Ok I have a RRA AR-15 Operator 2... After reading the So you want to buy an AR-15 - FAQs thread I thought I throw some updates at this thread as far as RRA goes.. The thread linked above (p.4) the poster stated that the RRA has no M4 feed ramp WELL IT NOW DOES! He also stated that the Gas Key is not properly staked WELL IT IS NOW. Anyways I was just looking to update the RRA AR-15 status.. I will post pics soon!
