Hey Guys,
Do any of you recognize this receiver?
I'm assuming it's some sort of small ring, and was hoping that an old Browning barrel I have laying around (243Win) would be suitable for spinning on.

Thanks!!!

Going by the pics. it looks like the front ring is thicker on the top & bottom, I suspect it's a large ring turned into a small ring with large threads 98 Mauser. I would like to see pics. of the bottom metal & bolt - how many locking lugs 2 / 3. A .243 is fairly high pressure and as such taking into account the action may be modified as I suggest - I would not, but others more knowledgeable may chime in. JMHO - FWIW. --- John303.

I know my opinion doesn't count for much but I think John303 hit it right on the head. Charger hump and front receiver ring ground.

Steve E.........

small ring front lug shape?

Looks like either a scrubbed small ring, large thread Mauser or a large ring ground to small ring contour. Probably the former.

I have a small ring with large thread Polish (Same as Kar 98) and the recoil lug is the same. Both the Kar and the Polish version have integral hand guard flanges on the top of the front ring. All the custom guns that I have seen have this flange ground off. The above action seems to have had a lot of metal removed. From what I have learned here on AR, these actions are not very strong to start with, let alone with extra metal ground off. Having said that, I must admit that I once saw a very nice custom 270Win built with an Erfurt 1917 Kar action. It was put together by Gene Simillion. It had been surface ground and re-heat treated etc. I think I would feel better using the above barrelled action as a garden stake. I'm thinking the same about my small ring Polish 98 as well. I was advised to only use these actions for very low pressure and low bolt thrust cartridges, as there were even some problems with the original 8x57 chambering.

When I measure across from 3 to 9 O'Clock, it reads about 1.278. From 12 to 6, it measures about 1.305.

I think that front edge is just damaged slightly. I think the angle of the photo makes it look a bit off, but in person, it looks pretty uniform all the way around.

Does anyone know how to decipher the marks on the bottom side?

Tend to CM ´s opinion.
The polish like the German carbine version had a metal sheet , which was part of the front ring, to hold the upper stock part in place.

If you civilize the action you must file that part down.
Improperly done you have the picture we can see here.

Stokes,

So - Those early Browning FN Highpower M98s in .243 & .308 (before they went to the Sako actions for those cartridges) really are small ring actions? I thought that they might be large ring shank that were ground to small ring contour, externally. I have never found anybody who had pulled a barrel to know for sure. Except you, it sounds like.

I have one in .308. Interesting, and good to know.

You know.... I was just assuming that, but I haven't actually checked it. So, don't quote it as gospel yet.

Tomorrow I'll dig it out and measure it.

Browning did make a standard action lenght SR, small thread in the FN Supreme 400. A few around but not many. --- John303
