You ain’t gotta lie to kick it bro, I’ve never see. A module that’s not threaded deep enough to allow for lens contact.. it’s ok to say you made a mistake, I admitted I made the same one..
So you have $500 in G2 lenses? Fer why?? I build lasers and I’ve never seen a need to keep more than 10 of each on hand… and even that’s excessive lol
The G2 lenses from DTR are 100% legit, I’ve gotten G2s from a few different sources and they’ve all worked, but I’ve actually found a lens sold alone, on AliExpress, that has outperformed any other G2 lenses I’ve purchased from DTR, Barnett, eBay, AliExpress, survival lasers.. the only problem is I can’t figure out the exact type it is.. but it output nearly 7% more than the G2s I’ve gotten from DTR, a certain AliExpress seller, and Barnett, which are identical in output, size, build..
