IRT is all about replicating popular Russian gear with the old time material they were build in but with an affordable price tag. IRT have recently developed the RT-3, which is made in OD Advizent material and attaches to almost all AK platforms out there with 2 modes : single point and three point. Sling is length adjustable and the back loop is fastened with velcro so it should fit onto almost any stocks found out there in the market.
