I just assembled my first lower. Aero stripped lower with an LPK from PSA. Everything went very well for my first try except, the pivot pin isn't moving. It wiggles a little but it won't freely "slide" even with some pressure. I realize the detent's job is to keep it locked in but it should slide with some pressure yes?
I am nervous about using more than my finger pressure at this point, any advice or wisdom is appreciated. |

Let me clarify, I am not nervous about working it...I didn't want to jack anything up. I appreciate the advice here, thanks. Just tap it with a small hammer.. or screw driver handle... Then drop some CLP into the detent channel. Almost all pivot pins start out like this.

Sorry for the stupid question, really was thinking I f$#@ed up my first build and also didn't want to scratch the receiver. |
King of Wrong tool for the job here!!
| I have had 2 rifles where the pins were initially so tight you could not push them by hand. I had to use a punch or similar tool. They all loosened up with use. This is normal. I think manufacturers are tightening tolerances so things don't get too sloppy over time. |

Always better to use caution and not force something than to force something and break it and have to replace or repair. I too have had several upper lower combinations that were super tight and needed a tool to open the pins, they loosen up over time.....the nature of the beast. |
