I'm putting together a 5.45x39 featureless as and the last piece needed will be the muzzle brake. I'm assuming I could use a 5.56 muzzle brake without any problems. I know the brake will lose some effectiveness with the slightly smaller 5.45 bullet, but the real reason for the brake will be to stay featureless.

Anyone have any different opinions? Maybe there are 5.45 specific brakes and my google skills are weak. Thanks.

Featureless AR type?
556 brake will work just fine. Or no brake at all. Or thread protector.

I went with the Cavalry Arms .223 muzzle brake. It fits, works fairly well on my .223s, and I had an extra laying around when I started the build. Pretty much any .223 brake will work. I think Brownell's has the Cav Arms ones in the $20-25 range.

I take it you are doing an AR? Otherwise if its an AK why not use a AK74 sight base and use the actuall ak74 brake?

i ran a troy MB(5.56) on my 5.45 AR worked fine no issues at all and cool fireballs when it gets darker out :)
