Does this barrel have 5R rifling?
Henry M on Aug 19, 2018
Which lower do I need to complete this build?
SharpKnife on Aug 14, 2018
BEST ANSWER: Any Ar15 lower would be fine. You'll just need the correct magazine to insure proper function.
Why do the people answering the questions get upset? Is there something on your sight that prevents data entry mistakes? If you want to have people answer questions that’s fine but they shouldn’t be giving anyone a hard time.
Matthew M on Aug 17, 2018
Is this a type 1 or type 2 6.5 Grendel bolt/barrel combination?
Zach S on Aug 16, 2018
BEST ANSWER: Chamber description above says type 2.
Is the bolt different from an AR 15 bolt and bolt carrier? And I have a regular PSA lower this upper is all i need to shoo 6.5 grendel?
Manuel L on Aug 16, 2018
BEST ANSWER: Yes, the bolt face is the same as the Russian 7.62x39 - not the 5.56 or .223. This upper with its bolt carrier group is all you need, if you have an AR15 lower. Also, you can't just interchange bolts even between same caliber AR15's . For safety they should be head space checked before use.
Does this come with a matching bolt?
Kyle A on Aug 15, 2018
BEST ANSWER: From the description:
Bolt Carrier Group Included: Yes
I have a dpms Oracle chambered in 5.56. Will this upper fit on the lower i already have?
Chris on Nov 7, 2018
BEST ANSWER: This upper will install on any standard AR-15 lower. You will want to purchase different magazines to work with the new caliber though. Mine fit perfectly on a 5.56 lower.
What's the difference between this upper,and the other 6.5 Grendel upper #8709?
Charles J on Nov 10, 2018
BEST ANSWER: Through my research I could not find a difference between SKU# XXXXXX9156 and the SKU# XXXXXX8709 other than the handguard is of a different design. My decision was based on two factors.
1. I prefer the more skeletonized design without the continuous Pictiny rail on top.
2. At the time of my purchase the one ending in 9156 was at a lower price.

What is the difference between this upper,and the other 6.5 Grendel upper #8709?
Charles J on Nov 10, 2018
BEST ANSWER: There is not enough information in the descriptions to provide what, if any, are the differences between the the two uppers. When I ordered mine, only one was available. Based on the current identical descriptions, they seem to be the same. The manufacturing numbers are different but they do not say who made them.
Grendel or Creedmor. What's the difference?
Joseph on Sep 2, 2018
BEST ANSWER: They are not interchangeable. Grendel is based on the 7.62x39 and the Creedmore is based on the 7.62x51 nato.
What magizine should you use with this caliber ?

psa 20" 6.5 grendel upper

Get one.
I can't say anything negative about psa service or their products since I've been buying from them the last two years. The 6.5 upper runs flawless out of the box with just a shot of oil. It shots factory loaded 120gr federal fusions into 2 inch groups at 200yds. The factory 123gr hornady black eld match will do 3 inches at 200yds. Not bad for not cleaning or breaking in. Thats straight outta the box. U can't go wrong for the price. All three of the 10rd c product mags work great.

great value
consistently gives sub moa groups. I would give it 4 stars but, adjusting the gas block requires removing the handguard. annoying.

Can’t go wrong
Perfect for the price, great quality, fit very will with my Anderson Lower, put a crossfire scope on it, took it to the range and 5 rounds to zero in and sub MOA, going to be a great hunting rifle this season.
