{"product_id":"bcm-mcmr-m-lok-handguard","title":"BCM MCMR M-LOK Handguard for AR-15","description":"\u003cp\u003eThe BCM MCMR is a free-float M-LOK handguard for AR-15 and M4 rifles, clamping to a mil-spec barrel nut and carrying a continuous 1913 Picatinny top rail.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFree-float rigidity, M-LOK where you want it, and nothing you do not need — the MCMR is the handguard BCM built around the shot, not the catalogue.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMCMR stands for M-LOK Compatible Modular Rail, and the name is the whole design brief. The tube is machined from 6061-T6 aluminium and hard-coat anodised to Mil-A-8625F Type III Class 2, then locked to a steel barrel nut by BCM's patented indexing and lock-up system (US Patent 8904691) so the top rail stays in line with the receiver rail under heat and under load.\u003c\/p\u003e\u003cp\u003eBecause it free-floats, nothing you bolt to the handguard touches the barrel. A bipod, a sling under tension, a hand pulled hard into a barricade — none of it deflects the barrel or moves the group. That is the single biggest accuracy return available on a UK straight-pull AR-15, where every shot is a deliberate, aimed shot and the rifle spends its life on bags, bipods and barricades rather than being run at speed.\u003c\/p\u003e\u003cp\u003eThe profile is slim — M-LOK slots sit at 3, 6 and 9 o'clock with an uninterrupted Picatinny rail along the top, so backup sights, night vision and lights index off one continuous plane. An M-LOK sling mount is supplied with the handguard.\u003c\/p\u003e\u003ch3\u003eWhy shooters choose the MCMR\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree-float tube\u003c\/strong\u003e — loads from the sling, bipod or support hand never reach the barrel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous 1913 top rail\u003c\/strong\u003e — one unbroken plane from receiver to muzzle for sights and night vision\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePatented lock-up and indexing\u003c\/strong\u003e — the top rail stays aligned under heat and recoil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix lengths, 7\" to 15\"\u003c\/strong\u003e — match the tube to the barrel and gas system you actually have\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight for its size\u003c\/strong\u003e — 4.8 oz (135 g) at 7\", 9.2 oz (260 g) at 15\", plus 2.3 oz (65 g) of hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat the MCMR fits\u003c\/h3\u003e\u003cp\u003eFits AR-15\/M4 upper receivers, including UK straight-pull AR-15 builds, and clears barrels up to 1.0\" (25.4 mm) in diameter. The supplied steel barrel nut replaces your existing nut, so the handguard is a barrel-off or at least a barrel-nut-off job — not a slip-on swap. Shorter tubes suit pistol- and carbine-length gas systems with a low-profile gas block; longer tubes cover mid-length systems and can be run over a fixed front sight base where the length allows. Measure from the receiver face to the gas block before choosing a length, because the handguard must clear the block, not sit on it.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePlatform\u003c\/th\u003e\n\u003ctd\u003eAR-15 \/ M4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eMil-spec upper receivers; barrels up to 1.0\" (25.4 mm) diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eFree-float M-LOK handguard with full-length 1913 top rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003e6061-T6 aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eHard-coat anodised, Mil-A-8625F Type III Class 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e7\" 4.8 oz (135 g) · 8\" 5.3 oz (150 g) · 9\" 5.9 oz (165 g) · 10\" 6.6 oz (185 g) · 13\" 8.2 oz (230 g) · 15\" 9.2 oz (260 g); mounting hardware 2.3 oz (65 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003ctd\u003e7.39\" (188 mm) · 8.14\" (207 mm) · 9.4\" (239 mm) · 10.5\" (267 mm) · 13.4\" (340 mm) · 15.0\" (381 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount interface\u003c\/th\u003e\n\u003ctd\u003eM-LOK slots at 3, 6 and 9 o'clock; continuous 1913 Picatinny top rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eBravo Company USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMPN\u003c\/th\u003e\n\u003ctd\u003eBCM-MCMR-7-556-BLK · BCM-MCMR-8-556-BLK · BCM-MCMR-9-556-BLK · BCM-MCMR-10-556-BLK · BCM-MCMR-13-556-BLK · BCM-MCMR-15-556-BLK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eGive the barrel room to shoot. \u003cstrong\u003eOrder the MCMR today\u003c\/strong\u003e — in stock at Xtreme Tactical Gun Parts with free tracked UK delivery in 7–10 days.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eExplore more:\u003c\/strong\u003e \u003ca href=\"\/collections\/m-lok-accessories\"\u003eM-LOK Accessories\u003c\/a\u003e, \u003ca href=\"\/collections\/ar-15-parts-accessories\"\u003eAR-15 Parts \u0026amp; Accessories\u003c\/a\u003e or browse all \u003ca href=\"\/collections\/bravo-company-usa\"\u003eBravo Company USA\u003c\/a\u003e.\u003c\/p\u003e","brand":"Bravo Company USA","offers":[{"title":"7\"","offer_id":42843549761616,"sku":"BCM-MCMR-7-556-BLK","price":239.99,"currency_code":"GBP","in_stock":true},{"title":"8\"","offer_id":42843549794384,"sku":"BCM-MCMR-8-556-BLK","price":239.99,"currency_code":"GBP","in_stock":true},{"title":"9\"","offer_id":42843549827152,"sku":"BCM-MCMR-9-556-BLK","price":249.99,"currency_code":"GBP","in_stock":true},{"title":"10\"","offer_id":42843549859920,"sku":"BCM-MCMR-10-556-BLK","price":259.99,"currency_code":"GBP","in_stock":true},{"title":"13\"","offer_id":42843549892688,"sku":"BCM-MCMR-13-556-BLK","price":269.99,"currency_code":"GBP","in_stock":true},{"title":"15\"","offer_id":42843549925456,"sku":"BCM-MCMR-15-556-BLK","price":279.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/4978\/1328\/files\/bcm-mcmr-m-lok-handguard-7-inch.jpg?v=1786504396","url":"https:\/\/xtremetacticalgunparts.co.uk\/products\/bcm-mcmr-m-lok-handguard","provider":"Xtreme Tactical Gun Parts","version":"1.0","type":"link"}
