Will do.

I might tackle this one myself though. What's the worst thing that could happen? I f**k up a perfectly good disconnector? [Coffee]

(Or really screw up and have the thing go "full auto" [Help])

I just experienced a similar situation in building my second AR. After installing the hammer and moving the hammer back with my thumb, I found that it makes a significant contact with the disconnector 'beak' before continuing back and locked. My first build just barely brushed the 'beak' before locking the hammer back. I did have another new LPK (also from PSA) for spare parts. I swapped out the hammer and now its like the first one...much smoother. The first one must have been misdimensioned?

I'm hoping the lesser contact with the disconnector 'beak' is the proper operation... As now I'm not certain which is the preferable operation/engagement.

You need a touch more engagement than than just brushing the beak. You want to err on the conservative side, you can run into a doubling situation especially if you are trying to feather the trigger.
With the trigger depressed you want AT LEAST a 1/16" and preferably a decent bit more disconnector engagement.

Thanks kind sir...after reading your quick response I just compared my two builds with a factory Bushmaster and they seem identical.
If I have any further doubts I'll probably make an appointment with you and bring them up there for you to evaluate.

Thanks again,

And doubling ain't no fun on a Big Bore AR..........[LOL] (Private joke, Bert Knows the meaning.)

Finally got a replacement hammer for the bad one from PSA...they didn't want the original one.
The below pics show the bad, original, one on the left, and new PSA one on the right. (one on the right has some small squares with an "S" in them)Attachment 45213Attachment 45215

What kind of a mess is the one on the left? Can you post a side shot?

You did not get the memo? That is the UWE hammer with ultra wide engagement surfaces. For the true "operator" to keep on going when his pins fall out. [LOL]

Looks like a bad casting to me. China is not known for QC. [Flower]

I forgot, that's the "Tier One" model.
Muzzies fear it's presence and women spontaneously orgasm at its mention.....
