PSA Premium 12" FN made CHF barrel. 11" SQR rail. PSA metal BUIS. Vortex SPARC. NiB bcg and BCM charging handle. I ran 40 rounds of assorted ammo through it without a single problem. I want to build an AR-10, so something has to go. This is a fantastic upper, perfect for your NFA lower or a pistol. $800. This is less than you could put this together for and without the three weeks of waiting. Please make all offers through coversations. This is available to OR and WA residents.
