Ok, I was doing some general maintenance on my AK-47 and cleaning it when I removed the Muzzle Accessory. I pressed the pin down to hold it and noticed that the pin stayed down (5th picture, Green arrow) and didn't come back up. I was wandering if anyone had a reason why this is doing that and how to get the pin to come back up without messing up the finishing on the rifle or doing permanent damage. I was thinking that the forward pins (5th picture, Red arrow) on the side may be able to be punched out and release the pin, however I am unable to get that pin to budge either. I'm attaching a couple pictures. I hope you can see and/or understand what I'm talking about. Thank you all in advance!
