GrabAGun’s AR & AK Parts aisle is where builds get finished and battle-worn rifles come back better than new. Browse uppers, lowers, bolts, and springs built for the hard-running AR-15, beefy AR-10, or legendary AK-pattern rifles. Fine-tune recoil and reliability with precision Gas Tubes & Gas Blocks or drop-in trigger kits from respected makers like ALG Defense and Aero Precision. Stretch reach and hold zero with free-float Handguards that accept M-LOK or Picatinny accessories without adding weight. Whether you’re chasing a sub-MOA varmint rig or a bomb-proof truck gun, you’ll find stripped receivers, parts kits, buffer tubes, and everything in between at prices that respect your ammo budget.

Every part ships straight to your door—no FFL needed—so long as local rules allow. Need a fresh muzzle device?
