DPMS DR-15 RIA | 5.56 NATO | 16in | DP51655111871

The DPMS DR-15 RIA is a 5.56 NATO-pattern semi-automatic rifle built with a 16-inch A2-profile, chrome moly vanadium barrel finished in 4150V nitride and a 1/7 rifling twist. It pairs a 13.5-inch M-LOK handguard with a fixed DPMS A2 stock and is configured in a California-compliant feature set with a non-threaded muzzle. For an optic that complements this platform without exceeding $1,000, consider a Vortex Strike Eagle 1-6×24 for versatile close-to-mid-range sighting.

Use cases for this rifle include recreational target shooting and competitive utility/limited-course events where a reliable, AR-style platform with a standard 16-inch barrel is appropriate.
