A while ago I gotten my dear Brno m-21 action. The action was cheap since it lacked bolt and some missguided fool who should been sent to prison had drilled and tapped the action for weaver bases.
Thankfully the squarebridges are still untouched and have not been touched or reshaped
I have consulted a few gunsmiths and gotten different suggestions how to fix this problem.
1. Weld up the holes with a TIG. What risks is it with this operation? What work is needed to be done after this?
2. plug the holes with a plug/rives that will be a bit oversized so it will fill up the hole and lock it self in the thread.
What to do? According to the Mauser collectors, action is made of poldy steel and not the same soft low carbon steel as obendorf mausers.
I assume from your description it is drilled on the side...I would first try to find a side mount or have Griffen and Howe install a side mount....Might even surface grind it to a round top receiver....
To repair the holes, I would drill out the threads with a taper, use a hot pin and tig them in, broach the inside if I could, surface grind the outside surface and hone the action inside and out...Jack Belk does this real well...I usually have him do the tig work and I polish it.

the risk to weld the holes it's you can see the spot after bluing as the steel of the BRNO actions are a bit different , I'll try to plug the holes , I'll made two threaded plug with soft steel , screw it cut and taper with a little hammer until it get flush with surface , filed and polished you can't see it , also you can screw and soft soldered the screw/posts ,an option to hide the screws , you can ask to made a engraved surface , if you dislike the finished product later you can weld it .
Hej Johan why don,t you put a screw inside the hole and then solder it at very low temprature or using locktite.All kind of welding produce a great amount of temprature which can cause softning in the action's steel or creat tension in the steel which needs stress releiving or can cause cracking(especialy in high carbon or cr mo alloys)!. why can't you leave alone those holes? rgards danny

Johan, whatever you do, ignore the comment about installing side mounts. You have the best scope bases integral on this action. I would go with the soft plugs. Have your smith use a countersink and create a small bevel at the top of the holes. Peen the plugs and then dress them flush. If yours is like mine the top has those squigly lines that you will unlikely be able to recreate but it will be less noticeable. Good Luck.

Thanks for the advice, That is the way that I have been planning to go.
Side mounts my butt, I wonder what Ray Atkinson had for brunch, burbon with rocks or a plate of beer with some tequila Ray have you been drinking again, if not I suspect that you rifles are living a dangerous life in you vault beening threatend to get sidemounted
Ray is probably thinking of the pre-49 rifles that do not have the dovetails.
I would say that yours is salvageable using any of the above plug methods, and your rings will hide it. It is when the holes are in the early model round top receivers that it gets frustrating. Trying to duplicate the logo in the front receiver ring is difficult, if not impossible.
the logo is still intact and they have to my mind done some thinking before they drilled the receiver. I just called my engarving chum who said it would be "NO problem to fix the pattern"
Now, the hard question is what to make of this action, caliber etc. this is a difficult, but pleasant time for a mauser loony
Roger, I have a squiggle job for you sometime. I have a 7X57 Krieghoff bolt rifle with a half round half octagon barrel and a plug has been installed in the integral rib and it should have some squiggles. Either that or reinstall a rear sight. BTW, trust you to be able to do that (squiggles) and carry it off. If I even tried it, the results would look like a road map of I-5, complete with consruction detours. Probably why I do not do that stuff.

in our company all vitamines are free from charges for all the members, you take too much C-vitamin and you get high if you take too much B-vitamins then you need to sitt down for a g��d while on toillett chair because it becomes laxative). i get the cds it was a lot of fun . i beleive they took a lot of long shots and the old fat guy with german accent shot very lousy with his blaser and what was the calibers used by that little guy with a big nose and stainless fluted red barrel he made some good long shots. regards danny

Here is what I've learned about repairing holes in actions. Drill out the hole and taper ream it. Use a good TIG welder with HF start only and a tartan TIG Rod. Totally clean the action and metal before starting and use as low an amperage as possible. Use a swirling pattern to how the tig electrode is held and make sure there are no PITS. Work swiftlyand pay attention to the heat generated or your action will warp! It's generally no problem on the action rings, but filling side mount holes requires another level of expertise. You then have to mill out the residue from the action rails. I wrecked a good action learning how to do this so beware. Not trivial. Consider simple screw plugs as a better alternative unless you can find someone who damn well has done this before and can prove it to you.-Rob

I had a bolt in my favorite drawer that were already polished and ready
The action doesn't have a caliber right now, but it was a 7X57 when I found it, actually it was a real horror rifle, cracked stock, rusted out barrel. One thing is clear, the previous owner wasn't a great mauser loony that took care of his guns
I guess that you have some sort of trouble I guess that you got an action luying around, or that could be bought for a great price If soo I might be able to help you
Johan why don't you cut it in two at the thumb cut & weld another receiver rear onto it & then you have a nice Kurz action!

Johan I was looking at Clarks post & thinking of the thumb cut & typing my post. Must have been a senior mement. I just couldn't bare to part with any of my Mausers...I would surely need therepy afterwards with the withdrawl thing & all.

Johan, does it take the standard K98 bolt or is it shorter? Is the bolt shroud different on the bottom to allow it to pass over the tang? The barreled receiver actually belongs to a friend of mine and it is minus a bolt assembly. He tells me that a K98 bolt won't fit this action. It is a very neat lightweight rifle set up strictly for open sights (very low comb) and is a 6.5 caliber. Not a 6.5 X 55 swede or 6.5 X 55 MS. It's a shorter caliber than these. Do you have any more bolts that would fit it or know where I can get one? Thanks.

would you please post a few picture of the gun? Option is to send them to me by mail? THis sounds really interesting. When is the rifle made? look at the left side of the action near the barrel, there are some markings.
Humbarger, I forgive you for your sloppyness, this time Next time the mauser mob will strike
Imagine how horrible life would be without mausers

Regarding Blaster`s guns, I alway think of a green plastic gun I won at the marketplace tombola when I was six years old.
The Brno is a real gun for real riflemen. The Blaster isn�t. Period!
Here is my own favourite BRNO, a ZKW 465 in .22 Hornet:
It is made 1948, and the work and finish is remarkably better than that of my two years younger Mannlicher-Schoenauer.

The bolt from my 1946 22f is interchangeable with the bolt from my Brno 98 (EAA import). The only difference is that the 22f lacks the guide rib on top of the bolt, even though the receiver is cut for one.

A real rifleman doesn't need pretty little rifles that work smoothly to inflict maximum damage.

If you rifle is a Brno m-21or 22, a normal standard bolt will work just fine. I tried a mauser obendorf bolt with the Brno 21 receiver made in 1950 it worked just fine with all the guide rails etc. Make sure that you action have the slots for the bolt rail.
Fritz kraut, Very nice rifle, Thoose small Brno's are a real treats Do you need a new toy? Give me a call, I might be able to help you , PM sent !
I must thank you all for you effort to help me solve this matter, but today I got an offer that I couldn't resist, the action is GONE. The new owner will make a nice 7X57 on is, which will suit the action very well
