I was looking over youtube today to find this video of the PTR-91 rifle being played with in the mud have a look.:biggrin:
No gun is going to work well if at all after you put mud in the chamberDon't know what reliability ya'll are talking about but I call it just shy of a miserable failure. Just shy only because he restored it's function with water, albeit muddy water. Fun to watch but I'm not impressed. Camera guy sucks too, all shakey and screwing around.
