Bought the AR-12 brand new. Got it home...tried to rack a round into chamber, bolt stuck in open position. The weapon will not chamber a round. Tried calling Omega Arms company in Newark Ohio. Phone number doesn’t work. Tried emailing. Email does not work.I want my money back. These guns are absolute junk. Who ships a weapon from the factory that won’t even chamber a round? Shows the lack of quality, reliability and quality control.
