Hey y'all. I have been reading for the last couple of years about the relative merits of AKs, ARs, and other rifles. Each has it's advantages and it's disadvantages, that's part of the fun! One thing I have not seen discussed is linearity. The AR (to the best of my knowledge, which could be wrong) is the first shoulder fired weapon to have a completely linear discharge from the end of the barrel (or muzzle break as the case may be) all the way through to the shoulder. Until Stoner's design, all the shouldering was below the firing line of the rifle. Having the shoulder below the firing line ought to cause or at least facilitate muzzle rise. I'm a neophyte here, but I do understand a bit about physics. Am I making too much of this, or is that small physical advancement somewhat over looked? I'll hang up and take your replies!
