Thread of the magazine release pivot screw?

TooTech · January 06, 2001, 22:06

I can't get the mag release pivot screw to bottom out on my Imbel receiver. The screw is out of an R1 kit. Before it can bottom out the screw becomes REAL hard to turn, leaving about a 1/16" of the head about the receiver surface. There is plenty of depth in the screw head inlet (tested by reversing and inserting the screw head), and the hole on the other side of the receiver is clear (tested by pushing screw end in from other side).

The leading threads on the screw are shiny, and I have a feeling I need to chase out the threads in the ejector block. Or am I missing something?

Otherwise, what tap do I need to clean out the ejector block threads?

Thanks!

10/32. drill out with the proper size drill, perhaps a bit of mis-fit on the ejector block, a small problem. D.

Thanks Derek, worked like a champ!

I own exactly ONE tap, and it just happened to be a 10/32!

How's that for serendipity?

I ran into this exact same problem with a recently-manufactured IMBEL type 3 metric receiver and a Chilean IMBEL parts kit.

Rather than drilling on the receiver, I think I'll just file the leading portion of the threads on the pin. Not like you need a lot of thread-engagement for securing this screw.

(The truth be told I DID WECSOG the screw head, as at first I thought the screw head was slightly to large to go into the countersunk recess. Now I have a very "sleek" screw-head for this part.)
