Availability: In Stock
The Geissele Automatics Mk4 10.5'' M-Lok Super Modular Rail in DDC is a lightweight handguard built for shooters who refuse to compromise on modularity or performance. This M-Lok rail system delivers the rugged, rigid platform Geissele is known for while keeping weight to a minimum—critical on a short-barreled setup where every ounce matters. Whether you're running a defensive carbine, a precision 300 BLK build, or a compact hunting rifle, the Mk4's integrated design and extensive accessory mounting options let you dial in exactly the configuration you need without excess material dragging your gun down.
The Mk4 combines integrated M1913 picatinny rail sections at the 3, 6, and 9 o'clock positions with M-Lok slots across those same positions plus both upper 45-degree quadrants. This hybrid approach gives you quick access to standard picatinny-mount optics and lights up front while preserving M-Lok modularity for the rest of your build. The aggressive ventilation throughout the rail body does double duty: it sheds heat during sustained fire and slashes weight compared to solid aluminum designs, making it an ideal choice for shooters building lightweight combat or hunting rifles where every tenth of a pound adds up.
Built from durable aluminum and finished in Geissele's Desert Dark Earth (DDC) color, the Mk4 10.5'' fits mid-length gas systems and most 10.5'' barreled uppers. The rail clamps to your receiver via a proprietary barrel nut system (barrel nut wrench and gas block sold separately). This is a no-nonsense rail for builders and shooters who understand that good gear should work hard and weigh light.
