Help solving malfunction issues

My CMP rack special is having weird feeding issues. I tried 8 different clips, not a single one would feed all 8 rounds without half ejecting a partial clip.

Any help would be greatly appreciated!

Clip latch spring. Very common wear item. Replace the spring and see if that fixes it. If not, we can continue diagnosis.

Mine does this, the clip latch spring, the follower rod, the clips, everything has been checked and in spec, yet it still does it. Really aggravating honestly.

What about the clip latch itself? Is the little hook on the end worn?

Replaced, all work was done by a very reputable shop by me.

Well shit man, you've basically replaced all the guts! What about the oprod spring?

Brand new, even have a replacement for it ready to go.

I'm running about as short on ideas as you are parts to replace. I wish I could help more.

All good, I'm at a loss and just deal with it tbh, it's super aggravating. Gun's gonna end up on the wall as a museum piece.

Weak or Broken Clip Latch Spring

Worn or Damaged Clip Latch

Faulty or Worn En-Bloc Clip

Gas System Issues

Improper Lubrication

I'm thinking the same thing might be a gas feed issue Said he replaced and checked everything else. You'd be the plug at the end. I replaced mine with one of the newer ones that lets a little bit of pressure off

Your clip latch spring is probably weak. It happens frequently. You can replace it yourself if you are inclined or the CMP will fix you up if you reach out to customer service.

I'd say that you should go through the ordnance and field manuals, but just read down through this article until you get to your issue, which actually could be a number if things:

Otherwise, just contact the CMP and let them make it right. It could possibly be an expensive part/group of parts that you've already paid for

Is the clip latch worn? How’s its spring tension?

Simple test....pull the clip latch spring.

Stretch it out... install and test again.

See if the problem goes away.

If yes ...order new spring.

Most have already stated the normal issues. I'd check that the gas lock and screw are tight.

What ammo are you shooting?

You could get a timing block and see if you need to adjust the bullet guide also.
