DetailsThe BOBRO Quick Release Mounts are a premium upgrade for the SIG SAUER ECHO CV25 Thermal Clip On, offering enhanced versatility and a reliable mounting solution for your thermal optic. Designed with precision and durability in mind, these mounts feature both self-tensioning and self-biasing mechanisms, making them one of the most trusted options in the industry. Self-Tensioning Mechanism: Automatically applies the correct amount of clamping force to a Picatinny rail without the need for manual adjustments. The mount adapts to rail tolerances for a snug, secure, and repeatable fit.

The quick-detach system allows you to remove and reinstall the optic without tools and without the need to re-zero. Recommend torquing to 40-in lbs with blue thread locker. Please ensure that you remove any old thread locker before applying the new one. FEATURES: Available in 1.535", 1.700", and 1.930" height options. Anodized black finish.
