Geissele MK8 Super Modular Rail 9.3″ M-LOK DDC

Description

The Geissele SMR MK8 Super Modular Rail is a free-floating handguard designed for AR-platform rifles. It uses Magpul’s M-LOK interface at the 3, 6 and 9 o’clock positions and the upper 45-degree quadrants to provide modular accessory mounting. Strategic venting at the lower 45-degree quadrants improves heat dissipation while reducing overall weight. The rail ships with Geissele’s proprietary 2.25-inch barrel nut to increase contact surface and maintain a straight, true mounting platform.
