Douglas Barrels has been cutting precision rifle barrels since 1948, and they are the OEM supplier behind some of the most accurate Mk12 builds in the community. This 16" stainless steel blank has been contoured to the correct Mk12 Mod H profile — the same heavy-under-rail taper used on the Crane-built Mk12 Mod 0 and Mod 1 Special Purpose Rifles — and chambered in .223 Wylde / 5.56 NATO for maximum ammunition flexibility and accuracy.
Cut-rifled 1:7 twist stabilizes everything from 55gr ball to 77gr OTM Mk262 Mod 1, making it equally at home on the DMR range or running service ammo on a clone build. 16" length means no NFA paperwork, no pin-and-weld, and no compromise on the Mk12 profile for shooters who want the look and ballistics of a SPR without the tax stamp. Threaded 1/2"-28 muzzle, stainless bead-blasted finish, with a mid-length gas port already drilled to correct Mk12 dwell-time spec. Order yours today and build the Mk12 you actually want to shoot.
