Vortex HS 1 Inch Quick Release Pair of Rifle Scope Rings not only securely hold your scope to your rifle, they also allow you to attach and detach the scope without a loss of zero. These efficient Vortex rifle scope rings utilize a unique, lever-activated quick release mechanism that allows you to detach the scope at will, then reattach it with only a 1/4 MOA margin of error. These rings add incredible versatility to your hunt. The Vortex HS Quick Release Sintered Steel 2-Pack Scope Rings mount to your rifle scope using four T-15 Torx-style socket cap screws, which will securely hold your scope in place in the rings. Vortex has also equipped the rifle scope rings with a square recoil control key that will ensure a non-slip, positive recoil surface that can withstand bursts from the heaviest caliber rifles. And with a durable DuPont powder coat black finish, these rings will blend in with the rest of your hunting equipment. A pair of scope rings come in each package. With a pair of Vortex HS 1in Lever Release Riflescope Rings, you'll get a secure, quick release mounting platform for your professional-grade rifle scopes.
