Top RIS Rail for SR2M GBB SMG Raptor TWI / Lambda Defence

Are you looking for a solid and elegant solution to equip your SR2M GBB SMG with a full-featured RIS rail for optics mounting? Do you need a part that preserves the original appearance while offering a robust solution for mounting a red dot sight? This low-profile RIS rail is designed for mounting red dot sights on the upper receiver of the Lambda Defence SR2M GBB. Thanks to precise manufacturing from a durable aluminum alloy and a weather- and wear-resistant matte finish, the rail maintains its looks and function even under intensive use. The rail does not disrupt the weapon’s silhouette and allows comfortable aiming even with optics featuring a low mounting base. Development in cooperation between Lambda Defence and Raptor TWI ensures precise compatibility and a secure, wobble-free fit. In addition, it faithfully reproduces the original ZenitCo model. When installing some wider optics such as XPS, 553, LCO, etc., the stock cannot be folded.
