Poor quality - Live Free Armory LF19 Combat Series Pistol Slide w/ RMR Optic Cut for Glock 19

I wanted to support a veteran owned and operated company that keeps everything in the USA but after having a few of their products I won't even try them. Had to send back due to lack of threads for sight mounts, only .0065" thread engagement. The replacement was just as bad. Finish is also poor. Came scratched just from the packaging. The burrs didn't bother me since I assumed it wouldn't be deburred. The more I looked at it the more issues I noticed. I bought 3 items from them and had to warranty 2 of them before assembling and sent the 3rd back. Save yourself the time and money and buy Glock. I would have given 1 star but live free was fairly quick with exchanging the slide. I'm very surprised optics even sells these products.
