Parts & Upgrades

AR-15 parts and upgrades from the makers that serious builders trust: Aero Precision, Bravo Company, Ballistic Advantage, Faxon, Radian, Geissele, Timney and Magpul. This is where you find barrels, bolt carrier groups, triggers, handguards, muzzle devices, magazines, stocks and grips, and complete build kits, along with the Glock and CZ parts we carry for pistol owners.
Almost everything here is a non-serialized part and ships straight to your door. The one exception is a stripped receiver, which is a firearm under federal law and transfers through your local FFL like any other gun. If you are deciding what to upgrade first on a factory rifle, read AR-15 upgrades that actually matter before you spend the money. It ranks the parts by how much difference they make at the range rather than by how good they look in a photo.
