The newest member out of UTG PRO’s increasingly popular Super Slim rail family, MTU037SSM, boasts the same sleek design elements and ease of installation that has made its Keymod Compatible counterparts a huge success, but now features the exciting M-LOK™ system. The 17” extended length rail system is made in Livonia, Michigan from 6061-T6 aircraft grade aluminum and includes a slim octagonal profile, a Picatinny scalloped top rail, ergonomic groove cuts throughout the length of the rail, and 63 M-LOK™ slots on 7 tracks. An 8 slot M-LOK™ Picatinny rail section and QD sling swivel M-LOK™ adaptor are included in the package, making this system ready to go right from the start. Solidly Secured by UTG PRO’s innovative proprietary barrel nut locking system and integral anti-rotation tabs, a rock solid installation and a seamless fit is achieved. The shorter length 15” MTU019SSM and 13” MTU006SSM will be available concurrently providing to consumers various options to best suit their needs.
