You might also check out the Spike's Dynacomp or Spike's Dynacomp Shorty (We should have pics up soon).
Griffin Armament M4SD Comp is also a good choice. Lots of reviews state that the Griffin comp is very similar in performance to the BC, but a little cheaper. It also has much more suppressor compatibility than the Battle Comp.
If you're not looking to pin/weld on a 14.5" barrel, you might look at the Spike's Dynacomp Shorty and Griffin M4SD as well? They'll be substantially quieter than the PWS, and still perform well. My M4SD Comp on my PLR-16 223 AR pistol mitigates 110% of the muzzle rise. It actually pushes the muzzle down a bit. The PWS is probably a better flash hider than the Dynacomp/M4SD/BC
Damn you that dynacomp looks like a good use for my $30 coupon
