Six channels of Picatinny rail are machined at the 3, 6 and 9 o'clock positions alongside M-LOK slots, and the top rail runs unbroken from the receiver forward — so you can clamp a Picatinny accessory directly where you need it without giving up the slim, comfortable M-LOK profile everywhere else.\u003c\/p\u003e\u003cp\u003eIt is held to the receiver by BCM's patented combat rail lock-up (US Patent 8904691), which uses self-locking cross bolts applying centred force to align the handguard and hold that alignment through firing.

Accessories are M-LOK, or Picatinny clamped directly to the integral rail channels; KeyMod hardware does not fit.

Very little else gives you that much rail length for that little mass.

At 15\" and 17\" these are long tubes: they need a low-profile gas block and a barrel long enough that the handguard does not overhang the muzzle device, so measure from the receiver face to the muzzle before ordering. Fitting replaces the barrel nut with BCM's own, so it is an armourer's job rather than a slip-on swap.

Shorter tubes suit pistol- and carbine-length gas with a low-profile block; 10\" and 12\" cover mid-length systems.

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 — imported from the USA with all duties paid by us and dispatched tracked from the UK in 7–10 business days, with nothing to pay on delivery.\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":60873772040526,"sku":"BCM-MCMR-7-556-BLK","price":239.99,"currency_code":"GBP","in_stock":true},{"title":"8\"","offer_id":60873772073294,"sku":"BCM-MCMR-8-556-BLK","price":239.99,"currency_code":"GBP","in_stock":true},{"title":"9\"","offer_id":60873772106062,"sku":"BCM-MCMR-9-556-BLK","price":249.99,"currency_code":"GBP","in_stock":true},{"title":"10\"","offer_id":60873772138830,"sku":"BCM-MCMR-10-556-BLK","price":259.99,"currency_code":"GBP","in_stock":true},{"title":"13\"","offer_id":60873772171598,"sku":"BCM-MCMR-13-556-BLK","price":269.99,"currency_code":"GBP","in_stock":true},{"title":"15\"","offer_id":60873772204366,"sku":"BCM-MCMR-15-556-BLK","price":279.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1081\/3223\/7646\/files\/bcm-mcmr-m-lok-handguard-7-inch.jpg?v=1789880874"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1081\/3223\/7646\/collections\/ar-15-handguards.jpg?v=1790021624","url":"https:\/\/onyxarmaments.co.uk\/collections\/ar-15-handguards.oembed","provider":"Onyx Armaments","version":"1.0","type":"link"}
