The Geissele Automatics Reliability Enhanced Bolt Carrier Group is a full mass M16 profile full auto rated BCG built out of premium materials and coatings for long term durability and reliability. The carrier is machined from 8620 steel and the cam pin is machined from H13 steel. The entire AR-15 Bolt Carrier Group is coated in Nanoweapon which is a Chrome-Nitride finish that increases smoothness and surface hardness for corrosion resistance and cleaning. The carrier also features longer upper rails to prevent carrier tilt and increase feeding reliability. The bolt is forged from Carpenter 158 steel and undergoes a proprietary heat-treating process that reduces impurities and makes it stronger and more consistent than other C158 bolts. Additionally, each bolt undergoes high pressure testing, magnetic particle inspection, and a rigorous inspection process. If you are looking for an AR-15 5.56 Bolt Carrier Group that will last a lifetime, you can’t go wrong with the Geissele Automatics Enhanced BCG.

  • M16 Profile

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.

A really nice BCG

by

This Geissele BCG is really nice. The finish and machining are perfect, I'm impressed.

Incredible

by

I purchased this BCG only because it was on sale. Although I have more than a few Geissele parts on this particular rifle, I already had a Lantac NiB enhanced BCG, so I didn’t really need this one; but I was wrong.
My first outing with this BGC, I saw a huge difference. My groupings at 100 yards (16” barrel, 3X optic, 55gr LC ammo) went from 2” to 1/2” instantly. After 300 rounds, it looked like it was still freshly lubed, where my Colt or Lantac NiB BCG’s look pretty nasty after the same round count. Cleaning it was was a breeze. I had chunks of carbon just falling off. Not even my NiB BCG’s were that easy.
All in, this Geissele BCG is the best I’ve ever seen. Hopefully, someday, they will make this in .308.
