The ALL-NEW Tactical Edge Arms® (MPI) complete bolt carrier group is fully assembled and made in the U.S.A.. Bolt carrier group (auto version) for your AR15, M16, or M4.

The bolt assembly is machined to the correct 9310 steel, Nitride coated and shot peened for increased strength (Nitride coating is 15% stronger than Nickel Boron, run it dry and its scratch resistant), includes tool steel machined extractor and ejector, Mil-Spec Extractor Spring, and is HPT (High Pressure Tested) and MPI (Magnetic Particle Inspected). Prior to shipping, all T.E.A Bolt Carrier Groups are test fired for function. As such, the Bolt Carrier Group will show handling marks consistent with these quality control procedures.

Written by Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE), Chief of the Firearms Technology Branch ...M16 bolt carriers are not designed and intended solely and exclusively for use in converting a weapon into a machinegun and are not any combination of parts from which a machinegun can be assembled. Further, an M16 bolt carrier is not a firearm as defined in the GCA or a machinegun as defined in the NFA. An M16 bolt carrier is simply a machinegun part and as such its domestic sale and possession is unregulated under the Federal firearms laws. It is not unlawful to utilize a M16 machinegun bolt carrier in a semiautomatic AR15 type rifle.

    Best Nitride BCG on the Market

    Posted by Brian N on Dec 5th 2021

    Made the mistake of purchasing two of the many Black Friday deals on bolt carrier groups thinking a heavily discounted price off an expensive BCG meant quality...I was wrong. "Properly staked" must mean something different to every manufacturer looking for ways to speed up getting product out on the shelves. Not the case with TACTICAL EDGE!!! Where do I begin? TACTICAL EDGE Nitride coating is very even, clean and smooth with absolutely no burrs on the carrier rails (can't say that about one of the other brands I bought). The gas keys are 100% properly staked with metal being displaced to prevent them from ever coming loose! I love this BCG so much I ordered two. While I know everyone is waiting patiently for the DLC version to become available (and I'm sure they're awesome), you will not find a better Nktride BCG than this bad boy on the market! Consistent quality, properly made and just as smooth as butter!

    Passes all of the “function checks” Uncle Sam taught us. Clean lines. Smooth.
