The Geissele Automatics Super Modular Rail MK14 transforms AR platform rifles with precision-machined aluminum construction and advanced M-LOK attachment system. This 15-inch free-floating handguard delivers enhanced accuracy potential while providing extensive modularity for accessories and optics mounting.
What Makes This Different
Geissele's proprietary barrel nut system creates a rock-solid platform that eliminates deflection under heavy use. The MK14's continuous top rail extends receiver height across the entire length, maintaining consistent sight plane for optics mounting. Internal anti-rotation tabs and precision tolerances ensure zero shift during rapid temperature changes or sustained fire.Key Features
