View Full Version : anyone here put a scope on their k31?

04-17-2010, 2:03 PM
Recently got a k31 and am looking to put those no-gunsmith mounts (http://www.surplusrifle.com/reviews2006/stmariescopebaseswiss/index.asp) and a scope. The question I have for you guys is which "St Marie scopes base" should i use the aluminum or the steel? What rings should I use? And what scope should i use? I always hear that half of the cost of a precision rifle should be on the glass, I got mine for $180.

Heck, what you guys have on your scoped k31's?

I recently picked up a 2nd K31 with the idea of doing the same thing. I just haven't got around to it yet.

The owner of st. marie prefers the aluminum. I think he said he produced the steel version because there was a demand for a steel version rather than a need for improvement. I'll look for the post.

found a post re:aluminum vs. steel. the guy posting as "swiss products" is the son of the St. Marie owner

I'm very happy with the aluminum on my k31 with an old timey weaver K4. I'm using medium Warne 7.3 Rings

I just picked up a K31, I was thinking of doing the same thing. The finish on mine is very poor but the barrel is nice so I may use it for hunting. I know refinishing isn't the way to go on a collectible, but the wood on this thing would look so nice......I don't want to drill the receiver either like you. Finding the right glass with enough relief so it's pleasant to shoot would be key.

The only time I use a butt pad is to keep from getting scope eye while shooting my K31........with the aluminum St. Marie.

I have the aluminum Swiss Products mount with Warne 7.3 rings. Very happy with the combo.

I used the aluminum mount, and I can't remember what rings. The current scope I have on there is a Mueller APV. The only issue I have is that the scope is in the way of the brass ejecting - they hit the scope and fall back on top of the magazine. I find that if I tip the rifle slightly to the left when working the bolt, I don't have this problem.

I used the aluminum St. Marie clamp on mount and added a repro #4 cheekrest to get a better cheekweld for the scope. Since this picture was taken I've installed a Nikon 3-9x scope in place of the Buschnell 4x. The clamp on mount works great for me but I am left-handed, left-eye. Seems to me it would be awkward for a right handed user.

BTW remember to remove the muzzle cover before shooting. I shot one off mine. I found the spring clip that holds it over the front sight. The rest vaporized.

Cool info.....please more details on scopes and rings.....and if you have any brass issues with your setup. I don't really want to have to tilt the rifle to the left every time I cycle the bolt....I might remember at the range but in the midst of hunting excitement I might forget. Anybody try and add a little brass deflector?

04-17-2010, 6:39 PM
Some people add brass deflectors. If your scope has a side parallax adjustment knob it's more prone to making the brass fall back into the receiver.

Otherwise, a quick hard pull on the bolt handle when ejecting usually suffices to throw the brass clear.

Check out swissrifles.com... You will find a boat load of info there.
Did you check under the butt plate for a troop tag?
I search and I think I found the original owner in Switzerland, I might write him and let him know where his rifle is.
I too have the aluminum mount with Warne 7.3 rings and have a Nikon Bushmaster 4.5x14 x40 with BDC reticle.

Yup St. Marie Aluminum mount. rings? whatever I had laying around. Scope An old Simmons 3-9x. Setup works.
Lightly refinished w/ Bullseye Amber Shellac.

Well it looks like i got some nice data on what you guys use along with some nice pictures. Smle-man, because of you I now want another k31, I was almost done with my C&R habit. Just needed to grab a m1 carbine and I'd be finished.

Pthfndr it was originally your old post on 1000 yard shooting that made me want to scope my k31 (http://www.calguns.net/calgunforum/showthread.php?t=148708). Do you remember what the new shooter you were helping eventually used for a scope, or did you point him to the Leupold MR/T 2.5x-8x with the Tactical Milling Reticle that you used in the test?

I use a Steel St. Maries... it's rock solid and I'm happy with it.

Scope Leupold VX-I 4-12 variable

Gets hauled back and forth to range and never seems to loose its' "zero"

Haven't had any issues with brass hitting the scope.

Get a scope.. you will be glad you did.

Heres mine.

. . . what wood is that? And what finish? I like that, I think I can do that with mine.

This thread is really making me want to put a scope on my K-31. I'm a total noob to optics, looks like this might be a cool way to get started figuring all that stuff out. Nice rifles guys!

04-22-2010, 2:24 PM
Thanks. Honestly, i dont know what kinda of wood. I had some stain laying around and used that with some polyeurothane finish.

Unless it has been heavily damaged, leave it alone. K31s are either Walnut or Beech.

What if it's somewhat damaged? I'm just saying it looks nice.

I originally was going to end my C&R collection/habit with an m1 carbine, but now I think I'll grab 2 more k31's. One walnut and one beech so that I have two beech rifles. I'll test fire both, keep the most accurate and sell/trade the other for other k31's in hopes that it's even more accurate.
