Love 22/45 Picatinny rail... but is improved by centered 6mm slot! 6/10/2021
Decided my 22/45 needed this rail from previous comments in reviews of this Pic rail. It quickly became obvious that, though very well designed for its intended use, the rail would be significantly improved by a 6mm wide slot cut along the centerline of the top rail to aid in sighting the pistol quickly and accurately. See uploaded photo of my Picatinny rail cut along the centerline with a 6mm/2-flute end mill set 2.9mm deep.

Picatinny rail 12/5/2020
Received and installed my Picatinney rail today. Nice aluminum part and it fits very well on my Mark IV 22/45. Seems to be a quality piece. For other folks purchasing this part you will need a 1/16 allen wrench to remove the 3 small countersunk screws and a 3/32 allen wrench to install the rail with the provided screws.

Rail mount for my Vortex 3MOA reddot scope is low. 6/8/2020
I bought this rail for my Ruger Mark IV. Installation was easy, Vortex 3MOA red-dot fits well. Everything shot dead center, but about an 1 1/2” low at 10 yards. I took the mount off, shot with iron sights again and it was center of the bullseye. I’m assuming a defect in the part. Not thrilled with my purchase through Ruger, for a Ruger gun.

Quality, simplicity, 7/31/2019
This will put a smile on your face. Fits like a glove. Goes on so easy. I would not hesitate to buy this part again for my next Ruger pistol.

Versatile Rail 3/12/2017
This Picatinny rail can be mounted two ways: 1. in front of the rear sight and extending past the barrel/receiver junction leaving the rear sight in place or 2. removing the rear sight and installing it so it completely covers the rear sight dovetail and ends just at the receiver/barrel junction. Mounting holes and ejection port reliefs are provided for both orientations. This versatility allows you to use both long sights like the C-More Railway and still use the Black Dog Holster with the rail mounted.

Just what I needed 1/31/2017
I needed a picatinny mount for my Vortex Venum red dot. The local stores were suggesting any mount that fit the holes and found one that would have required removing the rear sight which isnt what I wanted. Ruger to the rescue....this rail was exactly what I needed. The holes aligned perfectly and didnt require removal of the rear sight. Just what I wanted!

WELL MADE BUT! 1/24/2017
Appears to be a quality part with one exception. The channels are cut to slightly less than the low limit for depth. Some mounts are not going to sit down far enough making them unstable.
