ok, I knew what you meant about conforming to czech military spec's, but wouldn't this barrel not be considered milspec because of its length? I was under the impression that in order to conform to milspec, all the criteria have ot be met don't they?
Like my AR has a 16" heavy barrel. It is 5.56 nato, but since it doesn't have that machined section on the barrel for the grenade launcher, doesn't it mean my barrel is not milspec?
I have always been confused with "milspec" guns or parts, especially on ARs
