This video is the second part of a two-part series on a deeper dive into certain Surefire cans - as well as compatible cans, such as the B&T SRBS - focused on live fire videos.

All footage was recorded on the same day, low pressure, under cover, with concrete barriers and a retaining wall behind me. I was shooting M193 55gr ammo which is higher pressure and naturally louder than some other 556 offerings: but not appreciably so.

Hosts used were a FBI SWAT clone with a 11.5 inch Colt Commando HBAR, a near clone G$ URG-I with a 14.5 inch SOCOM profile barrel, and my Mk 12 Mod 3 project with a Centurion MK12 Mod 0/1 18 inch barrel. Cans used were a B&T SRBS-762, Surefire SOCOMs 556-RC2, 556-RC3, 556-SB2, 762-RC2, and 300-SPS.

My favorite can is still the RC3 for 556 guns, costs of it aside, the net health benefits at the sacrifice of some performance is fine by me. I do really like the SB2 though after shooting it more.
