never cleaned it!?!?! how long have you had it?? how many rounds would you say are through it!? thats just amazing to me lol...i never had real troubles with mine, but notice when its definently needs a cleaning when it starts to have troubles feeding...either gums up from shooting cheap ammo, or the feed ramp gets leaded up, when shooting cheap ammo...still usually clean it every time i shoot it....just a habit i got from dad i guess....
