terminator9272 Posted March 26, 2018 Share Posted March 26, 2018 Hello, Trying to disassemble my GC16 Predator, I have the stock and hand guard off but I cant get the upper receiver to slide off. Both pins are punched out as seen in the pictures however it is not moving whatsoever. Anyone know why? Link to comment Share on other sites More sharing options...
Supporters Sitting Duck Posted March 26, 2018 Supporters Share Posted March 26, 2018 usually..... pop pin closest to hop receiver slides forward inch/25.4mm then sticks..... pull charging handle at back slide receiver a bit more forward and lift slightly up at back continue to slide off receiver you will see a little lug on top of gearbox of most M4 gearboxes I reckon that was impeding the receiver sliding off (some v2 gearboxes like MP5's don't have this lug) should not be a blowback model next time please trim photo to not show your crotch if possible Link to comment Share on other sites More sharing options...

Supporters Prisce Posted March 26, 2018 Supporters Share Posted March 26, 2018 Could be wrong but doesn’t the safety lever have to be halfway between safe and semi to remove this upper receiver? Link to comment Share on other sites More sharing options...

Soz thought it was a generous 2-tone paint job It is just stuck me thinks... Link to comment Share on other sites More sharing options...

SOFTLY - SO IT DON'T MARK DAMAGE STUFF it has gotta go I would have thought - or did tech glue the bastid ??? Link to comment Share on other sites More sharing options...
