I’m already armed and provisioned, but I’ve always wanted an AR pistol - preferably in 300BLK. I’d like to feel like I did it on the cheap. I own some tools and I’m handy enough.

Will I be saving money, this day and age, rolling my own? What’s the most cost-effective way to build a dependable platform? The way I see it, the 80% lower and 3D printer routes are only cheaper if I’m building several lowers. Is that right? I see blem lowers from Anderson for pretty darned cheap, but then you have to pay shipping and the FFL..
