Thread: WTB AR15 Barrel 16"

If it's for service class shoots NZSRA has stipulated mid length gas system for LMT clones-I got caught out by this
Off course this may not matter to you.



"Barrel: The Barrel must be no longer than 16 inches and will use a mid length gas system. The barrel will have a diameter under the hand guards of no more than .730 inch and the gas block diameter must be .75 of an inch. The barrel forward of the gas block area may be no larger than .740 inch. The barrel must be made from Chrome-Moly steel and may be chrome lined. It may have a Parkerised, black oxide or QPQ (Salt Bath Nitro carburised, Melonite, Tenifer etc) finish. The barrel must safely chamber 5.56 NATO ammunition. The gas block may be attached with a single pin, clamped on or held on with set screws. The Muzzle may be fitted with a Surefire WAR Comp or an A2 flash hidder. "
