  • Jake from USA asked:

    Would a moderate strength fifteen year old be able to cock this?

    • Tyler from USA:

      I would think so

  • Jon from USA asked:

    is the 48 and 52 the same rifle

    • Tyler from USA:

      Same action, different stocks

  • John from USA asked:

    What scope mount should I purchase with this gun? Thanks

    • Matthew from USA asked:

      What type of rifling is done on diana barrels?

      • Maurice from USA asked:

        On the Diana model 48, can the whole front sight assembly be removed and a sound suppressor be installed?

        • Lajos from USA asked:

          What is the LOP of this rifle?

          • Harry from USA asked:

            Most parts for this 'Air Arms" are not identifyable from available schematics nor available for purchase from any "Googled" search. I have a RWS/Diana 48/52, purchased from "Pyramid Air" about 1993?, It has about 2000+- rounds thru it when spring broke and discovered rear end of plastic spring guide had also broken into pieces upon disassembly. Only replacement parts for repair are from alternate source after much research. Suggest purchasing a much cheaper air gun, and avoid RWS/Diana.

            • Harry from USA:

              Just got the RWS/Diana 48/52, .177, back together this afternoon with the Vortek spring assembly installed. I used a liberal amount of their lube on the spring but not as much as they suggested. Very light lube to the Piston seal (original) which appears to be in excellent condition. Cleaned everything with degreaser and alcohol. The new guide doesn't allow the piston to travel as far back as the old which results in the cocking action to need an extra effort to engage the locking mechanism, and the auto safety does not fully activate. I'll need to investigate further to find what is causing this issue. The gun is quieter and initial results indicate a more consistant grouping of rounds fired, although it was only at 10 yards. Will play with it some more later and mount a drop compensator rail and a Leapers for a longer range evaluation.

          • Randall from USA asked:

            Is there a difference between an umerex Rws and a Diana Rws?

            • Paul from USA:

              This rifle is made by Diana of Germany RWS was a distributor, now Umerex is the distributor for Diana.

          • Rudedawg from USA asked:

            Will a 48 in .22 kill a raccoon and if so at distances of 30 yrds or less?

            • Harry from USA:

              Yes it will dispatch most game with proper round placement, which is difficult at distance with this airgun. The round nose ammo are not as effective as hollow point as the latter have more expansion and internal damage than the round point.

            • Grayland from USA:

              Yes head shot eye or just below the ear. Heavy pellet 21 grain.

          • James from USA asked:

            will the Leapers UTG 30mm SWAT 3-12x44 AO Rifle Scope work on an RWS model 48 / 52? If so what mounting hardware would you recommend?

            • paul from USA:

              Yes. I have that scope on mine. Also used the UTG droop compensating mount with the supplied rings.

            • Grayland from USA:

              Try the new rws bullseye mounts or rws lock down mount.

          • Ernest from USA asked:

            anyone have a noisy firing cycle? My .177 48 has a sound kind of like a honk when firing, not when cocking. How noisy is your 48 when firing?

            • Ernest from USA:

              three distributors (including Umarex) never heard of such a condition. I was advised to lube the chamber. I put in two drops of RWS chamber oil and let it sit overnight. Sounds like the piston was dry, doesn't it.Well, my two month old .177 self destructed and is now being re-built by Umarex who needed to be convinced that I should not be charged for the job. Beware if you have an RWS that is noisey.

          • DON from USA asked:


            • Paul from USA:

              Ashley is correct you need to know the scope objective lens plus the scope tube size in order to recommend the ring size.

            • Ernest from USA:


            • Ashley from USA:

              Thats going to depend on what scope you get because it depends on rather it has a 1" or 30mm tube as well as selecting the right hight for the objective.

          • Brad from USA asked:

            Since this rifle has a fixed barrel, do you feel that using a droop compensating scope mount is necessary? Ideally, I'd like to use a set of scope rings that clamp directly to the receiver dovetails.

            • RALPH from USA:

              I have to argue with you on this one. My Diana 48 will not zero without one. I suppose that's why it came with one installed on it.

            • Paul from USA:

              It all depends my RWS52 which is a fixed barrel needed a droop compensater.

            • Jerry from USA:

              Droop rail is not necessary for the fixed barrel

          • Marty from USA asked:

            Is there a video showing how to lube a RWS 48

            • Stephen from USA:

              As far as I can tell no. But Figure 10b was rather confusing. You have to remove the trigger guard and stock. On the bottom side you will see a hole with the spring in it. As far as the barrel, your guess is as good as mine.

          • david from USA asked:

            Is the BSA scope compatible with rws 48 side cocker. Scope says will not handle magnum spring

            • Billy from USA:

              I agree... I put a brand new "magnum rated" BSA 6-24x on a RWS 350 in .177 and it tore it apart in less than 50 rounds. I then put a Leapers 6-24x on it and have not had any problems with it since. I repaired the BSA and put it on a RWS 34P in .177 and it works fine on it (less recoil). The leapers scope is heavier, perhaps therefore, higher quality.

            • Neal from USA:

              Paul is right, my 48 destroyed a BSA scope inside of 100 rounds. I am using a Leapers now that still shoots great after several hundred rounds.

            • Paul from USA:

              I would definitely look into getting a leaper scope.
