For shooters looking to stretch the .223 Rem and 5.56 NATO cartridge to its limit, the Criterion Bull Contour AR-15 barrel is the answer. A favorite among long range and varmint hunter enthusiasts, this 416R stainless steel barrel features a beefy profile designed to accommodate .936 gas blocks. Each barrel is hand lapped and held to match grade tolerances. These barrels feature an 11 degree target crown and a .223 Wylde chamber.
Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith.
