Make-up & Monsters Studios, under their ‘Apemania – A tribute to Planet of the Apes’ line, has produced a limited number of tribute stocks based on the gorilla carbine featured in the 1968 film ‘Planet of the Apes’, fitted for a Ruger 10/22 receiver and barrel. Pretty damn cool, although that extended magazine well looks like it might make loading smaller capacity magazines a bit of a chore.
They also offer a tribute stock fitted for an M1 Carbine, based on the carbine featured in ‘Beneath the Planet of the Apes’.
