If you�re considering a .308 patterned AR platform in calibers other than the tried and true .308 then look no further. The Executive Order (XO) in 20-inch trim is a lightweight accurate hard hitting carbine. Available only with a 20-inch Proof Research barrel you can choose between .308 .260 Remington and 6.5 Creedmoor chambering to fit your shooting needs. The longer barrel ensures that you can extract maximum velocity from your projectiles. Ambidextrous controls make operating the XO a cinch for any shooter. - 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 - PROOF RESEARCH 20� 1:10 twist carbon fiber wrapped barrel - NEMO dual chamber compact muzzle brake 6AL-4V Titanium - Quick switch .875 journal gas block Suppressed Unsuppressed settings 4140 IONBOND coating - Severe duty threaded stainless gas tube with +2-inch extended 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 (38.5 inches) Weight unloaded (8.2 pounds)
