    Do you know if he was using Marauder mags for this? They look strangely familiar...

    They are Marauder magazines- they were/are the easiest for people in the US to get ahold of generally (sell for about $16.00 CAD each- but not common in Canada as Crosman is reluctant to send them as the Marauder is not shipped to Canada at all so far). The problem is, in my opinion, the Marauder magazines are a pain-in-the-a$$ to load, a more "open" magazine like that used in the Umarex products would have been more productive, but that would, I assume, make the rotating mechanics a bit tougher as the teeth are on the rear of the magazines.

    Maybe I can acquire one of the JRA units for "experimentation".
    I'd say I care- but I'd probably be lying...

    The problem with the JRA breech is that the barrel had to be machined as well.... The Cobra breech solved that but it again has disappeared.... I think the design of that has been "borrowed" by another company and is back in production for the 22XXs (bhm?).... I designed one as well, couldn't get a reliable CNC shop to fly with it....
