Details:

The bolt carrier group (BCG) is the driving force behind the performance of your AR-15 / M16 rifle. If you are looking for the best performing BCG, you'll find that the American Build Arms (AB Arms) version fits the bill.

The AB Arms bolt carrier is machined from 8620 steel and coated with black phosphate for corrosion resistance. Chrome-coated AISI 8740 steel is used for the firing pin to ensure resilience even under the hardest use.

This AB Arms AR-15 Bolt is milled out of Carpenter 158 steel to very tight tolerances, resulting in a perfect fit in the bolt carrier. It is then heat treated and shot peened to further improve the durability. The nickel boron coating on this bolt gives it a layer of natural lubrication, which repels fouling and improves reliability. AB Arms has once again set a new standard for BCG quality with this product!

A Perfect Fit for Your AR-15

When selecting a BCG for your AR-15, two elements are crucial in making the right choice: fit and durability. Beginners and seasoned shooters alike understand that precision-made parts are critical to accurate and consistent AR-15 performance. That’s why the AB Arms BCG is an excellent choice for AR builds and performance upgrades.

In our experience as well as that of our customers, this AB Arms BCG is one of the smoothest operating bolt carrier groups on the market, and after putting it through a strenuous test at the range we were astonished at the minimal wear on the part.

Many shooters overlook the BCG as a crucial element to AR-15 performance, instead opting for upgrades like muzzle devices or custom AR-15 stocks. When we start custom builds here at Wing Tactical HQ, we definitely consider those types of upgrades, but we also put extensive amount of time and effort into choosing high-performance core components that give our setup an edge in even its barest form. In many cases, this BCG by AB Arms is part of that build.
