BRT OPTIMUM Barrels

[Clint]

We have high expectations for velocity.

These haven't been chrono'ed yet, but the 11.5" should be similar to a normal 12.5".


Larger 5/8-24 threads are stronger and better, especially when suppressors are involved.

Any 30 cal suppressor will work and quite a few 5.56 QD suppressors have 5/8-24 mounts available for them.

The 5/8-24 SilencerCo ASR Mount works with the Specwar 556, Specwar 556K, Saker 556, Saker 556K.

The 5/8-24 AAC 51T mount works with the M4-2000, 556-SD and Mini-4.

The 5/8-24 Griffin Taper mount works with the Reece 5 and Optimus Micro w/ optional taper mount interface.

What is the Velocity with M193 and M855 in the 6P? I was Looking at getting a 12.5 barrel because I have 3 10.5 SBRs, and kind of want the extra inch. Also why 5/8x24 threads?
