In one of the best kept secrets of National Match history, the Army Marksmanship Unit has been shooting AMU-built National Match grade AR-10's for the past two years. Their work has culminated with the acceptance of the ArmaLite AR-10NM for use "across the board" in NRA Service Rifle competition. The result is the new ArmaLite AR-10NM rifle. Superbly accurate, this rifle is ready for long distance match domination. Equipped with ArmaLite's National Match Two Stage Trigger, matched receivers, extended elevation NM sights installed into ArmaLite detachable sight bases, and ArmaLite exclusive stainless steel match barrel matted to ArmaLite's MIL STD 1913 Free Float Rail Handguard.
