I would like sell my Stag Arms upper half to help fund another project I'm working on. The Barrel is stamped .556 and comes with a quad rail that I have added. It has about 500-600 round through it and works flawlessly. I can add pictures later if needed. They are going new for around 550 so I think 450 would be a fair price. I would like to sell it face to but I'm willing to send it if you pay the shipping. As far as trades go: I'm really looking to sell it but I may be open to what ya have. The worst I can say is "No Thanks". Let me know if you have any questions. Thanks for looking!
