I have been thinking about replacesing the bircage compensator on my MP15 and there are so many out there, the best performing one that I have try'd has been the AK74 style comp. but I think it's quite gowdy looking. What's people opinion of the different ones like the "Y" comp, "shark" and such and others? I'm mostly looking for which one works the best hence I plan on using the gun for three gun competitions. Thanks for any help.
