Could someone advise me a fixed mag lower pistol build? I have been researching info all day on the regulations and requirements in Mass, and just wanted some clarifications of the do's and don'ts of building one. I I just picked up a JC Arms fixed mag lower, I know I will have to use a pistol brace and pistol buffer-tube, but what else am I restricted by in terms of weight and barrel lengths, attachments , ect? Any advice would be greatly appreciated!
