This is a minty Daniel Defense MK18 that qualifies as a short-barreled rifle due to its 10in barrel. From their site, “The MK18 AR15 style firearm is unmatched in size, weight, and performance, and features the picatinny quad rail Daniel Defense provides to USSOCOM. The RIS II picatinny quad rail features a Bolt-Up System that has been rigorously tested prior to fielding by USSOCOM. The 10.3 inch Cold Hammer Forged barrel is the same length in use for the MK18 upper most commonly used for CQB operations. The independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters. This rifle also comes with the ergonomic Daniel Defense Buttstock and Pistol Grip.” It’s hardly been used, has a mint bore and virtually no handling wear. Fully transferable on a form 4. Magpul MOE rail vertical grip installed. Six-position adjustable stock. Comes with Magpul 30rd magazine.
