Let me show my ignorance: What is a tuning fork test?

The stripped upper receiver forms a "tuning fork" that when gently tapped on a non-marring surface, will ring. Repaired, re welded, cracked or messed with upper receivers are not supposed to "ring".

This is more lore than science, but some people do it.

I when I learned of this test on Lugers, I had to chuckle. It reminded me of a similar and valid test performed on forged crankshafts for performance engines. If they don't ring when tapped, look for a hidden hairline crack.

Hi Mark,
Congratulations, it looks like you have a very nice DWM Artillery, 1915's are hard to come by. As to shooting it, read this and then decide.
