Geissele's ultra-modular MK8 rail system features M-LOK slots at 3, 6, and 9 o'clock positions plus upper quadrants. Vented design reduces weight while maximizing heat dissipation for serious shooters.
The MK8 represents Geissele's commitment to modularity and performance. This 15-inch rail system was among the first to fully embrace Magpul's M-LOK mounting standard, giving you unprecedented flexibility in configuring your rifle exactly as you need it.
