I would be concerned about reliability after the above operations. The 'lug' exists to start the bolt rotating into battery. Without it, you get 50% (or worse) bolt-fully-locked-in-trunnion reliability.DoctorCheney223 said:- removed the "lug" from the left side of the trunion (inside and out)
- TIG welded the holes where the old trigger pins and trunion "lug" were located
When you tig'd it back up, did you recreate the existing depth and diameter of the original 'lug' or tig up a 'shoulder'?
I believe the Russians have gone to the use of this 'lug' to lower their costs of making barrel trunnions. They can use a different sized 'lug' in the same barrel trunnion depending on the caliber of rifle they are making.
