Love it

by trey dudley

Bolt carrier group is nice and tight, functions flawlessly and I will be getting another soon for my s&w ar15. Primary arms was a measure to deal with, and teleported to my door in just 3 days halfway across the country

Building my current project I have searched for quality and best deal combined for many of the parts. In doing this primary arms has now become my "go to" site as they offer such a wide variety and have great turn around.

Fail Zero Review

by Travis Eller

Excellent BCG, finish is amazing. Very slick very consistant. Feels great with very minimal lubrication. Smooth and all great internal parts and proper staking. This is one of only 2 BCG I recommend.
