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 5in barrel this Mk57 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.
Available in a range of cerakote finishes, the Banshee series represents the most innovative AR pistols and SBRs available today. From the stylized receivers and EML handguards, every Banshee is tailor-made to be the personal defense weapon you can always depend on. The EML4 handguards feature M-LOK slots at 3, 6, and 9 o'clock positions and a full length picatinny top rail for accessories as well as an integrated handstop.
