| I just finished my 1st 80% lower from EP Armory. After installing the trigger group and the hammer, the hammer would drop only halfway. It felt like it was catching somewhere. I took a dremel to mill out a bit further and breached into the magazine release well. Now about 1/4" of the magazine release well is exposed. I can see the spring. Obviously the resistance is either from the floor of the lower not being deep enough or the side of the well. My question is...since I screwed up and milled too much material from the lower, exposing the magazine release spring, is the lower still safe to use? I know that there is not much pressure going on in the lower other than at the buffer tube area. Any insight would be greatly appreciated. |
| Every one of my 80 lowers plastic and aluminum have a punch through on the wall by the release spring. The Polymer 80 instructions say that this will most likely happen as the Mil Spec dimensions leave just a few thousandths there. It does not affect function at all. |

Quoted: did the same thing here too  , honestly i was too embarrassed to post a question on here to see if anyone else had done it,i figured i wouldn't affect function though Like trying to tell the judge one he has never heard. I can guarantee that someone else has had the experience before. That is what makes this forum so great. |

I milled a bit more from the sides and underneath and the hammer still has resistance. I found that it is rubbing on the part of the trigger that catches the hammer in that tiny lip. after the trigger is pulled the hammer goes forward about halfway and then for some reason it rubs that part of the trigger. I realized this after closer inspection and there is evidence of wear from the hammer rubbing. when I put the trigger group and hammer back into my RRA aluminum lower this doesn't happen anymore. I am thinking that maybe the holes I drilled are slightly off. I hope I don't wreck the trigger but after playing with the hammer a ton it falls much easier, but still has some resistance at the halfway point.
Thanks to everyone for their insight. I am trying to learn as best I can. Not having a drill press or end mill makes things kind of risky. |
