The Primary Weapons Systems PWS MK111 Compound SBR 223 Wylde 11.85 FRC Comp blends a proven long-stroke piston system with a modern AR-style layout for a smooth, reliable shooting experience. Its Mod 1 proprietary piston upper is paired with a MK1 Mod 2 ambidextrous lower, delivering excellent ergonomics, reduced gas blowback, and dependable performance when used with or without a suppressor. The 11.85 inch barrel is capped with the PWS FRC compensator to help control muzzle rise and maintain fast follow-up shots.

This short-barreled rifle is chambered in .223 Wylde to safely and accurately run both .223 Remington and 5.56 NATO ammunition, making it a versatile choice for range use, training, and practical shooting. The included Radian Raptor ambidextrous charging handle, M-LOK handguard, and enhanced buffer system round out a feature-rich platform that favors control and comfort over harsh recoil. Shooters looking for a refined, soft-shooting AR will appreciate the thoughtful engineering and attention to detail that Primary Weapons Systems brings to the MK111 Compound SBR.
