The Brownells BRN-180 Lower Receiver is a forged lower receiver that pays homage to Eugene Stoner and Arthur Miller's original AR-18 rifle designed in 1963 with all the right visual lines, yet brings in modern AR-15 lower receiver features for a product that gives you the best of both worlds. While the original AR-18/AR-180 receiver was constructed from stamped steel, the BRN-180 Lower Receiver is built from 7075 aluminum forgings and is up to the standards of modern AR-15 lower receiver construction. Don't worry though, we've made sure that these forged lower receivers have the cosmetic 'weld' marks of the stamped originals. Mfg: Brownells
