READY GUNNER PURCHASE GUIDE
The Daniel Defense MK18 RIII pairs the legendary 10.3-inch MK18 barrel with the lighter RIS III Rail Interface System in flat dark earth. The free-float M-LOK handguard keeps the continuous Mil-Spec 1913 top rail while cutting weight, and the fully ambidextrous lower receiver, GRIP-N-RIP charging handle, Daniel Defense buttstock and pistol grip make it fast-handling for left- or right-handed shooters. The 10.3-inch cold hammer forged, chrome-lined barrel with 1:7 twist is the same length trusted for CQB operations. Ships with one 32-round Daniel Defense magazine.
NFA NOTICE: This is a short-barreled rifle regulated under the National Firearms Act. All NFA rules apply — transfer must go through a Class 3 dealer.
