I bought an 80% lower and milled it with the jig. Rather than buy more parts, I decided to use parts from my dpms to affirm everything was working ok before ordering new parts.
While drilling the safety selector hole, I managed to tilt the table a few degrees. After using the drill bit to ream the holes by hand until the selector fit, finally.
Now, when the parts were re assembled, the selector has very little resistance between the safe and fire positions. My first thought was that the mis aligned holes are the problem. After a bit of thought, ?it seems to me that there has to be more to it than that. Given that the receiver is aluminum, if friction in the hole is the only thing holding the safety selector, they would wear out in a few hundred rounds.
Also, the switch can be moved side to side about .015"
What did I do wrong? (besides thinking I could do this myself)?
