So, I want to build my own AR. Was planning on doing so in the future when I was done with school and off workers comp. So my friend bought a couple stripped lower receivers the other day and found the one he liked. Has asked me if I wanted one. So I jumped on the chance. Its a brand new, still in the box spikes lower receiver with the bullet markings. Never been used. He also have me a nice collapsible stock and a carry handle as well. I was BSing with another friend and told him about it and he gave me A front grip and a fore grip. I know I need a whole lot Kore, but hey. Every thing I've gotten so far is free. Pretty cool in my book. So I am checking out other parts to price stuff out. I know I don't need the best of the best but damn..... I didn't realize how expensive bubblegum what for these guns. Hopefully I can finish it within the next year.being on workers comp with a fixed income blows. Any one know of good places that are relatively inexpensive to get ar parts from?
