I just assembled my first lower and everything works great with one popssible exception. The safety functions properly and clicks on & off easily with the bolt forward, but it is very difficult to engage if the bolt is locked back. It seems odd as none of my other AR's are like this. Is this an issue? If so, whats the best way to fit the safety / trigger to fix it? Thanks for your help

Quoted:
What kind of LPK do you have installed in your lower, and what kind of bolt carrier do you have? The LPK is RRA but in place of the RRA FCG I installed an ALG ACT trigger. The complete upper (including the BCG) is RRA. I did not want to damage the plating on the ACT trigger so I removed a small amount of material from the safety and it works fine now, so I think the problem is solved... |
| I just talked to ALG Defense. They told me the oversized pins they ship with the trigger is causing this. They are working on new coated pins and will ship them to anyone who has an ACT trigger in a month or so. They said to use the stock pins for now and it should work fine. |

I just bought and put mine in and it works fine. I don't see how over-sized pins cause the trigger to be in any different of a spot to make that kind of change. Maybe they caught it before I got mine. |

He said it wasn't happening in all the triggers and the tolerances from receiver to receiver and lower parts can make a difference.......we're talking thousandths of an inch here. I am about to try my stock pins to see what happens. He said to not mess with the safety as far as sanding/filing it down (probably for liability reasons) but suggested I could stone the back of the trigger area that makes contact with the safety/selector area. I will post back in a few. |

Yep, it works now!!!!!

If ya think about it, the smaller pins allow for just enough slop to give the trigger room to stay off the selector switch and not rub. |
