BRT OPTIMUM Barrels

[MistWolf]

It's cool to have lower cost hand guard options.

Torquing the muzzle device directly against the hand guard cap causes it to spin and is a bit of a pain to line up.

Dealing with a spinning cap won't be be much of a thing. Installing the handguards to hold the cap from spinning while applying the final torque to the muzzle device should do it.

We like using an extra gas block...

I prefer to eliminate unnecessary weight. That's why I usually thread the suppressor directly to the barrel

How important is subsonic operation?

For the present, not at all.

There may be a use case for supersonic only, suppressed or unsuppressed.

I haven't had a chance to shoot the 300 much. I chose it be cause it should perform better from barrels shorter 10 inches than the 5.56. For the moment, I can't envision a practical use for the subsonic 300 and with the differences in POA/POI and gas drive, setting up an AR to shoot both seems more complicated than its worth. The Wilson HAMR or the 7.62x39 are likely more practical choices for my purposes, but the entrance fee for the 300 BLK was cheaper.
