Ok, so I had a stripped lower with 'US GOVT PROPERTY' on the roll-mark, and I wanted to change over the lower parts kit from one lower to another. The local gun shop who was doing the transfer on my new property marked lower offered to take my existing lower and new lower in the back, and swap over everything for me, for 20 bucks. I'm pretty busy, and time is $, so I agreed.
They put the trigger guard on BACKWARDS. How the hell do I get that roll pin out to fix this? Can't drive it through. I don't want to take it back and tell them to fix it, they clearly bubba'd it up the first time.

Try to find a sheet metal screw that will thread snugly into the center of the roll pin. Thread it in as far as it will go and then grab the head of the screw with a pair of vise grips. See if you can pull it out that way. If not- while you are pulling, have someone tap up on the vice grips with a hammer. I bet it will come out.

Yeah getting the roll punch out will be tricky. Probably need to drill a new hole... Or just leave it alone. Do you ever swing down the trigger guard?

Any idea what size screw? It's not like I can walk into the hardware store with my lower and try threading a few (not in the town I live in, anyways).

The pin is a split pin running a screw into it will try to EXPAND the pin. If you expand the pin to much you might pop a crack or break a portion of the ear off of the lower. At the least expanding it will cause it to grip the hole even tighter.
If I had one like that I would break out the Dremel and carefully sacrifice the trigger guard. |

If you were to carefully drill the pin to be flush with the trigger guard on that side, would you then be able to ‘roll’ the trigger guard out downwards?

Dremel off the trigger guard carefully. It is aluminum so will cut easily.
Roll pin should then come out easy. |

I’ll try the screw thing. I’ll let you guys know the results in a few days when I get time. It’s a 50 dollar palmetto lower, so not THAT worked up about it if it gets damaged, but I’d certainly prefer not to.

Just leave it, damage is done and you will likely ruin something trying to get it put. Putting a screw in will expand it and make things worse. The pin is steel, the lower is not.

Idiots should atleast give you your money back.
You know they had to cut the pin shorter before installing it, that should have been their first clue it was backwards. Leave it as is or use a dremel with a small cutoff wheel. Cut across the trigger guard close to the end with the pin, then cut through the guard and pin about half way and the loose part will fall out, Then grab the remainder and pull the pin through the hole. Be careful not to break the ear. As said above screwing a screw in isnt gonna work, its just gonna expand the pin tighter. Maybe superglue a small nail in and try to pull it. If it were mine I would clamp it in my milling machine and machine or drill the roll pin. If you know a machinist they could do this for you in about 10 minutes. Also why does it look like the trigger guard was milled down as in I see a shiny surface on the right side that was obviously milled and looks like it has sharp burrs on it. good luck. |

I didn't want to try the screw thing after several warnings, so i tried to superglue a nail in and pull it. Super glued it, waited 20 minutes or so. Didn't hold- nail pulled out without the pin. Now there's superglue gunk in there. I don't have a dremel (I know- everyone should have a dremel yada yada). Hell, maybe I'll just leave it, but it's always going to bug me.

Hmm, I just learned something. I didn't even know that was possible since I never tried it. Just tell everyone who sees it that it was done on purpose. If someone was going to flip down the trigger guard to use thick gloves it may actually work better that way since it folds away from the grip now?

I would just leave it alone and shoot it.
That said, I would try and get my money back and explain to them why you want your money back. I don't understand why you took it to a gun smith, it only takes about 5-10 minutes to put a LPK in a lower, maybe a bit more if you are taking one out and putting in another lower. |

Well guys, I have officially fucked it all up- broke off a 3/32" drill bit in the roll pin. So basically everything is great, and I've never been happier with myself/my luck.
Any ideas now?

It's honestly kind of funny at this point- although it's only funny because it's a cheap-ass palmetto lower. If it was an expensive disaster i'd be very upset, but I can get a new lower for 40 bucks and swap everything over (and do it myself this time).
Still, pretty irritated at the store for screwing it up, and irritated at myself for screwing it up even more. |

With the roll pin and the spring loaded pin being on opposite sides of the lower that guard is held on diagonal corners. I bet if you cut the guard in half right under the trigger you could rotate the two halves out of the lower.

I’d eyeball carefully, and center-punch & drill a hole in the other side. IIRC some lowers are made that way.
Punch the pin out, turn tg around & call it good. I would print a couple 36” posters with the first image and make a sign to give the gunshop - you know, as advertising for their “Gunsmithing Services”... 
ETA - If you’re willing to get/borrow a Dremel, the above is best option @ this point. |

Dremel cutoff wheel, cut the middle out of the back of the trigger guard from the inside of the guard. Tap the one side of the pin through the open side into the cutout area. Won’t be too bad.
