why did you change the hammer in the 1st place? how high does the ejector lever sit in the bolt head......look when you pull bolt to rear and see where ejector lever sits......it should fill the space it fits into

Do you still have the rifle hammer spring in?

Also check for slipped sear spring or a burr (probably not it but get a burr at ejector spring noch).

Ejector lever is in the designated groove, its not havin problems ejecting, the rnd thats left in the chamber with light primer strike is a UN fired rnd everytime. What would make it run smooth 1/2 way threw the mag then all of a sudden run erratic (Spelled right?) then leave a live rnd in chamber? Sounds like timing or headspace to me but the bolt gap looks good?

ejector lever height is a good check for the need of the shim.......did you check your firing pin spring? Is the channel in the bolt carrier where the locking piece and firing pin fit gunked up?

 

[BeltfedMGs]

Nope not gunked up, pretty clean.

I know this is a really old thread, but its worth a try...

Did you ever figure out what the problem was? I am experiencing a similar problem. RDTS 4 position pack on a DJ Getz reverse stretch clone. Pack fits nice and tight. Things run well for X # of rounds in a mag, then it stops. When I cycle the gun a bullet with a light primer strike comes out. I've tried multiple HK mags and 3 different types of ammo

Just in case someone finds this in a search years from now: I replaced my hammer spring with an enhanced version from hkparts and replaced the firing pin. On close inspection it looks like the surface that is struck by the trigger pack hammer arm had "mushroomed" a bit on the firing pin ... perhaps from the increase in force from using a rifle spring instead of a 9mm spring?

I haven't been to the range to test this out yet. I'll try it out this weekend and report back for reference.

I tried it out and still the same problem. I decided to send it off to Ralph @ RDTS to investigate.

Be sure to give us the update.

It was the trigger pack after all. Ralph from RDTS said that the "Hammer welds" were broken. I got the repaired pack back yesterday and hope to try it out this week.

Broken hammer welds. Haven't heard/seen that one. Man I wish we had before & after pics. Regardless ..,thanks for the follow up.
