    Rotating breach airsporter information?

    Hi Chaps,
    its been a while since I have been able to devote any time to airguns but last night I began looking through my comics because I had a desire to read about the rotating breach airsporter....obviously I could not find the right magazine!
    Does anyone know of an online review for this rifle or have any basic information? Ive never seen one and my curiosity is killing me now that I have a few hours spare to read....
    Thanks in advance....is it different from the other BSA underlever with a rotating breach?

    The Airsporter is called an RB2. I have an immaculate, boxed one which is a joy to shoot.
    There is also one version of the Stutzen which has a rotating breech, I believe.

    In my opinion it is an excellent solution to the challenge of getting a pellet into an underlever; it is completely safe - unlike the AATX/Weihrauch 77/97 sliding guillotine arrangement, but it does not suffer from potential alignment/sealing issues as can the old tap arrangements.

    I'm not sure if I have any further info but if I find any, I'll post it on here.
    Happy Shooting!! Paul.

    Rb2

    Hi
    As Paul says they are a joy to shoot and the breech design which is shared with the SuperStar is very clever and well engineered

    This clever breech also doubles as a safety device as in previous Airsporters (ie. the rifle is safe until such time as the breech is rotated back into the closed position)
    The rifle has perhaps 1 flaw in that it does not have an anti-bear trap, and as the trigger is not a true 2 stage one, then setting it to achieve a very light pull weight (without a safe and sufficient sear engagement) can lead to a rap on the knuckles on loading if the sear slips. However I have not experienced this on my RB2
    Despite this, the trigger has a nice feel to it and my .22 RB2 is a very accurate rifle at long range
    My RB 2 is up there with my Mk1 Airsporter as a favourite rifle
    I spotted an article on the RB2 last night when browsing the web
    If I can find the link I will post it

    Hi, I'm about to refurbish my old and neglected mk1 Airsporter. It's interesting to note that the rotating breach is one part that needs no work, despite being a 1948 air rifle, that part of the mechanism is working fine and well sealed when closed. It's the trigger mechanism that needs work alonmg with a dodgy cocking action.

    A question from me here (if I can hijack the thread for a moment ) - What sort of muzzle energy are you guys with airsporters getting?

    Thanks

    Nigel

    The rotating breech that you have is tnot the rotating breech referred to in this thread. Yours rotates about an axis perpendicular to the barrel, whereas the RB2 breech rotates about the barrel axis.

    I have just bought a Mk1 and found that the trigger is loose on its pin to a degree that the gun would not cock reliably. I have fixed it by incorporating a further spring between the front of the sear and the trigger block. This causes the sear to move under the catch much more positively. The real cure would be to restore the fit of the components, but I am convinced that even with an 'as new' trigger, this mod would give a more positive action.

    A mk1 in good nick is likely to put out around 9.5 to 10.5 ft/lb. From what I have read and understand there is not much point in trying for more.
    Happy Shooting!! Paul.
