I have an early RRA NM upper with less than 2500 rounds through it for sale for $300. It has the slanted 1/2 minute sights, not the newer hooded peepsight model. Bolt, carrier and T-handle not included. I picked up 2 CLE uppers in the last 2 years and don't use this anymore. Excellent shooter, and in good condition with a few very faint scratches on barrel. Shipping not included. For Paypal, add 2%.
