Fostech Tiger Tungsten: Here is the newest production run from Fostech! This pistol features Fostech Lite Upper and lower in their beautiful tungsten finish with a matching 10.5″ Mach 2 handguard with a partial rail toward the front of the handguard for sight mounting. The 10.5″ Faxon barrel is tipped with an A2 flash hider and is complemented nicely by a black nitride BCG. A tailhook brace and Sabre grip round out the package as far as furniture while Fostech includes one of their 30 round magazines with a Yellow Fostech band at the base. The most important part of this package, however, is the AR-II Fostech Echo binary trigger that comes installed from the factory.
