This 5.56 NATO AR-15 Full Auto Bolt Carrier Group is another precision quality part from Wilson Combat. The bolt is machined Carpenter 158 hardened steel to prevent wear and tear while still remaining flexible enough to prevent cracking. Featuring a parkerized finish on the outside and chrome lined gas key inside, this bolt carrier group will work in any 5.56 rifle, but it’s designed for full-auto, suppressed, or short barrel rifles.

Wilson Combat BCG’s

by -

Fast shipping from Primary Arms. Purchased two BCG’s at the same time. Made by two different suppliers for Wilson Combat. One of them came with a one piece gas ring and the other with the traditional three separate gas rings. BCGs used different gas key screws. The BCG with the one piece gas ring on the bolt was extremely difficult to actuate and after about 500 manual cycles by hand was still extremely stiff to operate. Replaced the one piece gas ring with the traditional three rings and things were good. BCG’s from Primary did not come with the WC logos as a third Wilson Combat BCG that I had purchased directly from WC did. After test fitting and head space checks on three different AR’s there were no issues and although not test fired yet I expect them to perform well.
