I'm sure Cooey made the peepsights. They are adjustable, but rather basic. The M82s shoot quite well, but keep in mind that they are a Cooey "Senior" in a paramilitary stock.
Has anyone seen one of the other Cooey trainers that has a butt which is contoured like a SMLE? Not a M82. I've seen photos of one, and my son has seen an actual specimen.
