Primary Weapons Systems MK114 MOD 2M 6mm ARC AR-15 Rifle - 14.5" P/W - 1x 15rd Mag

The Primary Weapons Systems MK114 MOD 2-M brings long-stroke piston technology to the efficient 6mm ARC cartridge, giving long-range shooters flat trajectories and minimal recoil with reduced fouling compared to a direct-impingement AR-15. Built for suppressed shooting without the reliability headaches of gas blowback, this AR-15 rifle delivers sub-MOA accuracy potential out to extended distances.

Features:

• 14.5" barrel, 6mm ARC, 1:7.5 twist (P/W)
• Long-stroke piston operating system
• Three-position adjustable gas block
• FRC 3-port compensator, pinned and welded for 16.1" overall length
• PicLok hybrid Picatinny/M-LOK handguard
• Radian Raptor ambidextrous charging handle
• Mil-spec enhanced trigger, 5.5-6.5 lb pull
• Magpul MOE SL stock
• Anodized black finish
• 6.9 lb weight
• Includes one 15-round magazine

The long-stroke piston system keeps combustion gas out of the receiver, reducing fouling and carbon buildup for consistent performance even after thousands of rounds, particularly useful for suppressed shooting where a direct-impingement AR-15 would otherwise blow gas back toward the shooter. The three-position adjustable gas block lets shooters tune the action for different ammunition types, suppressors, or environmental conditions, addressing the over-gassing issues common to fixed-gas systems. The 14.5-inch barrel's 1:7.5 twist rate stabilizes 6mm ARC bullets for long-range precision, and the FRC 3-port compensator is pinned and welded to bring overall length to a legal 16.1 inches without an SBR stamp.

Primary Weapons Systems builds long-stroke piston AR-platform rifles known for their reduced fouling and suppressor-friendly operation, applying that same engineering to the MK114 MOD 2-M's 6mm ARC chambering.
