{"product_id":"pts-kinetic-scar-mrex-mlok-mk2-425-rail","title":"SCAR MREX M-Lok MK 2 4.25\" Rail","description":"\u003cp\u003eThe FN SCAR’s factory rail system is notoriously bulky, uncomfortable to grip bare-handed, and forces tactical accessories high off the receiver axis. Standard extended rails add support length, but leaving full-length Picatinny along the top spine adds unnecessary weight and creates snag points for slung gear.\u003c\/p\u003e\n\u003cp\u003eOfficially licensed by Kinetic™ Development Group, the PTS SCAR MREX™ MK2 4.25” Rail completely overhauls your rifle's front-end geometry. Precision machined from 6000-series aluminum, it weighs just 192 grams while providing a massive 4.25-inch extension forward of the front sight\/gas block. The MK2 configuration eliminates the top 12 o'clock Picatinny rail entirely, replacing it with continuous M-LOK slots. Combined with added M-LOK positions at 2 o'clock and 10 o'clock, you can tuck tactical lights and IR illuminators closer to the barrel bore than ever before, creating an ultra-clean, low-profile setup tailored for a modern C-clamp grip.\u003c\/p\u003e\n\u003ch6\u003eKey Features \u0026amp; Technical Highlights\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eReplaced 12 O'Clock Picatinny with Full M-LOK: Strips away bulky 1913 rails on top to create a flat, continuous M-LOK channel for lower-profile switch and optic\/laser mounting.\u003c\/li\u003e\n\u003cli\u003eExtended 4.25\" Real Estate: Adds over 4 inches of support space past the gas block, accommodating extended arm reach for faster target indexing and muzzle control.\u003c\/li\u003e\n\u003cli\u003eMK2 2 \u0026amp; 10 O'Clock M-LOK Channels: Added angular mounting slots allow weapon lights to sit tight against the gas block shield, reducing broadside snag risks.\u003c\/li\u003e\n\u003cli\u003eOne-Piece 6000-Series Aluminum Construction: Delivers rugged durability for hard field use while keeping added front-end weight down to only 192g.\u003c\/li\u003e\n\u003cli\u003eIntegrated Anti-Rotation QD Mounts: Built-in sling sockets on both sides keep two-point slings from twisting or wrapping under high movement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eTechnical Specifications\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: PTS Syndicate (Fully licensed by Kinetic™ Development Group)\u003c\/li\u003e\n\u003cli\u003eProduct Name: SCAR MREX™ M-LOK™ MK2 4.25” Rail\u003c\/li\u003e\n\u003cli\u003eSKU \/ Part Numbers: KN013490307 (Black) \/ KN013490313 (Dark Earth)\u003c\/li\u003e\n\u003cli\u003eMaterial: 6000 Series Aluminum  \u003c\/li\u003e\n\u003cli\u003eDimensions: 284 (L) x 55 (W) x 54 (H) mm  \u003c\/li\u003e\n\u003cli\u003eWeight: Approx. 192g  \u003c\/li\u003e\n\u003cli\u003ePlatform Compatibility:\n\u003cul\u003e\n\u003cli\u003eCyber Gun SCAR-H (GBB)  \u003c\/li\u003e\n\u003cli\u003eVFC SCAR-H (AEG \u0026amp; GBB) \/ SCAR-L (AEG)  \u003c\/li\u003e\n\u003cli\u003eTokyo Marui Recoil Shock SCAR-H \/ SCAR-L  \u003c\/li\u003e\n\u003cli\u003eARES SCAR Series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eOperational Applications\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eMid-to-Long Range SCAR Builds: Perfect extension for standard-length barrels, providing optimal hand-placement ergonomics without ruining weapon balance.\u003c\/li\u003e\n\u003cli\u003eSleek Low-Profile Accessory Rigging: Mount pressure pads and lights directly to top\/angled M-LOK slots without needing tall Picatinny adapters.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PTS Kinetic","offers":[{"title":"Black","offer_id":42226980454590,"sku":"KN013490307","price":920.0,"currency_code":"HKD","in_stock":true},{"title":"Dark Earth","offer_id":42704112156862,"sku":"KN013490313","price":920.0,"currency_code":"HKD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/0368\/2494\/products\/KineticSCARRail-4.25-black-1.jpg?v=1754903894","url":"https:\/\/pts-steelshop.com\/products\/pts-kinetic-scar-mrex-mlok-mk2-425-rail","provider":"PTS Steel Shop","version":"1.0","type":"link"}
