Pardon my ignorance on this... My experience has solely been with carbine setups.

I grabbed a blemished lower off Aero’s site for the heck of it. It has a rifle tube and buffer installed, which I will remove to build that lower as a pistol, for unrelated reasons. However, I’m thinking about uses for the rifle tube.

Will this run on effectively with a 12.5” SBR? (I’m not particularly interested in purchasing A5 buffers, though.)

Can I pick up an A1 stock and just slide it on?

Thank you
