The Glock pistol design was not the first to incorporate a plastic frame. Heckler & Koch used polymer for their VP70 pistol frame in 1970.[11] HK's innovation of polymer frames and polygonal rifling seem to have been influential in the Glock design. Still earlier, Remington introduced their polymer-framed Nylon 66 Rifle in 1959. This was so revolutionary at the time that Remington dyed the plastic brown to resemble wood and fitted a cosmetic sheet-metal cover on the receiver to make it appear to be made from steel. Further, the most extensive use of polymers in a pistol was in the Ram-Line Syn Tech Exactor pistol with a barrel made from steel-lined plastic.
