• Free-floating design with monolithic top rail – The rail slides over the included proprietary barrel nut and locks securely against the receiver with six screws, creating a rigid, continuous top rail for reliable optic mounting.
• M-LOK compatibility – Versatile M-LOK slots on multiple sides enable quick attachment of accessories like lights, grips, bipods, and lasers without adding excess bulk.
• DPMS low-profile spec – Engineered to fit standard DPMS-pattern .308 receivers for seamless integration into existing builds.
