i had this on the millitary surplus forum and was told to try it herer instaed. so...

hello all. i have a spanish mauser that i'm going to have drilled and tapped by a friend (amacher gunsmith) he's a good friend and a very good marksman he said he has drilled a few 98 mauser in his day and that all he would need is the scope base. well here is my problem i was looking on midway and saw that they had mounts for many different mausers (ie some for 98's some for 93's........)i want a two pice mount and i don't think (from what i read on midway that i cann't use 98's on my 1916 mauser , which is a 93) so what do i do?? if it is a two pice mount then i think it wouldn't matter because i believe action length is the only thing different. some one please educate me please. thank you

There are receiver ring size differences(shapes). For the Small ring M93 such as what you indicate you have(M93) you will need Weavers 2 piece base number 55 for the rear base and a number 46 for the front. There is also available an extension front base if you need it, number 402. It would be used in place of the number 46 if you thought you might encounter eye relief problems with the scope you have chosen. It reverses allowing a bit more latitude in the forward and backward placement of the scope ring and thus the scope. The Brownells catalog No.56 was used as reference for this although 57 is out. It's in the shop and I'm too lazy to run and get it.

Those are the correct numbers but the links were to bases that were finished differently. Weaver bases can be had in matte finish, polished finish, and stainless steel finish.. They are also available in steel now under a seperate subhead. Use bases and rings that match the finish on your rifle... bit the numbers were correct.

gunnut69 i have a problem i ordered the weaver bases number 46 and 55. the number 46 works fine but the 55 is too big by about 14.5 calibers and hits the bolt open opening. lets see if i can describe this right.on the back part of the receiver there is a lip (where you put the striper clip in) that goes up and stops you from mounting the base any farther forward so the base (number 55) sticks out and hits the bolt. and there is just barely enough room for both screw holes. so what do i do ?

I assumed since your friend had done M98's he was familiar with the process.. The hump of the rear ring helps the stripper clip stay upright while being loaded into the weapon. It will either have to be ground off or the base ground to clear. The mount may still over hang the rear of the ring. The area it overhangs is the extraction cam for the bolt. It applies camming force to the bolt to break a fired case from the chamber. Simply mark the base after fitting with a scribe and remove the base. Grind the excess material away and polish. A bit of baking lacquer or paint will cover the bright aluminum. Be careful if you chose to remove the clip loading hump to avoid major reconturing of the rear ring. If it's changed too much the base will no longer fit or it may be too low to align with the front base. This is a common practice with mauser actions of all types.

that kinda what i was thinking but if you were to ground the base down you would have to ground it a little into the second screw hole. that would mean only one screw would be holding the back mount on and i would think that it would move under recoil?

am i somewhere in left field here???

Some small ring mausers will not allow the base to be ground though most will. The base is ground at an angle to conform with the rear edge of the clip hump. The bottom of the grind mark must stop at the edge of the forward screw hole on the underside of the base. The base will still hang over the rear edge of the ring a bit that is ground off. This provides clearance for the bolt handle when it is being opened.

boy you would think they would make one already set just to put on in stead they have you do i'll this crazy stuff . is there a base out there that is already grounded off at the right angle? (just wondering in case i ever do this again i would like to be able to do it myself but all that gounding is a bit much if you ask me)

Most of these are installed by gunsmiths and they usually remove the hump from the stripper clip slot. It makes for a nicer, cleaner look. This is not a difficult operation... and is widely done. Some smiths use a surface grinder, others a special jig, and some just eyeball. Good luck with the 93. By the way a little notice. I once found a 93 with a cracked bolt face and am a real worrier. The crack was circumferencial and followed the joint between the face of the bolt and the surrounding edge. It's one of the few faults I've found in many years of looking..

My '93 Spanish Mausers are .081" higher in front than the rear.
If a Farrell one piece mount were used, it is .157" difference, which means .076" of shim in the front would be needed.

For hunting rifles, I prefer two piece.
I allign them with a scope and rings while I glass bed the fit of mount to reciever. When the glass sets up, I tighten the screws.
That way I don't have to lapp the rings.
