I deal there regularly, and have done some very good and profitable business. I just don't even open any other forums. It's like children screaming in the darkness...

Oh, and PS, welding or grinding on M1 lugs 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 Canada right 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.

Thanks for clarifying who founded this site. I appreciate the international membership because of the vast knowledge base.
As for the T2's, I have sent mine back looking for a refund of all monies paid. The company said it will not pay for my shipping charges unless they can prove it is unsafe. All they have to do is turn the barrel by hand and it will come undone. As far as I know, a lose barrel on a rifle is not safe. Also. because the rifles were "proofed", they are claiming the rifles with the welded and/or grounded bolts are safe to fire. I just hope nobody gets hurt firing one of these rifles.

I would agree - a barrel that is not tight to the action is a defect that should be covered by warranty. It might not be "unsafe" depending how loose it is, but it will not hold zero and will not give consistent headspace measurement.

The correct fix would be to roll peen the barrel shoulder and re-tighten the barrel. If this does not fix the issue, then on a barrel that needs to index precisely like a grand and where length cannot be easily altered, a new barrel would need to be installed.
