Caliber: .308 Winchester - Barrel Length: 16 inches - Full Length: 34.25 inches - Weight: 8.2 lb - 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. - NEMO full ambi-control upper and lower receiver set billet 7076-T6 Cerakote tungsten grey - 15” 6061 M-LOK modular rail 1.83” internal diameter steel QD mounts rotation limited - Lightweight heat dissipating barrel nut 7075-T6 - 7075-T6 7 position “Carrier Cradle” anti-tilt receiver extension - Tuned steel faced buffer system - Chrome silicon recoil spring - Bartlein blank in house machined barrel 1:8 twist 416 stainless - NEMO dual chamber compact muzzle brake Heat treated 4140 IONBOND coating - Quick switch .750 journal gas block Suppressed Unsuppressed settings 4140 IONBOND coating - Severe duty threaded stainless gas tube mid-length gas system - PATENTED recoil reduction carrier 8620 heat treated Nickel Boron coated - High Pressure bolt 9310 heat treated Cryo’d shot peened MPI Nickel Boron coated - Tool steel extractor heat treated IONBOND coated - Titanium through drilled takedown and pivot pins - Ambidextrous safety selector - Ambidextrous charging handle 7075-T6 - Mil-Spec forward assist - Sling compatible latch plate and properly staked castle nut - Geissele Super Dynamic Enhanced (SD-E) two stage trigger First stage 2.3lbs Second 1.2lbs - MAGPUL MIAD grip - MAGPUL CTR Mil-Spec diameter carbine stock - MAGPUL 20 round Gen3 P-MAG - Overall length collapsed (34.25 inches) Weight unloaded (8.2 pounds)
