Try as I might, I think I screwed up the installation.

I slide the flared part down in the channel, and push it as far as it will go.

Then I assemble the disco and pin it in, then the hammer and pin it in.


Here is where it gets interesting.

When I cock the hammer ALL THE WAY back and press it down, then pull the trigger and ease it up, it will stay stuck down unless I squeeze the trigger multiple times.

Also, if I try to cock the hammer back while squeezing the trigger, it will not catch on the disco.

This would result in slamfiring and potential OOB incidents.

Please clarify which "it" you're talking about staying stuck down.  The hammer?  That sounds like a hammer spring problem.  The trigger?  Trigger spring problem.  Also, did you lubricate these parts at all?  I'd even put a little light grease in the pin spaces before installing the pins.

Yeah, the hammer stays down.

Make sure the trigger and hammer springs are installed correctly. Also the selector needs to be in place when doing a function check. Without the selector in place the trigger can be pulled past its normal travel range.

Classic symptom of hammer spring installed backward, or hammer spring bent...

The wide end of the spring should be inserted into the channel of the trigger assembly, not the narrow end of the spring.

He indicated he installed it correctly in the original post.  He said he installed "the flared end in the channel..."  My money is on the hammer spring being incorrectly installed or something wrong with the pins.

I never installed the selector.




Figured that the FCG would operate just like the one in my AKM.

Ahhhhhh.  Yes, that selector makes a BIG difference in how everything works.  Put it in and see.
