AR-10 problem

[patience0830]

Well he did something with removing O rings from the ejector and was able to manually cycle a full mag through it. So it would appear at the moment to be related to the ejector.

WITF?

Now I gotta take mine apart and look for O-rings.

Are you talking about O-rings in the extractor? These?

Those would be the only ones I am aware of.

I forgot about that one.
How would that interaction keep you from cycling the action?

PSA usually sells assembled uppers that are headspaced. PSA AR-10's also are not standard. AR-15 stocks, carry handles and hand guards fit them because they are dimensionally closer to an AR-15 than a Stoner AR-10.

I assume the combination of the spring, rubber spring plug and o-ring could cause too much extractor tension for it to pop over the case rim...which could also bring into question the buffer spring strength which has previously been mentioned.

Could be. I have never had one apart so I may have used the wrong term and part

I ordered 4 BCG's at one time from PSA, one I had to send back as it had the same extracting problem.

How full is the mag? Try running it with 2 less rounds in the mag. I had an AR that didn’t what to peel off the first round from a completely full mag, but load 1-2 less and it was fine. Sometimes squeezing in that last round can make it tough to get the first round out.

Has the gun even been shot yet?

No he hasn't shot it yet. This was built under the radar, as I understand his wife doesn't yet know he had it built. I believe he had it assembled last summer

I just worked on a friends Anderson AR10 that had similar issue. I had some extractor springs and O rings in my spare parts marked for AR10. The factory set up had some time of epoxy cake in the inner spring, restricting its movement. I replaced the extractor spring and rubber bumper and o ring. I used one print instead of 2 and it worked great. I think it was way too much tension on the extractor.

Man I have no idea how some of you guys live having to hide what you do from the spouse.

Understood CM. Momma and I have it worked out so that we both are able to buy stuff we want. Sure she gives me grief every time I bring home a new gun but mostly she just rolls her eyes and sighs. Now my daughter she always gets excited and wants to check it all out before she asks do I get to shoot it first?
