Got this G&G ARP 556 like that out-of-the-box.
I noticed that the charging handle would not pull all the way back or pop-open the dust cover. Didn't want to force the charging handle so I decided to remove the upper receiver to inspect further and the first thing I see is this - Is this piece supposed to look like that, or did I get myself a lemon?
When the dust cover is off, the charging handle can pull the bolt back, let me adjust the hop-up, and return to its original position just fine. The jamming with the charging handle happens again the moment I close the dust cover and I won't be able to open it again without first re-disassembling the upper each time.
How easy is it to replace this piece? Is the ARP 556 built close enough to other M4s that I can just swap it out with another one or is this proprietary?
Any advice would be great, thanks in advance!
