Midwest Industries Combat Rail HD Features The Midwest Industries Combat Rail HD is machined from hard coat anodized 6061 aluminum giving the 9.25 inch handguard the strength needed to handle hard use without flexing or loosening over time. Its one-piece free float design keeps the barrel isolated from pressure that would otherwise affect accuracy a critical detail for shooters chasing consistent groups. Machined heavy-duty anti-rotation tabs keep the handguard securely indexed to the upper receiver preventing rotation under recoil or heavy accessory loads. The included 5-slot Picatinny rail section at 12 o clock offers minimal point of impact shift for night vision aiming devices a detail that matters for low-light and tactical applications. Seven sides of M-LOK slots run the length of the handguard giving shooters the freedom to mount lights grips slings and other accessories wherever they are needed most. A longer 4140 steel barrel nut adds strength at the critical junction between handguard and upper receiver while included Torx hardware simplifies installation. The rail ships complete with mounting hardware a barrel nut wrench and a 5-slot polymer M-LOK accessory rail for immediate use out of the box. Made in the USA the Combat Rail HD reflects Midwest Industries focus on small manufacturing details that improve the overall rifle platform for serious shooters.
