HK MR762 A4 7.62x51mm Semi-Auto Rifle 16.5" Threaded Barrel 20rd

The HK MR762 A4 delivers military-grade precision in a civilian-legal platform, combining HK's legendary HK417 technology with enhanced ergonomics. This 7.62x51mm NATO rifle features a cold hammer-forged barrel and ambidextrous controls for maximum versatility.

What Makes This Different

Built on HK's proven HK417 system, the MR762 A4 incorporates a short-stroke gas piston system that runs cleaner and cooler than direct impingement designs. The cold hammer-forged barrel delivers sub-MOA accuracy while maintaining durability through thousands of rounds. Unlike standard AR-10 platforms, this rifle features fully ambidextrous controls and HK's proprietary bolt extension system for enhanced reliability.

Key Features

• Cold hammer-forged 16.5" barrel with 5/8x24 threading for suppressors
• Short-stroke gas piston system with adjustable gas regulator
• M-LOK compatible handguard with integrated Picatinny rail sections
• Nine-position collapsible stock with adjustable length of pull
• Fully ambidextrous safety selector and magazine release
• 20-round steel magazine with anti-tilt follower
• Finger-grooved pistol grip for enhanced control

Field testing demonstrates consistent 1-1.5 MOA accuracy with match ammunition, while the gas piston system maintains function in adverse conditions where direct impingement rifles fail. The threaded barrel accepts standard 5/8x24 muzzle devices, making it suitable for precision shooting, hunting applications, and tactical use. Corrosion-resistant coating and stainless steel components ensure reliable operation in marine environments and extreme weather conditions.
