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.)
AndyLate, that was my error. I ‘assumed’ that the enhanced receiver extensions used for A5 systems were simply rifle-length buffer tubes designed for adjustable stocks. Thank you for clarifying.
