Whether for home defense, range days or as a trusted truck gun, the BANSHEE in .45 ACP is the compact powerhouse ready for anything. The MkG Radial Delayed Blowback operating system is a proprietary innovation from CMMG, blending advanced engineering with practical enhancements to deliver superior performance in pistol caliber AR platforms First introduced in 2017 with the original .45 ACP MkG platform, Radial Delayed Blowback has since revolutionized pistol caliber AR designs across the entire CMMG lineup Through precise engineering, Radial Delayed Blowback not only addressed key operational challenges found in traditional straight blowback systems but also introduced benefits in weight reduction and softer recoil By minimizing felt recoil and reducing the mass of the bolt carrier group and buffer system, Radial Delayed Blowback delivers a smoother shooting experience than conventional straight blowback systems can achieve Originally developed as a leap forward from traditional straight blowback designs, the Radial Delayed Blowback system offers improved performance and reduced felt recoil The compact action version of Radial Delayed Blowback builds on the success of the original design, further reducing system size while maintaining the hallmark reliability and soft recoil The addition of a fixed ejector in the RDB system represents another step forward, showcasing CMMG's ongoing commitment to integrating new technologies into the Radial Delayed Blowback platform Every CMMG product is covered by our lifetime quality huarantee, a testament to our unwavering commitment to quality and craftsmanship We stand behind our work, every CMMG product is backed by our lifetime quality huarantee, protecting against defects in materials and workmanship
