The ST-324C is a S.O.A.R. *Shooting Optics and Rifle* Series tripod. The ST series carbon fiber tripods with their built in 30mm ball head makes for the lightest tripod in Leofoto’s S.O.A.R offerings. The lock lever controls the clamp and ball, easy and fast. The clamp on the ball head features a 2-size clamp, which can accept both Arca standard plate and gun rail. The clamp system is designed for rapid lock of guns and the 5mm diameter steel pin that engages 5.5mm diameter holes in the rail ensures the stability of the clamp.
