Straight-pull speed with AR familiarity
The UTAS 516 brings straight-pull bolt speed to the AR-15 platform. With a 16″ barrel and AR ergonomics, the UTAS 516 offers faster cycling for skilled shooters while keeping the familiar ergonomics, controls, and modularity that make the AR family so adaptable. It’s an excellent choice for shooters who want a unique action in a recognizable, serviceable package.
Purpose-built performance — light, fast, repeatable
Engineered for repeatability and quick follow-ups, the straight-pull mechanism reduces the time required to cycle the action compared to traditional reciprocating charging operations. The UTAS 516’s barrel profile and gas system are tuned to deliver consistent .223 Rem / 5.56 NATO performance across common factory loads, giving practical accuracy and reliable function for range, training, or duty use.
Modern ergonomics and modular accessory fit
The rifle features a free-float M-LOK handguard, full-length top rail for optics, and an AR-style lower for immediate compatibility with standard grips, stocks, triggers, and magazines. Ambidextrous safety and magazine release controls increase usability for left- or right-handed shooters. The 16″ barrel length balances maneuverability and ballistic efficiency for general-purpose use.
Built for reliability and user serviceability
UTAS designed the 516 to be straightforward to maintain with common AR tools and parts. The upper/lower interface, pinned/loctited components, and proven barrel extension geometry make routine maintenance and parts replacement simple for armorers and home users alike. Confirm exact SKU details (barrel contour, muzzle device, included accessories) before listing or shipping.
