Double, Triple Feeding Problem
Hello,
I have this double / triple feeding problem with my CA m15a4 carbine. I tried to open the gun and pull out the inner barrel. I did some inspections with the hop assembly and found out that the hop-knob is already flat. I've tried to replace the hop-knob with a wire insulator cut with the same size as the hop-knob and with the same thickness but a little bit hard to flat.
I put everything back and did a test fire. All is well and there's no double / feeding issue anymore.
After several weeks, the problem occurs again. I tried to check the hop-knob again but it does still looks good. No signs of flat. Anyway, I did changed it again with a new wire insulator same with the one I've used before, put everything up back and when I ran a test fire, the problem was still there.
What more fixes can you think to solve this problem? Thanks.
