Product Description
The TNTE M4 URG RIS3 Upper Receiver Group features the Rail Interface System (RIS III), This two-piece, free-floating rail system allows the mounting of devices like a M203 grenade launcher without influencing the barrels harmonics, eliminating problems like wandering point of impact that plagued other mounting designs. The two-piece design also allows for partial disassembly of the rail to aid in cleaning around barrel without completely removing the entire rail system. The weight of anything attached to the RISIII rail system is fully supported by a sturdy bolt-up system, using 6 grade 8 bolts, leaving the barrel completely free floating for best possible accuracy and dependability.
