These Custom G1 Contender and SSK-50 Upgraded M4 Style Telescopic stocksets have been custom dipped in Kryptek TYPHON Camo and the mil-spec buffer tube has been Cerakoted to match by Brett at RIP, as well as upgrading the butt pad to a Mission Tactical model. They are an answer to an ongoing problem in the G1 Contender world, a shorter length of pull (LOP) for smaller shooters, younger shooters and lady shooters. that want to use the G1 Contender rifle platform. The LOP is approximately 12 1/2" adjustable up to about 15 1/2". They are very comfortable to shoot and come with the frame bolt, AND for the guys that like the tactical look they accomplish that as well. They will fit on any G1 (1st generation) Contender frame (not G2) made by Thompson Center AND SSK-50 frames as well. In addition they come with a matching forend (with hardware).
