XTS AR-15 Bolt Carrier Group Features The XTS Bolt Carrier Group is precision machined to meet military specifications ensuring consistent fit and function inside an AR-15 upper receiver. Heat treating the carrier and bolt improves resistance to the wear and stress generated by repeated cycling which helps the components hold tolerances over a long service life. The black nitride finish reduces friction between the bolt carrier and receiver walls promoting smoother cycling and easier cleaning after range sessions. Precision manufacturing and uncompromising quality control together give shooters a dependable core component for their rifle build. Finished entirely in black the XTS Bolt Carrier Group fits cleanly into a standard 5.56 NATO chambered AR-15 upper without the need for modification. Nitride coatings are prized for their corrosion resistance meaning the BCG withstands moisture and powder residue better than uncoated steel parts over time. This durability makes it a solid choice for shooters replacing a worn factory carrier or building a new upper from the ground up. Backed by careful machining and heat treatment the XTS Bolt Carrier Group is available at GrabAGun for builders seeking dependable function at an accessible price.
