Grovtec Keymod Forearm Adaptor - For Push Button Base

The Grovtec Keymod Forearm Adaptor – For Push Button Base (GTSW233) is a precision mounting solution designed for shooters who run push-button-equipped accessories on Keymod-slotted handguards. This adaptor bridges the gap between modern Keymod systems and legacy push-button bases, eliminating the need to replace established optics, bipods, or vertical grips. Born from the evolution of tactical rail systems, this adaptor serves military, law enforcement, and civilian operators who demand compatibility without compromise.

Manufactured by GrovTec with a durable black-oxide finish, the adaptor provides corrosion resistance and professional aesthetics across duty and range environments. The black-oxide process hardens the steel surface, ensuring longevity under hard use and in variable weather conditions. Weighing only 0.1 pounds, this compact adapter (2.85 x 1.15 x 4.85 inches) adds negligible weight while maintaining rigid, zero-shift mounting geometry—critical for optics, lights, and bipod stability.

Operators upgrading to Keymod handguards without retiring proven push-button accessories will find this adaptor indispensable. Installation is straightforward: the adaptor mounts directly into Keymod slots, then accepts standard push-button bases, restoring full compatibility. Ideal for AR-pattern rifles with Keymod-equipped fore-ends, this solution is particularly valuable for those running magnified optics or precision bipods that rely on push-button attachment points. No tools beyond a standard push-button base installation are required, making field reconfiguration practical and seamless.
