Problems with F/A IMI Fullsize extractor/ejector probs...

[widz77]

I have an IMI Model B Registered Receiver complete conversion done by Billistics. It seemed to choke every mag in F/A. First it wouldn't always extract and would push another round into the spent casing, still lodged in the barrel. I cleaned the gun completely and bent the extractor a little so it would clamp harder on the empty case. This seemed to fix part of the problem, now every other mag will jam except this time it is jamming because an empty shell caseing is stuck in between the mag and the bolt. I'm thinking there is too much bend on the extractor or could it be an ejector problem? Is there anything I can look for to pin point the problem or is it all trial and error? Where can I get a new extractor and how much do they go for? How about an ejector?
Thanks for any help!!!!

Mags

First thing I would look at is mags. In my experience this seems to be about 90% of all problems.

I would also see if the bolt drags on anything.

Did you try different ammo? Sometimes that solves it.

Take a unprimed case and see if there is enough extractor tension to hold it in the bolt without it falling out when you shake it.

Maybe it just needs a tune up and you could replace the extractor and recoil spring.

I can give you more, but see if that fixes it.
