UTAS 516 Straight Pull 12.5″ W/BCM QRF-12 – 223Rem/5.56 NATO

Compact speed — straight-pull action in a short package

The UTAS 516 (12.5″) with BCM QRF-12 brings straight-pull bolt speed to a compact AR-15 chassis. This build pairs the rapid cycling advantages of a straight-pull mechanism with the maneuverability of a 12.5″ barrel and the rugged BCM QRF-12 free-float handguard — ideal for users who want a fast-handling, accessory-ready carbine for CQB, patrol, or range work.

Designed for low-profile agility and high control

A 12.5″ barrel keeps overall length tight for close-quarters maneuvering while preserving the ballistics expected from .223 Rem / 5.56 NATO at typical engagement ranges. The straight-pull action reduces the time and movement required to cycle the rifle, helping experienced shooters speed up follow-ups without departing from standard AR ergonomics.

BCM QRF-12 handguard — rugged modularity

The BCM QRF-12 style free-float handguard gives a slim, sturdy mounting surface with M-LOK slots for accessories and a continuous top rail for optics and backup sights. Solid construction and proven mounting geometry make it easy to add lights, grips, and lasers while maintaining a clean, professional look.

Familiar controls, modern capability

The UTAS 516 keeps standard AR controls and magazine compatibility so users benefit from the broad aftermarket and user familiarity of the AR-15 family. Ambidextrous controls, comfortable pistol grip, and an adjustable stock let shooters configure the rifle quickly for individual preferences and mission needs.
