AR57 () Full Auto

This is a select fire AR57 that I built in . It fires the same round as the P90 SMG, but offers the ease of use and familiarity of an AR15/ M16 style platform. Rate of fire is about 750 rounds per minute and uses the standard P90 magazine. --------- Follow Legacy Arms on Instagram and Facebook for more gun history, rare finds & firing fun!
