Fostech 6202-OD: New from Fostech these are the highly anticipated ultra-light, ultra-strong, proprietary alloy stripped upper receivers from Fostech Arms. Fostech's AR-15 upper receiver is 35% lighter than standard uppers on the market today while also being one of the strongest and most rugged uppers in the market. Not satisfied with being just the lightest upper on the market Fostech has reinforced key areas of the upper making these tougher than nails. These have a beautiful smooth finish and look and work great with any AR-15 lower but are a perfect companion to the Fostech lower. This particular model features an OD Green Finish and comes complete with forwarding assist and ejection port cover.
