The DC SPEC 11.5" Barrel DT15 is designed to be in between the DUTY and COM SPEC giving you the best of both worlds. It will eat most all .223 and do well with NATO pressure ammo.

11.5" Government Carbine 1:7. Our barrels are produced in-house, from raw bar stock to finished product. We drill, ream, rifle, contour, and assemble with the help of our fully automated and robotic driven production line. All of our barrels are properly stress relieved after rifling, and extensions are torqued after nitride. Our quality control system ensures that all barrels are dimensionally correct and bores fall well within their individual tolerance.
