Nightforce customers love the fast magnification changes in all conditions provided by the threaded Power Throw Lever (PTL) that is inlcuded with many of our scopes. If your scope doesn’t include the threaded PTL, such as the NXS and SHV riflescopes, or you prefer a larger throw lever, our clamp on PTL will work perfectly. Machined from aluminum and annodized in the USA, the Clamp On PTL requires no modification of the riflescope to use.
