Light strikes??

[yrone]

Took the AR out to the range today and had problems right off the bat. I'd chamber a round from the magazine, fire, it would cycle another round and then act like it wasnt cocked. I'd use the charging handle and eject the live round that didnt fire and strip another one from the magazine and it would fire. The ejected live round had a light strike on the primer.

Strange, so I get it home and the bolt is dirty as hell! The last range day I went through a hundred rounds of wolf and did a light cleaning of the chamber but nothing on the bolt.

Any ideas, do you think it will run now since I gave the bolt a thorough cleaning? I mean even inside the firing pin channel was dirty!! Never seen anything like it.

******** UPDATE

Problem turned out to be a missing disconnector spring! Without it it was behaving in the manner described above. Also note that the rifle went full auto for 2 rounds which was funny :supergrin:

Dimpled primers are normal when a round is chambered and ejected in an AR. The firing pin free floats so there is nothing to hold it back, such as a spring, when the BCG goes forward.

Run the troubleshooting checklist, and post the results. Also, include the pertinent data on your gun/ammo/misc combinations as found in "read this first thread."

Since cleaning it theres nothing that sticks out from the troubleshooting checklist. When dirty I noticed that the cam was hard to get out and the movement going from front to back was harder than it seemed it should be due to crap in/on the bolt and hard to get out.

The upper is a Rock River CAR A2 and the lower is a newly built Stag Arms. I'm really leaning towards the WOLF ammo. Dirty dirty dirty! Was just wondering if the symptoms pointed to anything obvious besides the dirt. Im going to take it out and run it again in a week or two. Will post followup.

THANKS EVERYONE!
