M4 charging handle and “bolt carrier“ aka the hop up cover

Hi all, 

 

Someone please kindly educate me on how to put the parts back into the weapon as they came out after cleaning barrel. PLEASE HELP !!!! 
 

I can get it back in but the charging handle doesn’t come all the way back and the mock bolt carrier won’t come back to reveal the hop up.

The mock bolt should be attached to the upper, the part at the top of it in your picture with the small spring should be attached below the ejection port. Have a look at the receiver there may be some broken or lost fastenings. In fact you can see them if you blow the picture up, the two silver 'dots' below the ejection port. The section of receiver there actually looks bent in the picture too.

What do you suggest? A new lower or? I can’t find any lost parts. I could run it without the mock bolt but what’s the point in that haha.

Can you sign post any videos?

you might be able to re attach it with a decent epoxy type glue, I suspect it was fitted onto small pegs that have broken away. Is the upper receiver actually misshapen below the ejection port or is the photo ?

Here you go, this is how it should sit

glue is your best bet, one of the more annoying features of the m4 platform is that dust cover.....

Thanks guys I’ll let you know how I get on. I really feel like I’ll struggle with this and I’m so gutted it broke!! Haha. The pictures are a massive help Nick thank you but is there any chance you could send some more with a bit more detail ? I’m really really no tech (as you’ve probably already worked out) what bits need gluing to where? Haha and yes upon closer inspection the receiver is bent! 

Dunno why my last post said Nick said it.. he didn’t..

the bolt guide probably came off when the receiver got bent . Only pics I've got I'm afraid but if you look at them carefully with your parts in front of you, you should be able to see how they go. You'll need to sort that bend out first, or just shop around for a new upper receiver that you can swap the front end over on to.

I never bother with the fake bolt. I take it out and reverse the spring in the dust cover. That way it stays shut then I can get a nail in and open it if I need to get to the hop

Woo we got there! Un-bent the upper and epoxy’d the tab! All I need now is a new charging handle spring (may even cut it down) but again thanks guys.
