Does this barrel have 5R rifling?
Henry M on Aug 19, 2018
what barrel blank is used and who finished its machine work and chambering?
Larry G on Sep 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.

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.

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.
this a heavy barrel?
Brian g on Dec 9, 2018
BEST ANSWER: No. Its an A2 profile which is heavier than necessary from the gas port to the muzzle. It isn’t a heavy bull barrel though. I think the upper weighed 4lb 8oz.
Does it come with the barrel nut wrench to swap handguards?
geoffrey n on Nov 16, 2018
BEST ANSWER: No it did not. I really like the handguard on this upper really light.
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.
What magizine should you use with this caliber ?
Jay on Aug 19, 2018
BEST ANSWER: I second the E Lander. No issues at all. I have the 17 round mags.
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.

Mediocre at Best
Fit and finish is nice however accuracy is lacking. I haven't quite found a load this rifle likes yet and it wont cycle any hand loads for whatever reason, only factory Hornady custom loads. I've only been able to achieve ~2.5 MOA at best so far.

Great upper.
Great upper no problems whatsoever. Took 2 Whitetails this 2018 season using Hornady black. Fit right on my Dpms lower like a glove. Didn't need to adjust the gas block at all. I highly recommend.

Well Built
Overall fit and finish is well done, working up loads now but so far it is grouping pretty tight.

6.5 Grendel build price yet we'll see how the quality holds up......thank you P.S.A.
Been looking at 308,6.5 Creedmore and others have young shooters interested in accuracy and distance so went with the Grendel for a softer pop and yet will take a white tail too we're still in process of building it to our liking so far ......... price was best of all quality was very nice as well ...but the assembly was a little rough and I mean a little but the stainless barrel had a drag mark on it from the install of the hand guard their again price was half of the others can't wait to see how it shoots turning out to be a bmfr ....once again thank you for the price point ... ready to send them down range

Awesome 6.5 Hog Rifle
I have had this 6.5 Grendel upper for about 2 weeks and I love it. No more recoil than .223. It is lightweight and very good quality. I put it on my PSA lower with Elftmann 3.5 pound trigger. Very accurate and so far no jams or misfires. I used Hornady Black 120 grain ammo to break in the barrel. So far I have shot 1 box of Hornady Black 120 grain and 2 boxes of Federal Fusion MSR 120 grain PSP bullets thru it and it seems to like each.
And it is a real Hog killer. I have taken down 14 in 3 nights with some over 200 yards. Can't wait to get it back out there.
I highly recommend this upper if you don't have one already.
Ammo is a little pricey, but I plan to reload.
