AWCYs Scarpion with AR Internals Chambered in 22LR

AR FGC All The Things

Thank goodness it’s only insanity if you expect a different result, because AR fire control groups work no matter what you put them in. If you looked at an Evo 3 recently and said, “Man, I really wish this was an AR,” you’ve come to the right place. The ScARpion 22 is a melding of AWCY?’s legendary Scz0rpion release with AR internals, creating a .22LR platform that’s the best of both worlds.

Released by cursd, with assistance from some of the biggest names in GunCAD, this wonderful love-child has plenty to offer builders who enjoy their guns with a side of interoperability.
