Restrictions

Top takeaways

  1. The 9mm AR-15 Modern Series 5.5" barrel is made from 4150 Chrome Moly Vanadium steel with a QPQ corrosion-resistant finish and is designed for both Colt/RR and Glock style AR builds.
  2. It operates on a blowback system without the need for a gas block or tube and has a 1:10 twist rate with 1/2-28 threaded muzzle for suppressor compatibility.
  3. Installation requires a specific magwell conversion for UZI mags or a dedicated 9mm lower for Glock mags, and it's crucial to ensure muzzle devices have a bore that allows a 9mm round to pass freely.
