10.5 Inch 5.56 NATO Barrel by AT3 Tactical

This 10.5 inch long 5.56 NATO barrel is a perfect match for a shorty AR-15 build that won’t break the bank. This barrel has a corrosion-resistant black nitride finish, with 4150 CMV steel construction for a long service life. The proven Government profile provides plenty of support for suppressors, which are a natural fit for an SBR in this caliber.

This barrel uses a .750″ diameter gas block, plus a Carbine length gas tube, both of which you can snag here at a lower, bundled cost. If you’re looking to start fresh with a complete upper assembly, check out our selection of upper and handguard combos! For this barrel, we’d recommend a handguard around 9 inches long to ensure you can access the muzzle threads. Which is ideal if you plan to suppress it!

All NFA/ATF Rules Apply
You may use this barrel with a lower receiver that is a Registered SBR, Machine Gun, or Pistol. Possession of this barrel along with a Non-NFA lower receiver is Prohibited, except when installed on a Pistol configuration firearm.
