Details
The MK18 RIII takes our MK18—unmatched in size, weight, and performance—and adds a fully ambidextrous lower receiver that allows both left- and right-handed shooters to operate the bolt catch, safety selector, and magazine release without having to move or remove their dominant hand from the rifle’s grip. An ambidextrous GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters as well. This remarkably maneuverable rifle also features a 9.5 inch RIS III rail—modeled after the revolutionary RIS II two-piece handguard developed for SOCOM—that features M-LOK attachment for lighter weight. It surrounds a free-floating, Cold Hammer Forged 10.3 inch Government Profile barrel, which is the same length in use for the MK18 upper most commonly used for CQB operations. This rifle also comes with the ergonomic Daniel Defense Buttstock and Pistol Grip.

- Mark18Man, I gotta see it craftsmanship means a lot for this company, I purchased my Mark 18 last year only to shoot it around January. It feels very smooth, and it feels definitely like quality however I must say it is very gassy like a pigs fart. The blowback is very intense in the rear nothing comes out the charging handle but when it’s cycles, get ready for that cloud of smoke lol.
