That's exactly the same issue I was having cut my spring down too and now it's working fine.

hi I am having a few issues with my new dedicated cmmg mk4 the first time shooting it with the smith and wesson mags and better mag adapter it fired the first 6 rounds of blaser without any issues then the bolt started to lock back on a full mag simply pressing the bolt release chambered a fresh round and allowed me to fire another round but this keeps happening I can't get through a full mag with out this happening about 3-5 times also I'm getting some very light primer strikes that fail to fire. when you manually cycle the gun with the charging handle it feeds and ejects fine it seems to only be happening when firing. I am positive I have inserted the adaptor correctly as when it's working I can sometimes get off six or more shots back to back without any problems.I haven't had a chance to shoot without the adapter using the cmmg mags yet unfortunately. If anyone has any ideas that might help I'd be very glad to hear it. thanks guys

Just wondering if anyone can give me some feedback about installing an aftermarket metal charging handle on my cmmg . Have you had any problems with stuck cases ect. many thanks

no here you can cut any rifle barrel down to a minimum of 12 inches without any paperwork there aren't any tax stamps for suppressors either

Hi from the UK just picked this up today the barrel has been cut down to 12 inches and re threaded the lower is a DPMS i can wait to get out and shoot it.

Hi all I'm tom from across the pond I'm looking forward to reading through this forum
