Had two serviced past couple years. The M8-8x abruptly turned into a rattle. The VX 3-9x33 compact EFR lost its AO. Turnaround time for each was around 4 weeks. Just got the EFR back, AO seems to work but the ocular is stiff. Undecided, have to mess with it more. M8 is fine.

Have a bunch of VX3s. First, none would pass a box test. More like a trapezoid......or maybe a parallelogram. Or a combination. Second, ergo sight-in involves multiple rounds. Cuz who knows what the adjustments actually deliver. Third, after sight-in a separate trip to verify nothing changed is necessary for some of them. No, not all of them......but which ones? None of mine are CDS. '90s to '00s mostly.

Have not had noticeable zero shift after verifying on separate trip. Which is why I continue to use them. But will buy something else going forward.
