AR Bolt Carrier Groups

The bolt carrier group is the heart of your AR — it’s what makes the rifle cycle. Every round fired, every case extracted, every fresh cartridge chambered runs through the BCG. Get a quality one and your build runs smooth. Cut corners here and you’ll be chasing malfunctions on the range wondering what went wrong.

AR bolt carrier groups are stocked here in mil-spec and enhanced configurations across a range of finishes — nitride, PVD, and chrome — compatible with common calibers including 5.56 NATO and 6mm ARC. Whether you’re doing a fresh build or replacing a worn or underperforming BCG, there are proven options from brands like Toolcraft, Cryptic Coatings, Aero Precision, and Fail Zero — names that serious builders and competition shooters actually trust and run.

This is a veteran-owned, licensed FFL dealership based in Bradenton, Florida, with live inventory that’s verified in real time. What’s listed as in stock is genuinely. With over 43,000 products across the catalog and most orders going out within one business day, you’re not going to be left waiting around wondering if your part is real. BCGs ship direct to your door — no FFL required — with flat-rate shipping and no surprise fees showing up at checkout.

Find the finish and spec you need, add it to cart, and it’ll be on its way fast.
