Your riflescope will stay securely in place on your gun with this set of Scope Rings with Q-LOC Technology from Trijicon. Designed for scopes with objective lenses up to 44mm, the 6061-T6 aluminum rings mount on a Pictinny rail with one hand and with no tools required. The spring-loaded dovetail exerts 12-16 inch-pounds of torque—enough to hold the ring in place and retain zero—even without tightening the knobs. (The knobs can be tightened to 30-38 inch-pounds.)
