Just finished a build, well, almost. I'm using a Wilson .223 barrel and it's got a 5/8-24 thread, commonly found on 7.62 guns, for some stupid reason. AAC doesn't seem to offer a .223 brake with a 5/8-24 thread. They offer a 7.62 brake with a 5/8-24 thread though. My question is will the 7.62 brake fit onto a M4-2000 can? I'm basically wondering if the over all dimensions of the muzzle brake stay the same and they just drill a bigger hole. If so, I'll throw a 7.62 x 5/8-24 brake on this thing and be done with it. Unfortunately, I seem to be the only one on the internet who's had this problem, according to Google.
