The Brownells BRN-10 is a faithful recreation of the original ArmaLite AR-10 as delivered to Portugal and Sudan in the late 1950s and early 1960s — before the design was simplified into the M16/AR-15 family. The BRN-10 uses the original AR-10's aluminum/steel barrel, triangular handguard, and period-correct furniture. Brownells commissioned the replica specifically for the retro AR collector market.
