there is no way the glads went out assembled wrong, every single gladiator is tested on gun to check re charge time and if there are any leaks. the main problem with people is they treat it like an angel reg and wind it the wrong way, if you wind it to far the small bearing will jump the big bearing. this is like a 2 min job to fix and if anyone has this prob you can mail me or go to our tech page at www.macdev.net.
. as for the dirt issue, no reg likes excess dirt and when using a pre set you should be especially carefull not only with the fill but also screwing into the asa. get yourselfs some kind of filter for the fill and you will have many more trouble free paintball day's !!
