AR15 jam

semtex:
Fix it before it breaks. Especially if you want to use that weapon for anything but "target practice."

semtex:
OP, a simple test to see if it is a gas system issue is:
Load one round in the mag. Fire. Did the bolt lock back? If not you probably have a gas problem.

Also Check:
- FSB for wobble
- Gas tube for propper fit and deformities
- Gas rings on bolt
- Carrier key: screws tight and staked? And loosness in carrier key?

If the gas system is good to go, then I would look at the ejection systems.

SeanN:
Any updates on this? Has the problem occured again?

maanbr:
Haven't fired it lately, but the few mags I ran through it after the jam had no problems.  I honestly think it was just one of those random jams.  I was just wondering the cause of it and how many others had seen the same type of one as I hadn't in 12yrs of shooting AR's/M16's.

SeanN:
Glad it seems to have fixed itself. I would suggest, if it happens again, you do what one of the other members suggested and make sure your extractor spring and o-ring are strong enough and if not purchase Bravo company's 'extractor upgrade'. They make great parts.
