I am wanting to put an ak 74 muzzle break on my 7.62 ak. I found a Tapco one and it says it is for 14x1 LH which is what my threads are. It doesn't say if it will fit. It says it is for ak 74 and ak 47. I just don't wan to buy it and put it on my rifle and shoot it and get hurt. Any ideas? Kvar has one but I ain't paying $60 for one. Thanks
