I just got my first AEG about 3 days ago, it is an echo 1 G36c cause I couldn't quite afford the the src or kwa. It worked wonderfully at first and it's an insane amount of fun to fire, but then it suddenly started having issues today. It shot fine for the first two days but then today when I started practice shooting again the problem began. What happens is I shoot off a round or two and then the gun begins to dry fire as if it's empty. It continues to dry fire or once in a while a bb or two will just fall out of the barrel with only enough force to go about a foot or two. Occasionally it would start shooting just fine again and I could go through about 60 BBs before it would start acting up. I am using high quality biodegradable BBs some of the time and echo 1 some of the time. Both are 6mm .20 weight. But I am not mixing them in the same clip. I've wound the magazine (the high cap that came with the gun) and it has resistance and I know there's plenty of ammo in there. I've tried the unjamming rod and as far as I can tell all that it's touching when I put it down there is the internals because I don't feel any pellets or any resistance until it's almost all the way in there and nothing dislodges any time I do that. Although I could be hitting a BB down there and just not know it but using the unjamming rod doesn't seem to cause the problem to clear itself up any faster. If I pull the mag usually I notice 2 or sometimes even three BBs sitting loose on top of the magazine (I'm sorry I don't know the term for this part of the mag) and I'm pretty sure there is only supposed to be one BB sitting on top of that loose and the rest are supposed to be under that lip that holds them down. If I press the release on the top of the mag about 30 pellets fly out of the mag, so i know the spring is wound and the side of the mag that feeds is full. I hope I gave enough information here. I'm new to the sport so it very well could be something very basic that I just don't know. Overall I would say today it would misfire(dryfire) about 30% of the shots I took. If anyone knows what is happening here please let me know.
