M1941 LMG recoil spring specifications

1 post in this topic

I took some measurements of the recoil spring from my Johnson M1941 LMG.  This is what I found:

OAL, at rest:  13-5/8"

Wire dia:  .063"

Coil dia:  .808"

Active coils: 48, plus 1/2 + 1/2 closed ends

Could someone kindly confirm that this is an original spring, and whether its OAL is still within acceptable limit?  Years ago I tried to order one from Numrich, but after three tries, they still could not send me one that was remotely close or even identifiable; I finally gave up and got a refund.

Also, the bolt carrier buffer and its spring seem to be semi-permanently installed with a retaining cross-pin either welded or swaged in and polished off.  I don't wish to disturb it unless I can properly replace it.  Has anyone ever taken one out?  

Any help would be greatly appreciated.
