  1. Are AR-15 Accessories universal?

  3. Which AR-15 accessories can improve accuracy and reduce recoil?
    Upgraded triggers, muzzle brakes, and free-float handguards are all AR-15 accessories for enhancing precision. A muzzle brake controls recoil, while a free-float handguard minimizes barrel pressure, allowing more consistent shots.
  4. How do I choose the best AR-15 accessories for home defense?
