9MM AR 15 BARREL 5.5″ , MODERN SERIES 9mm barrel blanks
The 1/2-28 x.400 full profile threads on this 9mm barrel 5.5 inch Modern Series Barrel are crafted of 4150 Chrome Moly Vanadium steel. Also, the craft comes with a QPQ Corrosion Resistant Finish.
-Designed to work with both Colt/RR and Glock style AR builds.
-Compatible with standard mil-spec uppers. There are also numerous dedicated 9mm upper options that work.
-Requires the use of a unique magwell conversion (Colt/Rock River style) with UZI mags or a dedicated 9mm lower with Glock mags.
- 9mm on an AR15 platform operates by blowback and does not need a gas block or gas tube.
- Threaded 1/2×28 instead of 1/2×36 to give you greater versatility when choosing a suppressor.
- Integrated feed ramp and barrel extension.
- Since the “barrel extension” is an integral part of the barrel, the length stated is the true overall length. For example, an 11” 9mm barrel has the same outer dimensions/length as a 10.5” 5.56 9mm ar barrel.
- IMPORTANT: A standard 1/2×28 flash hider will not have enough clearance for a 9mm round to pass.
- Before installing a muzzle device, ensure a 9mm round will drop freely through the muzzle device bore.
