I have 2 billet uppers, and 2 billet lowers. They are made by TNW out of vernonia. I am looking to sell them in 2 sets (each set with 1 upper, and 1 lower just to clarify). These are not top quality billet pieces IMO. I was going to build a varmint gun off them, but they just aren't good enough for me. They would however make a great lower budget AR. I had a nylon tipped set screw added that puts tension on the rear takedown pin boss on the upper. You tighten the set screw by removing the pistol grip and use an allen wrench. Should have pictures up this evening sometime. Once again, these WILL have some slop, the set screw does a decent job minimizing this, but they are still being sold AS IS. I am asking $200 for 1 billet upper/lower set. I have 2 sets available. Thanks
