Monstrum Ruger 10/22 Picatinny Rail Mount for Scopes and Optics

Fit perfectly on my 10/22 and works perfectly!!

Excellent product at a good price point. Fits my 10/22 perfectly just as I expected from Monstrum.

Looks good and sturdy construction. Lets my scope hold zero, even when I bump it getting it in and out of my crowded safe.

Good quality and fit. The screws provided were incorrect thread fo my Ruger 10/22 but I was able to re-use the original screws.

Fit on my Ruger 10/22 without issue. It was easier installing this than taking the weaver rail off. Red dot fit without issue. Now together scope mounts for the scope which will live on the rifle.

Selected this rail based on it's finish. Bought for my new ruger 10-22 carbine with the black synthetic stock. Other rails that I looked at either listed a "tactical" or "matte" finish. In other words the flat, dull black finish popular on many new firearms. Mine has that somewhat shinny blued finish. This rail matches well. Slightly less "shinny", but not a stand out difference. Also matches the optics that I installed. I stripped down the receiver before installing. This both allowed me to assure that the screws that were included did not protrude into the receiver/proper length, as well as assuring that the purple threadlocker I used ( yes they make a purple, also bought from amazon) did not leak into the receiver. That last part is why ruger states not to use a threadlocker when mounting rails(goodies). I used the low strength purple as the screws are tiny, under 1/4" in diameter, and going into aluminum. OK rail came with an extra screw. I only used the 4 needed, I now have an extra, just in case. No problems with the screws, I just used a good quality driver from my firearms rated set. Have taken this rifle out to the back 40 this week end. Fired OH about 500 rounds from a bulk brick, 100 CCI mini mags. All good/ no issues. All in All happy with purchase.

Idk what people are complaining about. This has worked flawlessly. Screws correct size and all holes line up.

Bought this picatinny rail to mount a thermal scope on my Ruger 10/22. Fit right on and scope fit nicely.

Mounted up perfectly!

Bolted right up without any issue to 2025 model 10/22. Great fitment

Sent with the wrong size screws, but otherwise seems like a good rail mount. Real metal with good paint and sturdy robust manufacturing. Hoping to get my issue resolved

Fit well

Nicely machined however the screws are too big and do not fit, now I have to source 6-48 screws with a big enough cap head.
