Product description
AT3 Tactical is bringing you the best with this Top-Tier Black Nitride Bolt Carrier Group
Getting a high quality bolt carrier group (BCG) that runs well in your rifle is absolutely critical. AT3 offers this BCG with a black nitride finish, which reduces friction and increases surface hardness for a lifetime of use. The carrier itself features a full mass M16 cut for the best possible reliability in your AR-15 build.
BCG Made in the USA
The bolt itself features shot-peened 9310 steel construction, which is Magnetic Particle Inspected (MPI) to ensure there are no hidden cracks or stress points. The bolt also has a chrome-plated firing pin, and a mil-spec o-ring extractor already installed to ensure reliable extraction of spent brass.
AT3 sources these nitride BCGs from one of the largest suppliers of bolts and carriers in the firearms industry. When you buy a BCG from us, you’re getting a high-quality product that’s made in the USA, that’s trusted by dozens of brands and manufacturers, and we back every one with our AT3 lifetime warranty.
