Can you put a adjustable stock on a Rock River LAR-15 .223 cal Pistol or does it have to stay with the buffer tube only? do i have to change from a pistol registraion to a AR-15 registraion and do i have to give up my 10 round mag or do i just have to pin it and notify canada firearms? the lower is marked pistol only,now does that apply to canada or USA for the pistol only? advice please from everyone,thank you
