I have just returned from a CQB match at Flag Raiders during the match my KJW M4 stopped working. I've never seen anything like it. The bolt carrier is jammed in just a little before the bolt catch. It will absolutely not budge by the hand of god could not move it. I've removed both pins out of the lower receiver releasing it. I've checked everything up and down. Made sure it had proper lube and nothing blocking or clogging anything in the lower or upper. So I slapped it back together for it to jam instantly again the moment the charging handle is pulled. The odd part was this gun was operating just fine for the chrony and sighting/hop up adjustment. After putting it together for the second time it will now not even come apart even when both pins are removed from the lower. Carrier is stuck inside the buffer tube and I've tried to use a punch to knock it out but it will not budge.

I need help, as I would like to go again next Monday. I'm extremely desperate.

Thank-You for your time. I would post pictures but I don't think it will do much good. But I will if you think it will give you a solution.
