The SW 500 is chambered with the BigBurger Inc.-standard 8.9mm Fragmenting Flechette, the first weapon to use this unusual round. Control is excellent, and the high wound potential makes it a good weapon for close encounters. The Bernstock model is an uptuned version of the Chapman piece, made by Dozz Bernstock, co-founder of the Mosquito Forge.
