Gun Parts
Upgrade, repair or build with barrels, triggers, stocks, grips, handguards, muzzle devices and replacement parts. We list over 14,800 gun parts from Magpul, Hogue and Strike.
Getting the right fit
Fit is everything with gun parts. Match the exact make, model and generation of your firearm, since a Glock 19 Gen 3 and Gen 5 do not share every part, and AR-15 parts can differ between mil-spec and commercial dimensions.
Barrels and muzzle devices also need the right thread pitch. For triggers and internal parts, a qualified gunsmith install is the safest route if you are not comfortable doing it yourself.
Gun Parts FAQ
How do I know a part fits my gun?
Check the product title and specifications for your exact model and generation. If a listing covers a range of models, confirm yours is on the list before ordering.
What thread pitch do I need for a muzzle device?
Check your barrel. Most 5.56 and 9mm barrels use 1/2x28 and most .30 caliber barrels use 5/8x24, but confirm the thread on your barrel or in your owner's manual before you order.
