I’m here at the Blue Ridge 3-gun match, a fun, challenging match over natural terrain at the Rockcastle Shoot Center near Bowling Green, Kentucky.

A company called Rubber City Armory (whose Director of Operations is none other than Chris Cerino, of Top Shot fame) is prototyping a new concept muzzle brake here where you can control the gas exhaust directions by plugging certain holes with screws.

This seems to make a lot of sense to me. For many AR-15 shooters, right handers will experience muzzle rise up and to the right (left-sided ejection port ARs up and to the left) and so you can insert screws in the lower left ports so the gas pushes in that direction to somewhat neutralize the recoil. Or you can insert screws however you see fit for your load and preferences.

Here are some never seen pics. In order: Top View, Bottom View, close up of the Top View with a view of the threaded holes. There will be eight holes. What do you think?
