Integrated short M1913 Picatinny rail sections at the fore of the rail in the 3, 6, and 9 o’clock positions provide ready-to-use mounting space, while maximum venting helps dissipate heat and reduce overall weight. Magpul M-LOK attachment points are provided at the 3, 6, and 9 o’clock positions as well as the upper 45-degree quadrants for a highly modular setup.\u003c\/p\u003e\n\u003cp\u003eThe SMR MK4 includes Geissele’s proprietary 2.25\" long barrel nut to increase receiver interface surface contact for improved straightness, accuracy support, and zero repeatability during disassembly and reassembly.
