PWS MK114 MOD 2 Upper Receiver in 6MM ARC: Precision and Reliability Redefined

Elevate your AR-15 platform with the Primary Weapons Systems MK114 MOD 2 Upper Receiver Assembly chambered in 6MM ARC. Designed for shooters who demand exceptional accuracy, reduced recoil, and unmatched durability, this upper combines advanced engineering with practical performance enhancements. Whether you're engaging targets at extended ranges or pursuing game in challenging environments, the MK114 MOD 2 delivers consistent results you can trust.

Why Choose the PWS MK114 MOD 2 Upper?

• Long-Stroke Piston System: Unlike direct impingement systems, the PWS piston design reduces fouling, runs cleaner, and enhances reliability in adverse conditions. This means less maintenance and more time shooting.
• 6MM ARC Caliber: The 6MM ARC offers a flat trajectory, excellent ballistic coefficient, and effective terminal performance, making it ideal for precision shooting and medium-game hunting out to 1,000 yards.
• MOD 2 Enhancements: This version features an improved handguard with enhanced ergonomics, a more robust barrel profile, and optimized gas system tuning for smoother operation and better accuracy.
• Built to Last: Constructed from high-quality materials including 4150 chrome-moly steel barrel and 7075-T6 aluminum receiver, ensuring longevity and resistance to wear.

Key Features and Benefits

The MK114 MOD 2 is engineered for shooters who value performance and reliability. Its 14.7-inch barrel with a pinned and welded muzzle device ensures compliance with legal requirements while maximizing velocity and accuracy. The adjustable gas block allows for fine-tuning to match your ammunition and shooting conditions, reducing recoil and improving follow-up shot speed. The free-float handguard provides ample space for accessories like optics, lights, and bipods, without affecting barrel harmonics.

This upper is compatible with standard AR-15 lower receivers, making it an easy upgrade for existing rifles. It comes complete with a bolt carrier group and charging handle, so you can install it and start shooting immediately. Whether you're building a new rifle or upgrading an old one, the MK114 MOD 2 offers a significant improvement in performance.

Ideal Applications

• Long-Range Shooting: With its 6MM ARC chambering, this upper excels in precision competitions and target shooting at extended distances.
• Hunting: Effective for medium-sized game like deer and hogs, thanks to the 6MM ARC's energy retention and ethical knockdown power.
• Tactical and Defense: The reliable piston system and durable construction make it suitable for law enforcement, military, and home defense scenarios.
