-Echo 3 Ordnance is discontinuing the AR10 line. All AR10 complete firearms and uppers will still carry our LIFETIME warranty after the line is discontinued.
-This is a clearance item. All sales are final and cannot be returned for any reason
-There is no industry standard for the AR10 platform. Not all brands work with each other. E3O uses a DPMS Gen 1 upper which is the most “common” pattern used.
