Oh, and PS, welding or grinding on M1lugs is not an accepted practise ANYWHERE. It is possible to build up a Garand lug with the right TIG process and rod, but it would involve pre-heating the bolt, using the right rod alloy, re-machining the lugs to the right angle in a precision fixture, annealing the bolt to stress relieve the weld and the work hardening from machining operations, then re-heat treating the bolt to USGI spec. The whole affair would then have to be tested for porosity or other indications such as stress cracking using either LPI dye penetrant testing, magnetic particle inspection, or magnaflux/x-ray testing as well as hardness tested to confirm everything went well and the bolt would then be re-parkerized.
Nobody does this in practise because the bolts are still readily available and are often interchangeable if everything else is within specification.
The Tippo 2 guns being sold by in Canadaright now did NOT follow the above noted process to weld the bolts, I can iron-clad guarantee that. Heck, the photos being posted around would be called visual failures.
