This quality swivel clamp was machined precisely to hold a ring sight in place. Most machine shop clamps are made to hold gauges, etc. and can't take the high torque that your sight goes through with random bumps and knocks. This clamp has a semi circle binding ring that ensures maximum holding power. Because it is aluminum it will not rust.
The new and improved design replaces the old knurled thumbwheel with a low profile Allen screw. This makes the clamp less likely to snag a line during an unstable deployment. The clamp comes with an Allen wrench for your toolkit. (A picture to the left shows the Schumacher Articulating Ring Sight Bracket, Schumacher Swivel Clamp, and Brent's Cross Sight. Sold separately.)
Please Note: This is a 1/4" X 6mm Swivel Clamp and is meant to be used with any 6mm ringsight and any 1/4" Mounting Post or No. L1365 Schumacher Articulating Ringsight Bracket. Sold separately.
