Spire Machine Trigger Guard roll pin

This pin will certainly get you there if you don't want to buy a whole "Oops" kit for your AR-15 lower build, but I take issue with the Product Feature of "Perfect Fit". My first lower that I assembled two years ago I built off of an RRA lower parts kit, and the trigger guard pins for that slid in like butter through simple hammer use. This pin, for whatever reason, was the most stubborn portion of the entire rifle assembly process. It was ever so slightly larger than the pin hole on my lower, and as I hammered it in it almost immediately began to deform. Now I had a trigger guard pin that was halfway into the lower and warping. Luckily when I took it out to my father in law, he grabbed his punch set and we were able to sink it the rest of the way in, but even then the pins deformation left one end super shiny. Nothing a Sharpie can't fix, but overall this was a bit of a pain.

Easy as 1, 2, 3
