sailskidrive said:I would go with one of the DPMS/SR25 patterned guns instead of the Armalite as there are a ton of manufacturers supporting that design package. While the Armalites are nice why limit yourself to their proprietary design? Also, beware of CMMGs offering as they have a lot of dimensional fit issues that arent in spec with the standard pattern. There are several reviews on You Tube that detail the problems.

I have to disagree, the DPMS pattern is by far the most widely accepted and used by DPMS, Bushmaster, LMT, MEGA, Knights, Fulton Armory, POF, CMMG, etc. Armalite is really the only odd man out.
