Ok so I have a factory SBR CA89. I have had my share of issues. FTE (extract and eject), double feeds, pushing the bullet back into the casing, you name it, I probably had it.



The bolt was out of spec in that i could not swap the extractor (new one wouldn't fit) but i was able to swap the spring. That didn't help.



I have now swaped the entire bolt assemby, ejector lever and ejector spring. Those that have been there before, am I missing anything? Are there any pitfalls with my swaps? What are my odds this thing runs like a champ now?



The only part I haven't swapped is the mag. I am still using the ATI mags. I will have access to some HK mags Friday to try as well.



I want to know how high my expectations should be at the range Friday.



Thanks guys!

One other thing to check is the trigger pack hammer spring.

The SW5 that I once owned had a G3 hammer spring in it.  Every round was a failure to eject with a failure to extract thrown in.

Thanks,

That was the fix for mine.

magazine and hammer spring should do the trick

Hey prib,



Don't suppose you know of anyone local in the TC that stocks those springs. I am starting to think that may be the issue. It makes a lot of sense.



Thanks,

skippyputz,

HKparts.net is where I get parts for my CA89 pistol. Similar issues. I replaced the ejector, ejector spring,exractor, extractor spring, and hammer spring. Took care of all of my problems.
Now, I am just waiting for my SBR stamp.

Yeah thats where I ordered the stuff from. Was hoping to save on shipping since i just ordered but eh, oh well. Its going to be a fun little toy if i could only get it working! I have wanted one for years and finally saved/spent the money, I just want it to work. I wish now that I had bought some of those parts kits they were blowing out at the end. I kinda want a .40 too.





Thanks again guys!

I had a CA94 with the same issues. I switched out the complete bolt for a new one from Hkparts.net and used only HK factory mags. After that it ran flawlessly. I wish I didn't sell it.
