First zero'ed it at 100 meter, this was the first set of , 11 shots after zero'ing it.
Didn't have a bipod or bench rest , just rested it a wooden plank
Then my front aperture fell off and i didn't have the right allen key with me to tighten it up again.
At first it wouldn't cycle, turns out the gas valve was set wrong..
Then it cycled.. but had a couple of stove pipes.. I'll take it apart, and clean the gas system properly... It seemed to improve as i was finishing up..
I think it's safe to say , the Zombies will have to keep their distance...
