Quality and machining is impeccable. Recoil is sharp but predictable with consistent hold, I achieve best results with a slightly nose heavy artillery hold. Incredible power and achieving quarter size grouping at 15 meters with open sites with only 150 rounds through it! Why so few rounds? See below. Joy to shoot

A rear site that can withstand it's unique recoil. Would easily rate it firewall 5's if the rear site would stay intact.

Eat your Wheaties if your want this rifle, cocking it takes real effort. The only reason I have less than 200 rounds through it is because it ate two rear sites already, snapped off right at the hinge in both instances. The promising part is the distributor doesn't hesitate to send a replacement and is working diligently to resolve this issue.

Awesome beautiful flat shooting accurate couldn't be happier I call it the beast trigger is wonderful

More inserts for the sites

If you want a powerful 22 That shoes flat out to about 50 yards no problem then this is the gun for you
