WTT an AR upper chambered in 556. Started life as a PSA upper, but I upgraded the barrel to a Faxon gunner to improve weight and accuracy. Shoots great, consistently sub ~1.5 MOA with bulk ammo, occasionally I can get sub MOA out of it. Open to a variety of trades, let me know what you have. 9mm or 223/556 ammo would be my first choice. 10/22 is a close second. Text is best to reach me, 512 2eight9 7200, thanks
