Question: Bought K-31 clamp on mount and need rings for 1" scope.  K-31 dovetail is 1/2 inch on top.  I assume a 3/8 dovetail is what I need!Help!
Document: These rings fit my GAMO Bull Whisper Extreme very well. I took off the auxiliary rail and mounted them directly on the guns 3/8 in. rail. They are very stable after a little fix. There is almost 1/2 inch clearance for the lenses and lens covers of the 3-9 40mm AO GAMO scope that is OEM with this gun.My only complaint is the hex wrench that came with it doesn't fit the screws as well as it should.And my only other complaint is that there is no stop pin on the bottom of either mount.
After reading a few other reviews about people using these for the mosin nagant, i decided to give it a try. Basically you have to knock the rear site off the nagant and underneath there is an 11mm (3/8") dovetail. These rings mount to it perfectly. I put the ncstar pistol scope 2-7x in the rings and mounted it up. After a few range sessions, the site is still holding center nicely and the rings havn't budged. I did use loctite blue on the base mount screws as I saw it recommended in another post.
Great to use to connect a 1&#34; scope to a 3/8 inch rail. It was very easy to install. Love it.
I wanted these because it has four screws on the top and two on the bottom so it stays put as expected. I got this for my Mosin and now I wish I had gotten shorter ones. I have a 42mm scope and you can go with 3/4&#34; risers instead of the 1 inch like I got.
If you have a 30 mm scope typically your mounts will need to be changed, so scope doesn't touch gun. These worked spectacular on a BSA 40 mm scope, attached to a gamo air rifle. There was at least 3/8 if not more clearance of scope to barell of gun, I know it can handle a 50mm too, and probably up to 60. Ideal for Gamo dovetail mount with 40mm scope.
I underestimated these scope rings because I thought it was too good to be true. I went to local sporting goods and they do not have the 3/8 dovetail scope rings. They fit perfectly and it accommodates my 1 in. scope. However it may seem to have more usage with pellet guns, which I use, is also a plus on using more high powered scopes instead of the regular crosman spotting scope.
I purchased these mounts for my mosin nagant 91/30. I had to remove the rear sights with a hammer and punch to get to the 3/8 dovetail underneath. Mounted this ncstar pistol scope -NcSTAR 2 - 7x32 mm AO Pistol Scope. I couldn't be happier! I have fired 15 rounds through it so far and its still holding a zero. A must have for a mosin with a long eye relief setup. Buy it!
I needed dovetail rings to mount on my Crosman Phantom. They were better than the original rings and the one ring even has a small point on the bottom, which adjustable with the hex wrench, and is made to fit into the hole on the rear of the barrel to secure it and to avoid sliding. They look great and hold very securely. They were plenty high enough to house my Ncstar 3-9x40 scope which I also bought on Amazon:3-9X40 Black Scope/Ruby Lens/RingIf you're looking to buy either the rings or the adapter I recommend these since they are cheaper and are also high enough to mount a 50 mm.
Bought these for mounting a pistol scope on the rear sight base of the Mosin Nagant. You need the taller mount rings so that the scope fits. These work. I used a torx screwdriver instead of an alan wrench to tighten it down.
Solid built, fits 3/8 dovetail on Marlin receiver. Very tall, would call them extra high rings. Much better then the $9 rings at WM.
Answer: yes
