MK111 Compound Pistol .223 Wylde: Redefining AR-15 Performance
Engineered for shooters who demand the highest level of control and accuracy, the MK111 Compound Pistol in .223 Wylde represents a breakthrough in firearm technology. This isn’t just another AR-15 pistol—it’s a purpose-built platform that addresses the fundamental challenges of pistol-caliber shooting with an innovative recoil mitigation system that dramatically improves shooter performance.
Advanced Recoil Mitigation Technology
At the heart of the MK111 Compound Pistol lies a proprietary recoil system that redirects gas energy to counteract muzzle rise. Unlike traditional buffer systems that simply absorb recoil, this compound mechanism actively works to keep your sights on target. The result? Faster follow-up shots, improved accuracy during rapid fire, and reduced shooter fatigue—whether you’re on the range or in a tactical scenario.
Superior .223 Wylde Chambering
The .223 Wylde chamber provides the perfect balance between .223 Remington and 5.56 NATO compatibility. This hybrid chamber design allows for safe firing of both cartridges while delivering exceptional accuracy with match-grade ammunition. You get the versatility to use readily available military-spec ammo alongside precision handloads, all from a single platform.
