AR Upper Parts
AR upper parts are where a build either comes together or falls apart. The handguard, bolt carrier group, gas system, charging handle, muzzle device — every one of those components affects how your rifle runs, how it feels, and how long it stays reliable. Whether you’re doing a fresh build, replacing a worn part, or upgrading what came stock on your rifle, getting quality components from names you trust matters more than most shooters realize until something goes wrong.
You’ll find upper parts here from Aero Precision, BCM, Faxon, Midwest Industries, Lantac, and more — manufacturers that AR builders actually reach for, not whatever happened to be on clearance somewhere. Bolt carrier groups, gas blocks, gas tubes, handguards, barrel nuts, charging handles, muzzle devices — the parts that matter. Inventory is tracked in real time, so what you see listed is genuinely available, not a backorder situation waiting to surprise you after checkout.
Find the parts your build needs and order today — we’ll have them on the way fast.
