Decided to give one of these 80% lowers a shot and build an AR pistol in 300blk. Honestly, I guess I was somewhat lured by how simple all the different vendors make it seem. It's not that the work is difficult, but it is a great exercise in building patience. Having never really "milled" anything since high school shop class, over 30 years ago, I was a bit anxious to say the least. I used a 10" tabletop drill press and a cross slide vise, which I may have to tear apart and clean up as it was rough too say the least in its motion. Even with my inexperience, I am quite pleased with the results, interior walls of the fire control area are nearly as smooth as the interior of the magwell which comes already milled. The trigger hole was a bit rough, but a little work with the dremel cleaned that up. will I do another lower, definitely. Did I learn from this, without a doubt. Now the wife and daughter want to know when I am going to finish the rest of the build so they can go shoot it, this was supposed to get me something to shoot cause they hog the other ar I assembled... Looks like I will have to build at least one more, maybe .308 this time???
