AR-15 Barrels & BCGs

AR-15 Barrels, Bolt Carrier Groups & Charging Handles

Shop AR-15 barrels, BCGs, and charging handles in multiple lengths and profiles to suit precision builds or compact platforms. We list gas system types, twist rates, and threading for each barrel and provide high-resolution photos plus torque/suggested specs. Bolt carrier groups are grouped by material and finishing (nitride, chrome-lined) so you can match durability needs. Use quick filters for barrel length (10.5″, 16″, 20″), gas type, and thread pitch. All listings include compliance flags for restricted shipping areas and serialized alternatives when applicable.
