Thread: Owing an A-cat AR-15 + a bolt action rifle with 'MSSA' features

Going back to the original questions re AR mags that fit into non-semi auto rifles and owning an A cat rifle that it will fit. There is a simple way to solve this if you want to own both. You simply alter the fit of the magazine like Izhmash did with the Saiga. You can do one of two things: Add a small lump / lug to the semi auto rifle that blocks the magazine from fitting then adjust you semi auto mags so that only they fit. This way you can use your 7 shot semi mags in you pump / bolt or waht ever action you have, but the Hi cap ones will only fit the non semi auto and will not engage the semi.

If you can show that in its current form the magazine will not function in the semi but will fit into the non-semi then you should have no problems. Thus if you have a Saiga then the AK Hi cap mags will not fit without it being altered to accommodate them.
