Few carbines make an impact like the XO 16-inch has. The XO 16-inch is compact and extremely maneuverable. Its gorgeously designed aesthetics are functional as well, significantly cutting weight. The 16” Bartlein-blank barrel is like a scalpel, producing groups well into the sub-moa range with quality optics and ammunition. Superior accuracy is further enhanced with the addition of a Geissle Super Dynamic Enhanced (SD-E) two stage trigger and NEMO’s recoil reducing bolt carrier—an industry first. This carbine is ideal for CQB, Hunting, and long range precision alike. The XO will take your shooting to exceptional levels.
