Encountered problems today

Check for a Primer that was blown out lodged in the gas tube on the BCG.

Clear and clean

I believe my gas rings are shot. Bolt moves very easily in and out of the carrier. Just installed a spikes bolt I had laying around and there's a huge difference. Could that be it?

Yes, but not normal for a low round count. However, gas rings are cheap and easy to replace. If gas rings are worn out it would short cycle, due to insufficient gas.
Gas ring info and video link.

Yeah I'm kinda shocked. Bolt will just fall out of the carrier

[SINNER]

If the bolt carrier is moving back far enough to begin stripping a round from the magazine short stroking is not your issue. The empty should have been slung out 1/2" of travel before it engages the next round.

Did someone say that they use MOBIL 1 on their AR? Actually doesnt seem like a bad idea...

That's all I used on my 6.8.

Haven't shot the rifle since but I'm hoping to get out this weekend. I will take some extra BCG's and buffers this time.

You sure?

If you read on there the motor oils generally have a flash point of around 450 degrees. At that point they can ignite. Also they have an evaporation rate that will make them thicker and stickier and hence will attract dirt and grime. That is unless you are stripping and cleaning every time, but over time it would probably wind up a big sludge particularly in a high heat area like your bolt and chamber, not to mention your chamber could burst into flames. :)

At least that's the non scientific conclusion I draw.

Harrison, the owner of ARP actually recommends it. At least, he used too.

I mistakenly had AARP in my head. I was like 'wtf do they know?'
