I don't know of many sites now that allow auto up close? So the flip magnifier loses its' usefulness. The Elcan product line is notorious for being rock hard irl, hence it's seen a lot of machine gun usage with various forces over the years.
I'm not really up on the latest clone optics, but holy warrior seems to be the way to go. Got a few Aimpoint T-X knock-offs here and an EoTech magnifier and they're lightyears ahead of the generic chinese optics I've got from the early days of such products being available. Though I also have an HWO EXPS3 that doesn't turn on and seemingly the battery compartment is just straight up built/sized wrong for any battery type I've ever seen, so the usual risks with aliexpress type dealings are ever-present.
