Daniel Defense DD4 SPRIII | 5.56 NATO | 18 in | MFG# 02-191-16291-047

The Daniel Defense DD4 SPRIII is a semi-automatic AR-style rifle built around an 18 in MK12-profile cold hammer-forged barrel chambered for .223 Rem/5.56 NATO. It uses a 15 in RIS III handguard with a full-length ARCALOCK bottom panel and features fully ambidextrous controls and a Magpul PRS Lite stock for an adjustable, stable shooting platform. For an optic that pairs well with this configuration at a street-friendly price point, consider a Vortex Strike Eagle 1-6×24, which supports both close work and precision at extended ranges. Typical applications include precision target shooting and designated marksman roles where a robust, accurate semi-automatic platform is required.
