Great product. Smooth and accurate. No issues at all. Must have 1000 rounds through it now with now issues.
Purchased this setup in a combo w/ bcg, ch, and a lower build kit for $500 in December 2016. Slapped some MBUS and a Nikon 300 aac reticle scope on it and off to the range. Great upper right out of the box. Smooth and accurate, no issues cycling with any ammo from 115 gr to 147 gr so far. 130 grain match ammo is sub inch groups at 100 yards easy.

Shooting Remington hog hammer ammo it dispatches 200 lbs boars with one shot kills. I have since removed the Nikon scope and replaced with a simple red dot. A 300 aac isn't a practical or ethical hunting round much beyond 150 yards for my purposes so the red dot is perfect. That said, it is a 300 yard shooter with that scope (further I'm sure, but our range is only 300). Great PSA product.

Great upper
I paid $300 for this upper before the election. It had a couple of scratches on it from handling. It obviously had been attached to a lower and test fired as it should be. This thing is accurate. I have fired 147gr FMJ and the Sig 120gr solid coppers out of it. At 100yds it was hitting 1/2" to the right. Turned the turret two clicks left and we are hitting bulls.

Good upper good price
Bought this upper 2016 cyber Monday sale took couple weeks to get here but worth the wait. Shoot perfect out of the box I have over 60 rounds down it Remington 120 gr and ate them with no problem at all. After a short break in was shooting under 1" at 50-75 yrs. Gonna get to a longer range and see how it does at 100 yds plus.
