Re: muzzle brake port angles
there is the vias type which ar the ones with holes all the way around. Then you have the Holland type with the fish gills. nice thing about these kinds is that they dont kick up as much dust as the vias type. then you got the clam type such as the jp. Very effective brake but they look dorky to some people. as for hole angle on the vias type I dont know which angle is best.
I dont know who ever came up with the imaganary word of "Over Gunned"
