Looking for pic of CMP service rifle rule 6.2.3 example
I posted this is the "smithy" forum without much luck. I'm hoping it'll do better here.
I'm looking for pictures of an M-16/AR-15 service rifle showing the modification described below: Quote:

Sounds to me like it's basically a set screw that keeps the rear takedown pin in place so it doesn't "walk out".

Darthnul, I have not seen this modification but i agree with your theory. It sounds like the screw in question is threaded into the rear takedown lug. It draws the upper receiver down. This eliminates the need for the pins but the rule requires that the receiver retain it's standard external appearance so dummy pins must be inserted in the holes.
I remember a modification I did to and old H-Bar. I drilled and inserted pins vertically into the lower receiver and adjusted the height so when the rear takedown pin is inserted it takes out play between the upper and lower receivers. I don't know if it helps.
