Wise Arms started as a normal gun shop and did some custom AR builds. We slowly evolved into a manufacturer producing lower receivers. WIse Arms currently runs 10 CNC machines. We also have a cerakote robot that is 1 of 30 in the world. We at Wise Arms provide a quality product at a reasonable price and ensure excellent customer service. All of our firearms will come factory with a 3.5lb trigger, billet lower, canvas carry bag, cerakoted finish, and a Lifetime factory warranty. - CALIBER .223 REM/5.56MM NATO - MAGAZINE (1) 30rd capacity - BARREL 16" M4 Profile w/ A2 Flash Hider - HANDGUARD 15" KEYMOD - TRIGGER Mil Spec - STOCK Mil Spec 6 position collapsible
