Primary Weapons Systems MK116 .223 Wylde AR-15 Rifle - 16" - 1x 30rd Mag

The Primary Weapons Systems MK116 MOD 2-M brings a long-stroke piston system to a versatile .223 Wylde AR-15, giving shooters cleaner-running operation than a traditional direct-impingement rifle. Built for range sessions, home defense, or competitive shooting, this AR-15 rifle delivers reduced recoil and reliable cycling across a wide range of ammunition.

Features:

• 16.1" barrel, 1:8 twist, chambered in .223 Wylde
• Long-stroke piston operating system
• 3-setting adjustable gas block
• FRC compensator
• Free-float aluminum M-LOK handguard
• Fully ambidextrous safety selector, bolt catch, and charging handle
• Adjustable synthetic stock
• Black anodized finish
• 6.8 lb weight, 35" collapsed overall length
• Includes one 30-round magazine

The long-stroke piston system keeps combustion gas out of the receiver, reducing fouling and cutting felt recoil for faster follow-up shots compared to a direct-impingement AR-15. The 3-setting adjustable gas block lets shooters fine-tune gas flow for suppressed or unsuppressed use, optimizing reliability across different ammunition types and conditions, and the FRC compensator redirects muzzle flash and reduces rise for better visibility in low-light scenarios. The .223 Wylde chamber lets the rifle run both .223 Remington and 5.56 NATO ammunition while holding tighter tolerances than a standard 5.56 chamber.

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 MK116 MOD 2-M's versatile .223 Wylde chambering.
