DetailsThe BOBRO Quick Release Mounts are a premium upgrade for the SIG SAUER ECHO SV35 & SV50 LRF THERMALS, offering enhanced versatility and a reliable mounting solution for your thermal optic. Designed with precision and durability in mind, this mount features 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. Self-Biasing Mechanism: Ensures the mount consistently aligns in the optimal position on the rail, maintaining a solid and repeatable point of contact for reliable performance. These features help ensure your thermal optic won&&';;t shift or lose zero due to recoil or environmental changes. 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: Quick release functionality Factory heightAnodized black finish.
