Barrett Firearms 17123 REC7 DI 5.56 NATO 16" 31-Round FDE Carbine

The Barrett 17123 REC7 DI Carbine in 5.56x45mm NATO represents a purpose-built platform for operators who demand reliability across variable suppressed and unsuppressed duty cycles. Chambered in 5.56 NATO with a 16-inch barrel, this direct impingement carbine delivers consistent performance in patrol, training, and precision-focused applications where modularity and minimal maintenance are non-negotiable.

The REC7 DI features a lengthened gas system engineered to cycle reliably whether running suppressed or unsuppressed—a critical design choice that eliminates the carrier tilt and bolt bounce common to standard systems under suppressor backpressure. Upper and lower receivers are machined from 7075-T6 aluminum, then hardcoat anodized and Cerakote-finished for corrosion resistance and precise color matching across all components. The 30+1 capacity feeds standard AR platform magazines. Included flip-up iron sights provide immediate backup aiming capability. The Flat Dark Earth receiver pairs with black Magpul furniture and a 6-position adjustable stock, enabling users to optimize length of pull for body armor, plate carriers, or bare kit. Total weight runs 13 pounds, keeping the platform light enough for sustained training operations.

This carbine is purpose-designed for law enforcement patrol, military training environments, and serious civilian marksmen who require a suppressor-capable 5.56 platform without sacrificing reliability or requiring constant tuning. The integrated design and premium materials justify the investment for operators running this rifle in suppressed configurations or high-round-count environments where duty-cycle consistency matters.

The REC7 DI occupies the premium direct-impingement segment, differentiated from piston-driven alternatives by lower reciprocating mass, easier maintenance, and proven accuracy—particularly relevant for carbines where precision support tasks are secondary but essential. The lengthened gas tube and 16-inch barrel optimize velocity for target-distance engagements while maintaining the handling characteristics operators expect from a short-stroke platform.
