[CAUT] WNG Action Thumping Jacks

[Andrew Anderson]

The action was refurbished by a third party, all centers were 
re-bushed and re-pinned.

The WNG action has separate springs for the rep. lever and the 
jack.  The thump occurs when the jack escapes the knuckle and slams 
into its rest.  I haven't looked at regulating that spring... maybe I 
should look at jack pinning too.
