FTExtract?

Maybe i'm pointing out the elephant in the room, or maybe i'm just ignorant, but aren't both the description of the problem and the "bulge" on the bolt, pointing to the extractor? Perhaps it's just worn out... Obviously a new bolt or BCG would resolve it, but they wouldn't necessarily be required to fix it...

I wouldn't know. I guess I'll put a few new extractors in my order also.

There is a reason I keep some SA surplus on hand. Years ago I tested some of the cheaper ammo just for fun and had a few that were not always 100%. I would check everything and it is always a good idea to have a sare parts kit on hand. The SA ammo is loaded hot so I know that if it will not cycle on that then there are issues. New rubbers and spring in the extractor will not hurt if the claw looks OK.

I wish I would have known the rifle had issues, I have a spare bolt at home. I probably won't head back to shoot for awhile so it'll remain a mystery for now. I'll get the parts ordered and report back after I try and do the repair.

Clean the bolt and carrier. Reassemble it without any lubricant and extend the bolt fully. Set the BCG on the face of the bolt vertically. If the rings have sufficient tension the rings will support the weight of the carrier, if not the carrier will drop.

Easy to test this at home.

So I did the test and gas rings can barely hold up the carrier if I hold everything just right, so they're on the verge and will be replaced. The extractor also seems week compared to the spare bolt I have on hand so I'll get a few replacement springs. Extractor itself looks okay, should that be replaced just due to general maintenance? And what's the deal with this replacement "O" ring? Do you guys recommend those?

[BPTactical]

The o ring is a supplement to the extractor spring plus it acts as a buffer between the extractor and bolt so you don't hammer the extractor. Numerous sources market "extractor upgrade" kits that include a stiffer spring, revised buffer (the small rubber slug in the spring) and the O ring. Might as well upgrade your entire stable.
Rings are shot, you shouldn't have to hold the BCG "just so" for it to stay extended. Don't worry about the one piece rings or any hoopla, standard rings run just fine.
Both items are a normal wear and maintenance item.
Unless the extractor is chipped, cracked or bent they usually don't require replacement.

Thanks again Bert, I appreciate your willingness to share your knowledge. I'll get some parts ordered.

I'm sure it's a combo of things. The gas rings are worn and the extractor doesn't SEEM have the tension on it that my spare bolt/extractor has so I'm sure that's the issue. Parts are on order! Probably won't go back to shoot for another month though.
Thanks everyone for all the replies.
