I'm attempting to buy a receiver sight for Mauser 98k. Are bridges of "large" and "small" ring Mauser receivers the same. Only receiver rings and, perhaps, receiver overall lengths change. Receiver sight bases for 98k and FN small ring Mausers use same receiver sight bases? It's so simple to be wise. Just think of something stupid to say and then don't say it. Sam Levinson | ||

I just went through each post of your detailed thread. Unfortunately there is no information pertaining to Mauser and Mauser-style turn bolt actions' receiver bridges. I believe I found the information I needed by way of what is the meaning/translation of Redfield and Lyman receiver sight model naming. If this method solves my problem, I still will not know anything about dimensions of receiver bridges. But knowledge about receiver bridges was wanted only to identify what receiver sight would fit my receiver's bridge. It's so simple to be wise.

You might want to post this in the GUNSMITHING section. I'm sure DPCD can answer your question as well as others. I believe when they say small and/or large ring Mausers they are referring to the front receiver ring and in which case you are only concerned with the curve of the rear receiver ring as the receiver sight is height adjustable.

All you had to do is ask me; not that I know anything about Mausers, but I have 200 of them, left. Ok, the bridges on all 98 pattern military Mausers are the same, and as Hip said, only the rings (front) are different. Now, an FN small ring? I have to see that one. When the term 98k is used, that means the German Kar98k rifle made from 1934 to 1945. No other rifle is called a Kar98k. So, to make sure, give use the markings on your Mauser. Yes, a gunsmithing topic for sure. | |||

I realize that this topic is about military M98s, but just as a point of interest, Browning did use a small ring, short FN action for their early High Power rifles in .243 and .308, before they switched to the Sako action for those cartridges. At least they were small ring externally. I am not sure if they are actually threaded for a small shank barrel, though. And they were apparently shortened by cutting the front of receiver ring back a couple of threads. I suspect that they may have started with the standard large ring FN action and simply modified the ring as described. I have one, but I’ve not pulled the barrel to verify that. | |||

I was looking at one of these many years ago at the Riviera show in vegas. Should have bought it. I think I see some folk refer to it as a pencil barrel.

All of the standard calibers had 'pencil barrels'. Had nothing to do with the receiver used only the terminal barrel diameter and taper used. | |||

I have found the rear bridge of the intermmediate Mausers, like the M48 and 24/47 Yugos have a different radius than stnd 98's. Rear sight bases may or may not fit properly. | |||

The rear ring has the hump that needs to have the cut out or modified scope base, the hump or scope base can be milled (surface ground) on those Mausers to mount a scope. Ray Atkinson Atkinson Hunting Adventures 10 Ward Lane, Filer, Idaho, 83328 208-731-4120 rayatkinsonhunting@gmail.com | |||

I like to leave the clip-boss hump, Ray, and have found mount bases that go behind it. It adds decorative interest, like the bolt shroud and the Enfield's dog-leg bolt handle. Our eyes like curlicues, probably why fewer people get upset when old 'modernist' architecture is knocked down. It seems this need of visual stimulation even applies to critters. Apparently some country along the Platte River was so flat and featureless that mules used to go to sleep while pulling wagons. | |||

And I Always cut them off! So I can use the longer FN rear base, or a one piece Leupold base. It does not belong on a a scoped sporter; only on one without a scope. | |||

My comments refer to the contour behind the charger hump, not the hump. The radius is flatter and the center of the base may not contact the bridge. | |||

not the best. LR on the left (VZ24), SR on the right (swed) :-)  | |||

You can usually find them at woodworkers supply houses, called a contour gauge. | |||

I think of it a bit the way you do about common cartridges, dpcd. That picture of the action with the clip boss milled off looks a bit boring to me. I'm also a fan of the bolt-stop housing - much better to look at than that skimpy thing FN put on their later commercial actions. I have used a one-piece Leupold (STD) base over the boss and the only downside I can see is that it only provides for one screw on the bridge. If strength is important, though, perhaps we could think about the loss of rigidity that removing that higher arch of steel might bring. Obviously you think this is no biggy, but the channel for the bolt rib means the metal is pretty thin along the top. | |||

Frank de Haas in his "Bolt Action Rifles" states that the large ring M-98 is to be preferred for reasons of strength. Just a few ounces difference in weight. I am preparing to have a gas port hole added on the left side of the ring to my custom 98 rifle, as it can be done opposite the underside bolt two ports. The Mauser 98 bolt shroud flange protects the shooter along with the bolt ports. But as de Haas points out, a left side ring port hole provides a bit more outside gas exit to a pierced primer. The 93 Mausers had this type of ring porting, as does the pre-64 M-70 and o3-A3 Springfields. Avatar | |||

Two comments; that base above; YUCK. The comparison has to be of large and small ring 98s only. 93s can't be part of the comparison; they are definitely weaker. | |||

(barf) looks like you could take a block of aluminum (or belt down cans) and make that "functional" base, with a deathwheel (angle grinder cutoff wheel) and a hand drill -- opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?
