PWS MK114 MOD 2-M 6mm ARC 14.5" P&W - AR-15 Rifle

Built for precision shooters who refuse to compromise on reliability, the PWS MK114 MOD 2-M delivers a duty-ready 6mm ARC platform in a pinned 14.5" configuration — combining the proven long-stroke piston system with ambidextrous controls and premium ergonomics straight from the factory.

The PWS MK114 MOD 2-M is a semi-automatic AR-15 rifle chambered in 6mm ARC, featuring a pinned 14.5" barrel for a compliant 16" overall length, built around PWS's long-stroke piston system for reduced fouling and enhanced reliability across high-volume and suppressed applications.

PWS long-stroke piston system for reliable operation: Unlike direct impingement designs, the long-stroke piston system cycles the action with significantly less carbon fouling in the upper receiver — delivering a cleaner, smoother shooting experience over extended strings of fire and in suppressed configurations.

Pinned 14.5" barrel for SBR-free compliance: The 14.5" barrel is permanently pinned with the PWS FRC 3-port compensator to achieve a compliant 16" overall length — giving you the handling advantages of a shorter barrel without the NFA paperwork of an SBR.

PWS PicLok handguard — Picatinny and M-LOK combined: The innovative PicLok handguard integrates both Picatinny rail sections and M-LOK attachment slots into a single handguard, giving you the direct-mount rigidity of Picatinny where you need it and the slim M-LOK profile everywhere else — without sacrificing ergonomics or accessory compatibility.

Ambidextrous controls throughout: The precision-machined ambidextrous receiver pairs with a Radian Raptor ambidextrous charging handle for full left- and right-hand compatibility — no aftermarket modifications required for left-handed shooters or support-side manipulations.

Premium furniture and trigger from the factory: Magpul MOE SL stock and MOE K2 grip deliver proven ergonomics and control, while the Mil-Spec enhanced trigger provides a consistent pull for improved shot-to-shot accuracy right out of the box.

Chambered in 6mm ARC and built on a standard AR-15 platform, the MK114 MOD 2-M accepts AR-15 compatible magazines and accessories. The pinned 14.5" barrel with PWS FRC compensator meets federal OAL compliance requirements for non-NFA configuration. Compatible with standard AR-15 optics mounts and accessories.

The precision-machined ambidextrous receiver is finished in black anodize for corrosion resistance and long-term durability. The enhanced buffer system works in conjunction with the long-stroke piston to manage recoil and extend component service life across high-volume shooting.

An ideal platform for precision rifle competition, hunting applications requiring flat trajectory and reduced recoil at distance, and duty or patrol configurations where a compliant barrel length and suppressor-ready operation are both priorities.

Primary Weapons Systems is a U.S.-based manufacturer known for their long-stroke piston AR-15 and AR-10 platforms, trusted by military, law enforcement, and precision shooters demanding enhanced reliability over direct impingement alternatives. The MK114 MOD 2-M is backed by PWS's limited lifetime warranty.
