UTAS 516 MK18 MOD 1 STRAIGHT PULL 10.5″ – 223 REM/5.56 NATO

Compact Power. Built for Control. Ready for Action.

The UTAS 516 MK18 MOD 1 Straight Pull Rifle redefines compact precision in the modern tactical rifle market. Chambered in .223 Remington / 5.56 NATO, this 10.5″ straight-pull platform delivers exceptional control, accuracy, and compliance — ideal for shooters who demand high performance in restricted jurisdictions.

Designed after the proven AR platform but adapted for manual operation, the MK18 MOD 1 brings a new level of reliability and compliance-ready versatility to the UTAS 516 series.

Tactical Design Meets Practical Engineering

The MK18 MOD 1 features a short 10.5-inch free-float barrel, precision-machined receiver, and a rugged straight-pull bolt system for rapid, intuitive operation. Built for precision in close to mid-range engagements, its compact design makes it ideal for tactical training, range work, or confined field scenarios.

Key engineering highlights include a cold-hammer-forged barrel, M-LOK compatible handguard, and an enhanced trigger assembly for a clean, predictable break. The shortened system retains balance and controllability without sacrificing reliability or consistency.

MOD 1 Enhancements & Performance Upgrades

The MOD 1 configuration takes the UTAS 516 straight-pull rifle to a higher standard of functionality:

• Enhanced straight-pull bolt system for smoother cycling and fast manual follow-up shots.

• 10.5″ cold-hammer-forged barrel optimized for .223/5.56 performance in short-barrel setups.

• M-LOK handguard for modular accessory mounting and heat dispersion.

• Adjustable stock for customizable length of pull and improved handling.

• Compact receiver and rail system compatible with optics and accessories.

• Lightweight construction for improved maneuverability and reduced fatigue.

Every detail is designed for shooters who want AR-style ergonomics and combat-level dependability in a compliant, straight-pull format.

Compliance Without Compromise

The UTAS 516 MK18 MOD 1 is designed for regions where semi-automatic rifles face restrictions — offering the same build quality, feel, and performance advantages of a modern tactical rifle, while remaining fully compliant.

With its manual straight-pull action, it’s perfect for competitive precision shooting, dynamic range work, and professional training where control and legality matter equally.
