Great upper for the price.
Had it short stroke a lot.
Took it apart to find the gas hole was slightly small. Opened it up a tad and now it runs flawless.

An excellent upper so here's why 4 and not 5:
1. Dear Moriarti Armaments! You should've been able to figure out ahead of time that a properly installed scope with standard eye relief (say, 3-4") will render a standard CH useless. I mean, this is basically a long-range barrel. People will install large scopes on it. Should've at least given me an option of something like raptor. No biggie. I bought a Raptor CH. Works like a charm.
2. A few times, the bolt failed to stop in the rear position when the mag was empty. Still trying to figure out if it's related to the mag.

Otherwise, a truly excellent upper. The barrel is amazing. I was testing it yesterday at 500 yards and it did just as good as a 24" barrel bolt action in 6.5 Crd. Excellent work. Thank you! Will buy from you again.

I received the package.

Thank you again for the outstanding customer service and support.

I have recommended you to a couple other Marine friends who are looking to make purchases this year.

Thank you again and look forward to giving more of my business in the future.
