This is a new build that may fire 18-20 rounds well then stack the case 5 times in a row. So far have only shot PMC 147 gr. Have adjusted the gas. Going to try different ammo. I have a slow motion video I can send. We would love some suggestions. Thanks
AR-10 Extraction Issue
- Thread starter Josh Elam
- Start date
Home build?
I see a JP enhanced bolt in there. Proof barrel. Which I know for a fact works together.
What was your gas adjustment process?
Also, pull out the charging handle and look for a giant ass mark on the inside rear from the gas key. This type of issue is frequently caused by a mismatch of proper buffer and tube for the AR10 platform.

It has JP AR10 silent capture buffer h2, Vltor RE-10/A5SR, A5 Receiver Extension Tube, SLR titanium adjustable gas block.
It does lock back when single fed.
The brass shows witness marks from the extractor but not like it’s trying to extract with chamber pressure.
I can email or text a slow mo video to anyone.

Yeah I would start there.

"Receiver is designed to use the VLTOR A5 spring and buffer kit only which is sold separately."
Edited it, I just deleted everything I wrote.. that first picture now has me leaning towards under gassed. It doesn't look like it truly picked up that bottom round, but rather push it up through bolt drag to the case body.
(of course if it was a timing issue and the pressure was still up while trying to extract, it would do the same exact thing. lmao Okay I take back everything!

do you have the JP spring kit for the SCS? you might try other springs.
I built a 6.5 CM using SCS and the LMOS and its finicky to say the least. Ive seen guys ditch the JP stuff and all their problems went away.

Bolt comes back all the way.
Starts moving forward'
Case goes up more than right.
Jams in the front of the port.
My first thought is it's cycling too fast.
Since you said you have adjustable gas, I'd slow it way down first.
If it still does it, I'd think extractor/ejector issue.

As jimmy has stated it's either your ejector or extractor I've seen this many times, give JP a call and let them know what's going on and they'll send you some new extractor/ejector springs.
