Standard 5.56 AR-15 Bolt Carrier Group

Standard 5.56 AR-15 Bolt Carrier Group Description

This Standard Bolt Carrier Group is compatible with AR-15 Upper Receivers. This Standard BCG line comes in TiN [Titanium Nitride (Gold)], NiB [Nickel Boron (Silver)], and Black Nitride. These BCG’s are drop-in ready, standard weight, and a high-quality component that is precision machined to perform for tens of thousands of rounds and provide reliable and consistent performance. The outside dimensions and ALL three interior dimensions of our carrier are grinded and smoothed, giving our BCGs a near friction-less surface finish. To ensure long-term reliability and corrosion resistance, coatings are done by industry-leading finishers H&M for their Blacknitride+™ and WMD for their NiB-X finish. These deliver the utmost durability and improved lubricity for our premium Standard M16 Cut BCG. These BCG’s are a high quality standard Mil-spec component for any AR-15.
