Can my 93 Spanish bolt be changed to cock on open rather than closing.

Brownells; Dayton Traister cock on opening kit. You have to mill the cam.
However; cock on closing is not broken; I do not understand the need to change it, and I have done them.

Yeah, never liked the conversion kits. Prefer to leave them as is. You want COO, get a 98.

Well it was just a thought altho I need a safety for it as I am putting a scope on and the flag will be blocked. Thought that might have been the easy way to solve the problem.

The Buehler style safety now made by Timney is probably your simplest solution for a low scope safety.

There is a fellow on another forum that is converting M93-96 bolts to M98. He cuts off the handle end of the M93 style bolt and welds on the corresponding end of a M98 bolt. He is using FN bolt bodies that SARCO is selling for $5 each. Gets a FN turned down handle in the bargain plus a little safety upgrade. The rear receiver bolt raceway has to be opened up to accept the larger diameter 98.

That is way too much work to put into a 93.
If you just want a safety, get the Buhler low scope safety.

I’ve seen 93 bolt shrouds that have a safety flange like a 98 welded onto them to divert any escaping gas.

Ed LaPour does about the finest CCO job as can be had..With a 3 pos saety, it will set you back some $$$...But If it's not worth doing it right, might as well not do it at all

93s are fine for tinkering but not worth putting any real money into.

I disagree. Pleasure is sometimes having something different and causing that to happen without regard to investment return. $75000 pickups are worth half that in a very short time and shortly thereafter are worthless...Yet, the buyer considers the money well spent. Same with an $800.00 custom knife, when perhaps a $40.00 one will "do"...well...you get the idea.

Without such a mind set, you and I would be begging for a job flipping hamburgers.

Check with Jim Wisner as well and see if he has anything that can get you there.

JW does make his M70 type for the 93/4/5/6s. Or used to anyway. I have a fixture for them somewhere.....crap, lost another fixture.

Agreed, if I HAD to have a COO conversion, it would be Ed's!

Jeeeeze I had forgotten all about the Buhler safety that will solve the problem nicely. It ain't easy getting old

ALMOST a Mexican Mauser..but not as good

I wonder if an intermediate action M98 bolt could be fitted to a Swede receiver. Then counterbore the breech to mimic the M98 breeching?

If you did your only gain is a safety lug. You wouldn't have the inner C ring in a 93/4/5/6 receiver. You still have the early receiver and the bolt is not the weak link anyway.

D that's what I am saying. If you counterbored the breech end of the barrel to form a "c" ring would it or not serve the same purpose(and be as effective)?

I say no; while it would make it like an Arasaka, it would not improve the strength of the receiver. When the gas comes out in a bad situation I think the receiver will go anyway.

A few M 1889 Belgian Mausers were updated to use the M98 bolt sleeve by milling the rear of the receiver to clear the larger diameter. I have one of the receivers but no bolt. The sear that was included is cut back about .200. To use the M98 sleeve anew firing pin may be needed. I have not studied the firing pins yet.
The M89 is very similar to the M91 except the extraction cam on the receiver is about 1mm further to the rear. A M91 bolt hits the cam before the bolt turns down.

To provide a little info
The M98 shares the same buttress threads on the bolt sleeve as the M93 and M95. The position of the thread seems to be the same when screwed into full depth. The M96 threads are close to the same as the M95 Nd M91 bolts that I have but the M96 bolt sleeve threads are located about .020 further back toward the sleeve flange. As a result the M96 sleeve hits the bolt handles of the M95 and M91.

I learned this looking to update M91 Mausers to replace the older firing pins. Using a later bolt sleeve and cocking piece will permit the use of a more common safety. The front end of an M93 or M95 firing pin has to be shortened.

What I am getting at is it should be easy to mill a M93 tang to clear a M98 sleeve if you want to try those.
