The NEMO XO Steel in 6.5 Creedmoor (brand part no. XO65CM-22B) is a semi-automatic AR-10-pattern rifle built around a 22-inch 416R stainless steel barrel with a 1-in-8-inch twist, giving long-range shooters the reach and consistency 6.5 Creedmoor is known for. NEMO machines the upper and lower from matched 7075-T6 billet aluminum with full ambidextrous controls, runs a 48-position adjustable gas system for suppressed or unsuppressed shooting, and fits a patented Nickel-Boron-coated Recoil Reduction Bolt Carrier to soften recoil impulse. Among AR-platform rifles in the AR rifles category, the XO Steel favors precision shooters who want a steel-barreled 6.5 Creedmoor build for medium-to-long-range work.
