Sounds like you've taken a good step forward. If your serious about doing your own maintenance, upgrades, etc; find an experienced gun doc to show you the finer points of quality, shimming, etc. Do yourself a favor, and buy "quality" gear. "Buy cheap, buy twice"; is a good ol' ASC moto. Sometimes it's buy three, four times.
Sorry to hear your first "serious" game didn't go smooth. It is a sport where mistakes do get made, by everyone. And you numb yourself to BB hits over time. Except knuckles, ears, nose, etc.
I’ve developed a new sport I call ‘Airhard’. It’s basically Airsoft, except while you play you must maintain a massive erection...
