With the full enbloc fully inserted down, the oprod needs a slight bump to get things going..
Ops Normal. Depends on a lot of stuff like clip tension, cartridge case friction, op rod spring strength, etc.

What you're really concerned with is "Does the Clip Latch engage and the Op Rod Catch release at about the same time?" If everything's working right they should. You shouldn't have to jam the clip way down to get the clip latch to engage nor should the bolt come forward (op rod catch release) before the clip's down far enough so the bolt can strip off the top round.

It's educational to take the Receiver Group out of the Stock then load a clip of dummies. Watch how as the follower goes down the Op Rod Catch starts to pivot until it releases while the arm on it simultaneously stops pushing on the Clip Latch allowing it to engage the clip.

I'm a bit unclear as to the sear/trigger handoff/disconnect, though....Is there a standard function test for this?

1. Ensure weapon is unloaded
2. Cycle Bolt to cock Hammer
3. Engage Safety
4. Squeeze Trigger - Hammer SHOULD NOT FALL
5. Release Trigger
6. Disengage Safety
7. Squeeze Trigger and hold back - HAMMER SHOULD FALL
8. While holding Trigger to the rear cycle Bolt to cock Hammer
9. Release Trigger - HEAR "CLICK" as Hammer is handed off from Sear to Trigger
10. Squeeze Trigger - Hammer SHOULD FALL

Also educational to do this with the Trigger Group out of the weapon. Pad the inside front of the Trigger Housing so it and the Hammer don't get beaten up. Then watch how the trigger and sear work with the two sets of hooks on the hammer to ensure semi-auto operation as well as produce a two-stage trigger.

I think it's all pretty neat and gives you a better appreciation for Mr Garandicon's genius
