so i bought these mesh goggles and they just came in today. they seem alright but then i noticed that htere was a gap near the frame. see pic. what are your thoughts on this? is this a big issues worth returning the goggles for? how dangerous would it be to use it? please give me your thoughts... thanks

so i have the g&g gkms which has the pneumatic blowback, i was wondering if preventing the charging handle from moving back would damage my gun or the blowback system. thanks

Fuck me, do I have to take it apart or can it just dry up or maybe by firing some rounds through it?

So i sprayed some oil into the hop up slide and the feeding tube... Also cleaned the barrel but that wasn't dumb Basicly now my hop up is not working...like at all. no spin on the BB's at all. DId i fuck something up really bad? or once the oil comes off it will start to work again? P.S I sprayed a decent amount Please don't hate I was drunk and clueless
