New rifle build-Optic Mount issue - SOLVED

[Major Sights]

So I am building a new "tuned" rimfire rifle that will be used for some upcoming Mapleseed shoots as well as for the pure joy of having a pimped out rifle that I can afford to shoot.


I have a Leupold STD scope mount for this Ruger rifle and some low 1" rings. I also have a new Bushnell AR optics 3-9x40 scope I got for this rifle. However the Bushnell scope has a little protrusion out the bottom left side that allows the side parallax adjustment to work, but it interferes with the scope ring base and am unable to get the scope level to the rifle. The mount has already been factory thinned on both the left and right sides, but for this to work I either need a new mounting solution or dremmel the one side at the best location for eye relief on a 45degree angle to allow the protrusion to fit and apply some paint. If this were for a full power caliber rifle I wouldn't consider doing custom work on the mount, but it being a $30 OSTS closing special on a .22lr I kind of wanted to use it. Another reason to use it would be the height over bore is almost as low as you can go before fleas would need a haircut to pass thru between the eye bell and the receiver.

So what say you? Dremmel the mount, or find a new solution?

A good hand file may be able to be a bit more precise without taking off to much material.

indeed it could, my only issues with that are that I don't have any. I do have a dremel. Plus my thinking was that the protrusion is round and so is the dremel.

Go for it with the Dremel. Just take it slow and easy.

Dremels can be jumpy things, but if you insist on going that route...just go easy. You can buy a decent little set of files from places like Princess Auto, personally, I'd rather file than Dremel. A little more time/elbow grease but the result would likely look better. Only time I reach for a Dremel is at times when the part won't be seen AND the area I'm workin..I can clean-up with a file.

I've also taken a part to a local machine shop, and paid for a quick job like that with a case of beer. You have options!

Take all you want off the mount with the dremel. Do you really think you will weaken the mount enough to make it dangerous just taking a little notch out of the side? I realize it's a huge recoiling .22 but still

 

[Major Sights]

Not worried at all about strength of Mount. Just the tackiness of a bubba'd part.

 

[elimsprint]

Slow and careful and you can probably hide it almost completely. Use a sanding drum instead of a carbide burr and it should come out quite clean. Or one of the small stones.

I agree with elimsprint. Use a sanding drum on your dremmel rather than a burr or stone. easier to control and will produce a nice finish .
A little spot like that, a black felt marker will touch it up.

 

[Major Sights]

Well I put on my big boy pants this afternoon, got out my dremmel, slapped on a sanding drum and went to town. I had already mounted the scope to the proper eye relief marked it, and then marked the spot that was interfering with the scope protrusion. Unmounted the scope and just lightly sanded away an area a little wider then what was needed (just in case the scope has to move forward or back a hair). Wasn't hard, just nerve wracking knowing I was using a rotary tool on a near $1500 rifle. Just looking for some paint now to cover the bare steel and then to remount the scope and hopefully sight in the beast this weekend. Oh and I installed a new Kid 2 Stage trigger while I was at it today too!

Looks good! Black felt pen has worked for me in the past, it's not going to be very visible with the scope protrusion covering it.

 

[Major Sights]

With it being steel, would the damp of being outdoors not cause the rust to form right through the felt pen job?

 

[gaff]

Spend the money and have the base machined and blued

I didn't think of that and I really don't know. I've only used it on alloy stuff as far as I can remember. I'd give it a try, I mean, how damp are you going to get the gun and how hard to clean up if it doesn't work. Another thing I have used for cover-ups is black nail polish. Put it on, let it dry and then dull it with steel wool.

Hmmmmmm.... tempting... but no... I just dropped close to $600 on the trigger. I am OUT of funds for stuff like that

Mark Lee's express brown and Oxpho blue paste from Brownells. Dont know the price but I do believe it offers protection unlike cold blue.

Or just keep it oiled and out of damp places for a long time.... Like you do with all guns.

Due to the interest of time and funds. I had the wife pick up a can of trem clad flat black. I sprayed some on a piece of cardboard and got out a tiny paintbrush and just lightly put 3 coats on and just around the affected area. The scope sits so close to the spot that it can't be seen unless you flip the gun over and grab your magnifying glass and a flashlight. She Is all mounted and ready to go now.

Just playing with the camera this afternoon.
