CMMG 22lr Conversion Kit Problem

[fusionstar]

It seems my extractor is out of spec. It extends pass the bolt face I would say 3 hundredths of an inch. Which is ALOT.



So the problem is.. it does not grab the rim. I have never shot this one yet. But even in testing, I cant unload a round from the chamber because the extractor wont grab it and pull it out.

I think they drilled the hole in the extractor too far back. Because even the notch for the dust cover is off by what seems the same amount.


I have photos and a video below in a few minutes..


Still uploading videos onto youtube

To me it looks like the extractor spring is a little on the wimpy side and like you said the extractor is a little to fare from the face of the bolt. I have never had any problem with the kit I have. Have you contacted CMMG for help or a replacement.. Good luck..

I just looked at mine and the extractor sits about the same distance away from the bolt face as yours does but it grips the round. May be it is the spring?

I'm having a similar issue with my conversion. I suppose that replacing the extractor is the only way to go.

Have you shot the thing yet?

My Spike does not extract a live round (as you described above), but in live fires, it functions correctly. I contacted Spike, and all they say is that it is normal. I don't really buy that, yet, there is nothing I can do.

Im sure live fire will function due to the recoil. But The fact that I cant even unload a round from the chamber is one thing.

I dont think its the extractor spring, Because the round gets pushed out of the bolt face where the rim is supposed to seat flush in and the extractor just has nothing to grip..

It could be the chamber adapter. Maybe the slot for the extractor was cut too shallow?

So.. maybe its 100% live fire.. but what if I want to get rid of a dud or a live round. I dont want to pluck it out with a pocket knife again.


Its just odd if that was built in.. We'll see.. I have yet to get to the range with it.

Sent it in to CMMG to have them look at it. Hopefully it gets fixed or replaced

Welp, they resurfaced the extractor and refinished it. Now it extracts live rounds.

i knew it wasnt normal.

Cost 8 dollars to ship it to them and 2 weeks.

Im pretty happy.. but the finishing on the adapter is horrendous. Time to go to the range

was that a live round in those videos? When trying to extract a live round when the kit is outside of your gun be carefull. When its not pulling the charge handle that recoil spring moves VERY fast in closing that bolt faster then when its in the gun. So fast in fact that it can and WILL cause a slam fire

Ask me how i know!! My work bench still has the hole to prove it It went through the bench and hit a wrench in the drawer underneath and stopped. Since that day i dont play with ANY live ammo at home.

My kit was having the same problems. I did a lot of research on ARF.com on spikes and CMMGs forums and did some chamber and feed ramp polishing. The thing extracts live rounds now and runs %100. Not even 1 FTF or FTE out of 2 bricks of federal

Yea I had that same scenario in my head. Which is why I didnt pull it all the way back outside the gun. I could of just replaced the extractor with a new one. which is 10 dollars.. but I think it was worth it to test CMMG's customer service.

I had almost no contact with anyone.. but things went smooth. I guess I cant ask for more.
