VERY interesting ebay item! Have not seen one of these since the late 60's

Was browsing ebay items searching for Knights rail systems and happened upon this item for early Armalite Colt AR15 / M16... I havent seen this kinds of stuff for a longtime. This guy has some pretty interesting stuff! :dancingbanana: Just thought I would pass this along... 442nd
