Things I liked: 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).

Things I would have changed: 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.

What others should know: 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.

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

Things I would have changed: 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.

What others should know: ZR mount makes a lot of problems. Poor quality. Try to avoid it with better scopes.

Things I liked: 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.

Things I would have changed: 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.

What others should know: 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.

    What is the best mount and rings for this set-up... Hawke Sport Optics Airmax 30 SF 4-16x50 Rifle Scope, Ill. AMX Mil-Dot Reticle, 1/4 MOA, 30mm Tube on a Diana 350 N-TEC Magnum Premium Air Rifle Gas piston, 2-stage trigger, Beech stock, caliber - 0.22" ? I thought about the Leapers Accushot 1-Pc Mount w/30mm Rings, High, 11mm Dovetail, but not sure if I should use UTG Drooper Scope Rail, 11mm-to-Weaver Adapter, Compensates for Droop & Stops Scope Shift with weaver rings instead.

    • Mark from USA:

      Use the droop compensating mount w/weaver rings.

  • Francesco from USA asked:

    Can the UTG 3-9X40 1" Hunter Scope be mounted on this rifle?

    • Jordan from USA:

      Why not? just make sure you have dovetail rings.
