Perfect for Hunting, Plinking, Target Shooting and Defense .
 The "One Hole" sight will provide you with a quick, positive sight picture for those tough close, shots where both time and range are short. And when that Big Buck you've been chasing all season just won't come any closer, you will have the tools and confidence to take that long-range shot you would once have passed up.

It' all good news!
 This aperture sight blade is faster on target at all ranges and is fully adjustable just like your factory blade, but better. These sights carry easily and will fit in your holster with little or no modification, it does not add the weight and bulk of a scope and you don't have to worry about it shooting loose or flying over your shoulder when you pull the trigger. This sight works and we build them tough
Added Vertical Adjustment
 We redesigned the "One Hole" sight blades to have more vertical adjustment than the standard blades... you can lower your point-of-aim up to 12" at 100yrds, so you won't be shooting high with heavy loads

We designed the "One hole" sight for heavy field use.
 Built from high quality, medium carbon, Cold Rolled steel. Then MilSpec Flat Black Phosphate plated to reduce glare and provide an attractive and durable weather resistant finish.

Each RUGER "One Hole" set Includes 2 Sight Blades .
 One blade with an aperture of 7/32" and one blade with an aperture of 9/32".

After much testing, tuning and lots of shooting, we have found that the 9/32" blade is best where
the shooting is likely to be close and fast. The 7/32" blade is best on open ground, in a tree stand, or on the range at 30 yards or more.

Highlighting the front sight will make it easier for your eye to pick up the sight quickly, and helps you to score fast and accurate hits at all ranges. Try a little sight paint or nail polish applied to of the front sight (White nail polish works well for me).
