The 5.7x28mm has cemented itself as a greatly effective round with less recoil than 5.56mm at closer ranges. With a 8" barrel this ultra-compact BANSHEE will fit almost anywhere. This BANSHEE is built on our Mk4 AR15 platform, which uses a standard AR15 lower receiver and our improved 5.7x28mm AR conversion mags. The EML7 handguards feature M-LOK slots at 3, 6 & 9 oclock positions and a full-length Picatinny top rail for accessories as well as an integrated handstop. Includes 32rd magazine.
