For sale is a brand new Adams Arms Tactical Elite piston upper with 11.5 barrel. It features a quad rail manufactured by Samson, adjustable gas block, melonite treatment all over. Upgrades: Troy claymore muzzle break Magpul afg 2 BCM ambi charging handle. Very low profile rubber rail covers. This is a new, unfired upper. Factory built NOT a kit. I have it on a pistol lower at the moment and the plan was to eventually run it suppressed. Piston upper are more reliable with short barrels and run cooler as well. I am selling it only because I have found a used motorcycle I really want to purchase This upper is worth more than 800 dollars with all the upgrades. I will sell for 650. I can post pictures later tonight or send via email. No trades on this one Thanks
