AR15 9mm Barrels

Rhineland Arms 9mm barrels for AR15s. These are made of 4140 steel and have the QPQ coating on them. The ramp to the chamber is beveled smooth for reliable feeding. These work great in the New Frontier C5 receivers. We left the alignment pin out as it is not needed for these types of barrels, however the hole is drilled and we include the pin if you want to use them.

Barrel threads are 5/8-24

Barrel lengths are 6.5″ and 16.5″

Chamber is 9mm

Blowback operation only
