Purpose: The barrel is one of the most critical components of a rifle. Its primary purpose is to contain the high-pressure gases produced when the cartridge is fired and direct that energy to propel the bullet forward at high velocity. Inside the barrel, the rifling (spiral grooves) spins the bullet, stabilizing it in flight for improved accuracy and range. The barrel’s length, material, twist rate, and profile also significantly influence the rifle’s overall performance, recoil, maneuverability, and effective velocity.

Features: The 7.5" Parkerized Heavy Barrel is a 9mm AR-9 barrel designed for pistol-length blowback builds. It features a heavy profile made from 4150 steel with a parkerized finish for durability and corrosion resistance. It has a 1:10 twist rate optimized for stabilizing common 9mm ammunition and uses a standard blowback gas system. This compact, robust barrel is a budget-friendly option for building short, maneuverable 9mm AR pistols or PDWs for home defense, range, or competition use.
