5.7x28mm has quickly become the personal defense weapon caliber of choice for many. Offering near .22 LR levels of recoil and performance that rivals 5.56mm at close range it's no surprise why. Even with a 5" barrel this BANSHEE sacrifices nothing when it comes to features. The Mk57 platform is designed to use FN®* Five-seveN®* pattern magazines and still offers the full range of AR15 operational features like last round bolt hold open, and can utilize standard AR15 triggers.
