I have experience working with an Aftermath M4 and an ICS M4. My friend recently purchased a King Arms M4. I was looking on the internet and came across this video for separating the upper/lower reciever for a King Arms M4A1
Weapon Breakdown - King Arms M4A1 - YouTube
It mentioned that because the King Arms M4 has a catch for the charging handle (keeps it back a bit so that you can adjust the hop-up), you don't separate like a normal M4. Instead, he shows you howto slide the upper reciever forward to remove it from the lower reciever.
Can anybody confirm this is true for a 2012 King Arms M4 (the $265 gun from ##########)?
Also, I have been searching, but couldn't find any video/instructions for taking apart the King Arms M4. Is it generic like any other M4 or it special like shown in the linked youtube video?
Does anybody have a link to instructions to take apart the King Arms M4?
