A lot of guys don't like a brake that is nosiey, and this one is, but it works great. It depends if you want a reduction in barrel rise and recoil. I have one of their A2 AK-Shorty's that I have shot in IPSC for some time now. I think everyone's view of "proper" is very subjective. I like it a lot, I think it looks fine, but to me looks are second fiddle to effectiveness and I find the AK brake to work very well. Go to the Bushy web site and look at one, or email me and I'll send you a jpg of mine with an Aimpoint. The baynot will slip over the AK brake, I tried it, and it will line up with the 14.5" barrel. For a while I had a Bushy V-Match 16" Fluted with the AK Brake. That was a nifty set up. BTW, I don't think the bayonet will work at all with 16" barrels but like I said the 14.5" is fine.
