PISTOL, BANSHEE, MkGs, 40 S&W, 8"
Although there may not be as much love for .40 S&W as there was a few years ago from some shooters, it still stands as a favorite of many shooters and law enforcement agencies alike. With an 8” barrel, there’s not an ounce of power this MkGs BANSHEE™ in .40 S&W leaves behind. The MkGs platform lower receivers are designed to accept small frame 9mm/.40 S&W Glock-pattern magazines. Magazines for either caliber must match the caliber the upper group being used is chambered in.
Available in a variety of cerakote finish options, the BANSHEE series represents the most innovative AR pistols and SBRs available today. From the quick deploying RIPBRACE®, to the stylized receivers and EML™ handguards, every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. With full length M-LOK® slots on both sides and the bottom of the handguard as well as M-LOK between the top picatinny rail sections, you’ll always have enough space for those must have accessories. With the wide range in ammunition available, and the option for suppressed operation, the available Action Tuning Kit will allow you to tune your system even more for added flexibility and smoother operation.
