I initially wanted to get the Surefire can, however after waiting for over 3 months I decided to get the Thunder Beast Ultra instead. The Thunder Beast is over 5 oz lighter than the Surefire. I played with the Surefire at the Shotshow and it is a nice can. However with this Thunder Beast attached to my Barrett MRAD and my Blaser Tac2 was the best decision I made. The can is very quiet and really helps with the recoil. I have no issues with the POA and POI when switching between the two rifles.
I would highly recommend this suppressor for anyone looking for the 338 Lapua can. I would. definitely do it again. I actually went on SS and purchased a Thunder Beast for my 308.
