These rails are purpose-built and feature integrated short M1913 picatinny rail sections at the fore of the rail in the 3, 6, and 9 o'clock positions. Maximum venting for heat dissipation also dramatically reduces the rail's overall weight, while maintaining its same strong and rigid platform. It utilizes Magpul's M-LOK technology at the 3, 6, and 9 o'clock positions, as well as the upper 45 quadrants. The SMR MK4 is both versatile and modular, allowing the user to tailor their platform to his or her unique needs. The SMR MK4 also features Geissele's proprietary 2.25\" long barrel nut. This increases the surface contact where the rail interfaces with the receiver and creates a platform that can be trusted to be straight and true the entire length of the free float rail. This increases accuracy and zero repeatability during disassembly and reassembly when performing maintenance. Requires a Geissele barrel nut wrench for installation (sold separately).\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\n\u003cul\u003e\n    \u003cli\u003eHeight: 2.4 \"\u003c\/li\u003e\n    \u003cli\u003eInner Diameter: 1.35 \"\u003c\/li\u003e\n    \u003cli\u003eOuter Diameter: 2.11 \"\u003c\/li\u003e\n    \u003cli\u003eWeight w\/ Hardware: 13.5oz.\u003c\/li\u003e\n    \u003cli\u003eLength 13.5\";Includes Barrel Nut (Barrel Nut Wrench Sold Separately)\"\u003c\/li\u003e\n    \u003cli\u003eGeissele Automatics AR-15 13.5 Super Modular Rail MK4 M-LOK\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Information\u003c\/h3\u003e\n\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Geissele Automatics\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e GEISLE\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 854014005724\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e GEI05-278S\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\nInventory is synchronized directly with our distributor to help ensure current availability.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThank you for shopping with\n\u003cstrong\u003eTactical Storage Pro\u003c\/strong\u003e.\n\u003c\/p\u003e","brand":"Geissele Automatics","offers":[{"title":"Default Title","offer_id":47531316248747,"sku":"GEI05-278S","price":375.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/6373\/9819\/files\/GEI05-278S_1.jpg?v=1785384827","url":"https:\/\/tacticalstoragepro.com\/products\/geissele-automatics-geissele-13-5-spr-mod-mk4-mlok-ddc-gei05-278s","provider":"Tactical Storage Pro","version":"1.0","type":"link"}
