Lmt Defense
The LMT Defense AR-15 5.56mm full auto bolt carrier group is a mil-spec BCG built to the standard that has equipped U.S. military and professional shooters for years. This is the real deal—a full-auto rated carrier and bolt assembly designed for durability and reliability in both suppressed and unsuppressed AR platforms. Whether you're building a rifle from the ground up or upgrading from budget-bin parts, this BCG delivers the kind of performance you expect from a manufacturer with a proven track record supplying complete weapons systems to those who depend on their gear.
LMT Defense has manufactured AR-15 full-auto BCGs and replacement components for military and professional use, and this group reflects that heritage. It's the same basic design found in standard M16/M4 platforms, meaning parts commonality and support are straightforward. If your build calls for mil-spec reliability without compromise, this carrier group is a solid foundation.
The full-auto rating means this BCG handles the demands of selective-fire operation, but it works equally well in semi-auto rifles. Suppressors, standard barrels, various gas systems—this group cycles reliably across the spectrum. Black finish completes the package with a professional look and corrosion resistance.
