I am doing a 700-Tactical-AAC-SD Build and i am not sure which stock & magazine to get. The AICS stock comes with the detachable mag, and goes for about $860. The B&C Adjustable Medalist and the Surgeon Mag kit would cost about $800. The buget would be maxed-out with either one, but I could swing it. What are your thoughts on either of these set-ups? Any input would be greatly appreciated.
