Curious if anyone has experience or run this? I quite like the Gamma design, but am on a kick to both reduce blast and weight with breaks.  Curious if anyone has reports on switching from the long 3-chamber 6.5 Gamma break, to the shorter (A2 FH sized) .300 BO version.  And if doing so reduced relative blast any, or had a notable difference in compensation performance?  

Here is the 6.5 Gamma brake

Here is the lighter, smaller, (and less blasty?)) .300 BO version.



My biggest worry is the vent holes for .300 BO version are going to be designed for that low-P low gas round.  And so aren't necessarily tuned for gassy high pressure 6.5 CM, and the thing might be over-agressive at thrusting the barrel downward?

Just curious if anyone has tried it.  My 6.5 Gamma works quite well, I do know that.
