Eversull uses a very expensive laser welder. No spray welding in his shop. Alot of high end gunmakers, here and overseas have bought into the laser welding method. I had a Brit gun put back on the face last year using this method, even under a jewelers loup you cannot tell there was any work done at all. There is a gentleman in Michigan that laser welds for the trade. Next to Eversull, he's the best in the business. Extremely precise work.
