Agree with above. Surefire RC2. There are some that are quieter. Others with a better mount. Some with less backpressure. And yet others that are more durable. But the Surefire is the best combination of the above.
Can’t really give a review because my can is still in jail, but I just bought a Dead Air Sandman S. I like the design of the quick detach muzzle device. Some look like shit without the can. Plan on running it on my 556 AR15, my 308 AR10, and a 6.5 PRC bolt action. Should be able to quickly switch back and forth. And it was in stock.
A lot of options I was considering, like the Omega, were not. The clock doesn’t start until the cans at your FFL, so a six month wait on a B/O + the 8-10 month wait on the feds would suck pretty hard.
