Mine so far, just got it yesterday and stripped it down AMD cleaned it all up. I will do this again tonight even if I don't shoot it today, I just feel that it should be done a few times to really get to know it's inner workings... But a red dot tube and a 3x magnifier will go on next month, the month after a red laser on top, and the next month a taclight. Other than that, I'm not sure, I think if will pretty much be done, oh yeah, and a popup BUIS.
IT WON'T LET ME ADD AN IMAGE, SO I'LL HOST IT SOMEWHERE ELSE LATER, AND GET IT UP.
