Fits Ruger 22/45 Mark III perfectly, super easy to install, great looking
Fits my Ruger 22/45 Mark III perfectly. Super easy to mount. Extremely nice finish. As others have noted, lets you mount on your Ruger without removing the rear sight. I put a red dot on my Mark III and am now shooting 1/2 groups at 25 yards with the gun. Since the gun is a bull barrel anyway, adding the small weight of the mount and scope does not affect the balance of the gun at all. Great product at a really low price.

Great product.
As with all Ruger branded items it was great! No defects or design flaws. Fit perfectly and allowed position choices for personal preference. Of all available, the factory one is the one to buy.Verified purchase: YesCondition: New

Very nice rail, maybe better than aftermarket options
The fit is factory perfect and the two mounting options (you can change front/back facing to extend rail forward or back) is ideal and the 2 cut-outs for the ejection port is a nice feature. I use a longer Volquartsen rear sight so this rail needed to be shortened at the back but that is a simple 5 min job with a file (and re-blacken the now cut end with Birchwood Casey anodize, black paint, or magic marker) as that edge doesn't show when butted up against rear sight. This lets you still use the iron sights.Verified purchase: YesCondition: New

Sits a little high on receiver.
Fits Mark IV 22/45 perfectly. Can be mounted in front of rear sight but extends over the barrel. Covers entire receiver with rear sight removed. May not have enough downward travel on rear stock sight if your not using a red dot.Verified purchase: YesCondition: New

Interesting design.
Perfect fit for my MkIII 22/45. The way the holes are drilled can go one of 2 ways. One way is in front of the rear sight. Other way goes over the rear sight dovetail if you want to remove the rear sight.Verified purchase: YesCondition: New

Good, solid rail
Have now mounted a Dagger Defense reflex sight on my Ruger Mark IV. Makes a good solid platform for a slightly heavy sight being used on a pistol. Good product.Verified purchase: YesCondition: New
