Extractor/Ejector kits: Factory vs. Kinney’s vs. Lumley. W/pictures.

[Mark611]

That sucks!!

[Dave Hoback]

Here it really shows the issue. He’s, I’m disappointed because I love the design & the attention put into it with the TiN PVD coating & the spring keeper tail. I think maybe it was just this specific kit with the Ejector I received, being machined a bit off. Because others are using them without the Ejector doing the same. And again, the Lumley Extractor, springs & the steel ball I received all work flawlessly. And I’m using the Extra for!

But in this pic can really see how far it’s able to lean and the shelf sitting high above the bolt face surface easily able to catch the edge of the hole.

Compared to the Kinney’s having the shelf extend down into the hole, the cutout for the stop pin is not machined too high so the shelf is not above the surface. Also, the diameter is a bit thicker on the Kinney’s at .099”, while the Lumley’s Ejector diameter is .0945”.

Wow Dave., that first one is way undersized,the ejector bore oversized or both I took a quick look at the Lumley's I put in the two bolt heads and neither one had nearly that much slop. As far a function after cleaning the ejector bores and the CLP treatment even the first pieces of brass ejected with the Lumley's. Did you happen to measure the ejector bore in that bolt head?

I'd rip one of mine apart but I fighting another demon at the moment. It seems my truck has a random parasitic draw which kills the battery in a matter of matter of few hours. When I say random it may kill the battery today, tomorrow or next week. No tell'n why or when! Dang new contraptions!:mad:

[Dave Hoback]

The ejector bore in the bolt head is fine. Both the factory & Kinney’s Ejectors operate normally. The second picture is the bolt head using with the Kinney’s Ejector. Can see it operates perfectly.

Ahhhh… parasitic draw problems! I was always really good at tracking those down in my profession as a master auto tech.

Dave,
Thanks for the info on bolt parts.
The ejector I got from Midway is like the one with the short upper section/long slot.
Potential to get hung up?

Rocketvapor, the link you posted is invalid. Regardless, won’t be able to predict correct operation from simply looking at the Ejector. Now, if it’s installed and looks like the picture I have with the Lumley installed, it certainly could. Again though, can’t see your link.

If you are referring to this Ejector, it should be fine. That’s a factory Ejector.

Got rid of the attachment (I think).
Here's the parts I have.
The 'Factory' Ejector from Midway shows the gap when installed.
Should be able to click for full size pic.

Yes, now I can see. Is that picture of your bolt head, or from online? Even though it’s above the surface, it looks like it’s running true. Straight in the hole. The Ejector in my Bolt Head was cocked at quite a bit of an angle causing it to grab the edge. All I can say is try it out & see. In mine the jam was immediate! And it was every time.

[Rocketvapor]

That's the left hand 223 bolt head that I probably won't use now that the 22N barrel came in and I have another complete 223 bolt.
Was going to use it without an ejector.
I wonder if a little radius on that edge would help?

[Dave Hoback]

Like I said, I would just try it. It’s not something to worry about. I mean it’s not a potential problem; if not something that will work today & become a problem tomorrow. If it’s a problem it will a problem immediately. It will either jam up or not jam up. It’s really that simple.
