Williams Gunsight Co. Ace In The Hole Scope Base Set Ruger 10/22 w/Fiber Optic Front Sight

The Williams Gunsight Co. Ace In The Hole scope base set is a dedicated mount and backup-sight system built specifically for the Ruger 10/22 rimfire rifle. It pairs a Picatinny scope rail with an integrated rear aperture sight in a single low-profile design, so you can run a primary optic on top while still having co-witnessed iron sights ready if that optic ever goes down.

The base is CNC machined in the USA from high-grade aluminum and finished in black for a lightweight, rugged platform that clamps directly to the factory 10/22 receiver. The Picatinny rail accepts any standard Picatinny or Weaver-style optic, and the integral rear peep features a 3/8" x .093" aperture that is fully adjustable for windage and elevation, with interchangeable aperture inserts so you can dial in the sight picture you prefer.

A red fiber optic front sight (FireSight) is included, delivering a bright, high-contrast aiming point in any lighting condition. With the fiber optic front sight and adjustable rear aperture co-witnessed through the optic, the Ace In The Hole keeps you on target even when your primary scope is unavailable - a true "ace in the hole" for plinking, range sessions, hunting, or field use.
