is the barrel contour/thickness the same from end to end on the A4 Carbine? i've seen pics of ARs where some barrels are thinner beneath the hand guards. i was told this is called a government profile. the reason why i ask is i've located an A4 Carbine and a similar model with the HBAR barrel. i do plan on hunting coyotes with my AR and wondered about accuracy between the two. thanks.
Our standard barrel weight is an HBAR. We do have lighter-weight offerings in some styles. We can't guarenty accuracy from a government profile, so we don't offer one.
