I hae had an RO out here in CA be a total moron too.
i had just finished breaking in my new m1a and the guys had been watching over my shoulder the whole time(i think he didnt like seeing a 18 year old with a NM m1a:p ) and it happened to jam(due to a headspacing issue on some reloads i wanted to polish off) and he went nuts, he basicly panics, forces the range to shut down and proceeds to tell me that it can be unjammed(bolt was stuck REALY well) so meanwhile while hes running around like chicken little, i set the rifle on the table, cocking arm down against the edge(barrel down range of course, range clear) have my friend hold it, and i kick the butt, out pops the round and the ROs jaw drops and he kicks me off the range for clearing a jam(he gave me a bullshit line about how they had to have their on-site gunsmith look at it... HAH!) :/ about 2 months later the range was shut down.
it just recently reopened (after 4 years) and the same jackass is still there, now they dont allow even the CA legal ARs:/ sigh, im so glad im getting out of this state next month.
