You may want to check out the B&T SRBS762 or 556. I've run the SRBS762 Ti on 7.75-16" 5.56 barrels. My only nit is the sparkle show. Definitely lower backpressure than the SiCo 36M.

My Maternal Grandmother, RIP, would've handled that with one hand, then dressed it out. I don't understand these people getting punked by waterfowl.

A few years back, a former, now current, convict was caught with a 4" K-frame in his prison purse after a traffic stop around Elizabeth City, NC.
