WEAVER48276, Grand Slam Base, S460

No issues installing or using as a very solid base for mounting optics on a 10/22. These can be hard to find, so grab one if you need it.

Weaver Mount for 10-22As noted by others, all 4 holes in this Weaver mount do not line up with the 4 holes in the receiver. However, they do line-up with 2 of the holes, giving 4 possible positions, which is a good thing.Also, as noted by others the screws included with the mount may not match the size and thread of the holes taped in your receiver. The 2 cap screws I received are metric, M4-0.7, and both were the same length (8mm thread length and 11.68mm overall). They were a larger diameter than the holes in my 110 prefix 10-22. The proper screw for mine seems to be a #6-48 fine thread. Matching the thread length of the screws receives would be a 5/16”, but this is way too long, I went with 3/16” because even a ¼” was hitting the top of the bolt.And, remember; if you want to use a little “locktite” (not recommended in the Ruger Manual) remove the bolt first so you don’t gum something (like a firing pin) up.An improvement would be if it was low enough that you could still use your iron sights without having to remove it.

Excellent product for the money. Fit the receiver perfectly, however the slots running across the base are too narrow for the cross bolt on the quick release base on my optics. A little work with a round file was needed for a perfect fit, and touch up on the black finish. Still can't beat it for the price.

The Bushnell red dot packaging said it required a Picatinny Rail. Found the Weaver Multi-Rail worked perfectly to securely mount the Bushnell TSR-25 sight.

In the retail shops if you can find a good mount they are well over $15 each. This one sounded too good to be true, once again I am happy as to the value Amazon offers! Less than $7 shipped w/no tax!!! Being a Weaver product it is top quality. It is a bit longer than the factory rail but with many more slots for ease of set up. It works as intended, comes with screws and is simply the best value going. Very nice black finish. Five stars!

Perfect fit, easy install-made to easy to install scope and rings on my Stock Ruger 10/22

Machined very well, great for my 22. I tried to post this review several times but every time I include a photo of my gun it gets denied.Don’t sell gun parts or get less sensitive people to inspect your reviews Amazon.

This scope rail works just fine. I used a Barska Colorado 3-9x40 scope that came with scope rings. I think I would rather have a set of Weaver 1-Inch Steel Lock Mounts for Ruger 10/22 for the 10/22 because then i can use the iron sight as back up. with this current set up you cannot use the Iron sights,the Problem is that the Rail is high enough on the body that it blocks the Rear Iron site from view. with the See-through scope rings it eliminates the rail and mounts straight to the body of the gun. Of course there would be pros and cons of that method as well. Such as with those other mounts you have a harder time taking your scope off for cleaning or storage or whatever other reason you might want to take the scope off for. My iron sights were way off anyway so i don't really care about the iron sight so that's not an issue for me. But if you have a new rifle I recommend getting the See-through scope rings. they cost the same. No problems other than the iron sight issue. I think this just comes down to personal preference. I am giving it 4 stars because there is no problem and it works great. The set up took no time at all. just take out the filler screws off the rifle and screw in the ones that comes with the rail. great product. Nothing negative just and observation. A picture will make it clearer. I Hope I helped.

Excellent product. Gives you more mounting options than the standard rail that comes with the 10/22. Was unable to mount my dot sight with the factory rail as there were only a couple notches and they didn't line up with my rail. This made it better though.

Perfect fit and good quality

Does as advertised, however wish it came with thread locker pre applied.

It fit the gun with out any problems
