I took my DPMS 6.8SPC M4 Upper (on a Stag lower) out to the range today and had a major malfunction. The Bolt seems to be completely stuck in the barrel with a LIVE ROUND. I am unable to get the charging handle, to budge. I was able to separate the upper from the lower so it is a little safer with that live round stuck in there. I can move the bolt carrier just slightly but the bolt it’s self appears to be stuck in the barrel and won’t allow me to get the carrier out.
When the Upper and Lower were together I tried to tap the buttstock on the ground to see if that would free it up but all that did was break my RRA 6 position buttstock.
Any ideas on what to do?
UPDATE:
When I got home from the range I was still unable to get the bolt out of the barrel, so with the upper seperated from the lower I was able to place a paint stick on the bolt carrier and tap the other end of the paint stick with a brass hammer. This got the bolt and carrier to finally release. I inspected the rifle very carefully and saw no sign of damage. I removed the bolt from the carrier and inspected it. The bolt was extremely dirty which surprises me as there is no more than 60 rounds through this rifle. I completely cleaned the bolt and carrier and put it all back together. It seems to function test fine. All I need now is a new buttstock.
I guess I'll try this upper out again tomorrow on a differant lower.
Anyone ever have this happen to them before? Any idae what might have caused this?
UPDATE 12-13-2005
I received my rifle back from DPMS today. They found that the Bolt had a "ring" on the face that was shaving brass and causing a head spacing problem resulting in FTF's and FTE's. They corrected the problem and I should be good to go. I'll go to the range on Thursday and test it out along with the Siver State Armory 6.8SPC ammo.
