The JE Machine Tech USA Made Blue 15" M-LOK Free Float Slant Cut Handguard & Upper Parts Combo offers an innovative blend of M-LOK and picatinny features, ensuring versatility and performance. Crafted from durable Type II black anodized 6061-T6 aluminum, the handguard includes four picatinny mounting points at the front for easy accessory attachment while maximizing the M-LOK area for weight reduction and improved ergonomics. The clamp-on system simplifies installation without requiring barrel nut timing. This combo also includes a standard AR-15 charging handle, a reliable dust cover, and a mil-spec forward assist kit, making it an exceptional choice for AR enthusiasts.Conceived to be an intermediary option between M-LOK and picatinny, the G style handguards are the perfect marriage of old and new. Starting from the front we kept four picatinny mounting points to allow the user the option to direct-attach accessories. Moving back, we removed the bulky picatinny and replaced it with M-LOK mounting points. This swap allows us to maximize the available mounting surface while reducing weight. In addition, the mid-M-LOK mounting surface slims the overall profile on the handguard while increasing ergonomics and comfort. At the rear of the handguard, you will find a pair of quick detach mounts and our clamp-on system. This system nullifies the need to time the barrel nut during installation, making the G style handguards the perfect option for users transitioning to M-LOK. 15" Handguard: Clamp-on system, no timing required for easy installationType II black anodized 6061-T6 aluminumFull picatinny rail on top and fixed picatinny rails at 3, 6, 9 o'clock positions near the frontSmooth middle for an ergonomic grip2 built-in QD socketsSteel barrel nut and all mounting hardware included1.357" IDWeight: 15"-17.20oz Charging Handle: Standard AR-15 charging handleMachined from 6061 T6 aluminumAnodized finishWeight: ~ 1 oz Dust Cover: Ejection Port Cover DoorSteel SpringSteel RodC-ClampReplaces your missing or damaged Ejection Port Cover on your AR-15 RifleWeight .05lb Forward Assist: Mil-Spec AR-15/AR-10 forward assist kitFeatures a tool steel forward assist pawl and press fit/pinned capIncludes forward assist assembly, spring, and installation pinWeight: < 1 oz
