New , first post, I want a 12.5 upper complete what company ?

I picked up a 12 inch upper from sulzar. Had to send it back due to poor grouping with both commercial and hand loaded ammo. Have read faxon had a bad batch of barrels that was sold. Only had it 2 weeks to test out before my back surgery so not allot of time to try other ammo. Sulzar offered to ship it back on their dime to check it out while I recover from surgery. Good price on the upper too.
