Question: Just picked up my new ruger 10 22.  Noted that only two of the four holes line up with receiver....is this by design or did I order the wrong base ?
Document: Mounted with no difficulty on my 10/22 receiver. Don't install it backward, only two of the screw holes will line up. Fit Weaver Quad Lock Rings perfectly.
Unit arrived with two screws missing. Weaver mailed me 2 screws about a month later. Fit and function is perfect for a 10/22. Screws supplied do not penetrate through the bottom of the receiver, so there are no interference issues with the bolt/action. Well done Weaver.While waiting for the screws to arrive, ordered a second unit from Amazon. When screws arrived, I applied for a refund for the second order. They refunded without requiring me to return the second unit.
High quality Weaver base mount all holes line up exactly with factory pre-drilled Ruger reciever holes. All you need to do is remove the factory set-screws and install with the screws supplied. You can add a drop of locktite to the screws for the pro touch.
The mount mates flush atop the receiver and the mount holes line up with the pre-drilled receiver holes. The supplied screws are properly threaded for the receiver.
this is a better quality base than the one that Ruger ships with new 10/22 rifles.good deal for the money
I picked up one of these because I wasn't sure if my 10/22 came with a base (which it did). I actually like this one better then the ruger one, has more adjustment options and really looks a lot better. Great upgrade for a 10/22.
The holes line up on the 10/22 I put it on. It works well for red dot scopes that do not sit level on the regular rail due to the grooves not lining up with the attachment hardware. This allows the red dot to be mounted level rather than canted.
Can't think of a single downside to this product. I bought it intending to mount a scope on my 10/22, but used it sooner than expected when I found a deal on a cheap red dot at a big box store. The rail has a good weight to it and feels well-made. The bottom of the rail and the screw holes fit perfectly on the receiver. With a bit of blue threadlocker on the screws the rail mounted beautifully and won't be going anywhere.
For the cost you can not go wrong. I would not waste my money on really expensive ones. I mounted this on my new target 10 22 and it worked GREAT. I am so glad I did not spend $20-30. I dont see how they could be that much better. I am an extreme shooter with very high standards and this met them for very little cost.
Nothing special. Lost my original base for my 10-22 so had to get a new one. This works just fine
Answer: yes
