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.

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.
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.
Does this come with a matching bolt?
Kyle A on Aug 15, 2018
BEST ANSWER: From the description:
Bolt Carrier Group Included: Yes
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.

Shoots great! 1/2 MOA with Hornady Black 123 gr. Functions flawlessly, just slapped it on my Lower and sighted it in. Can’t beat the quality and price!

Very impressed
Shipping was fast, took it out of the box and mated it to a bci lower I put together with a pof trigger. Used a couple E-Lander mags, shoots like a dream. Cycles everything I’ve fed it so far , and am shooting sub MOA groups at 100 yards. Couldn’t be happier!
6 shot group
Top one

Nothing but impressed
Nothing but impressed. Shot half inch groups right from the start. Great quality at an unbelievable price.
September 15, 2018
Nicely done.
Well built, but not the accuracy I was expecting. Cycled beautifully, hoping a little more break-in will help.

6.5 grendel
Been drooling over 6.5 for 2 months. had one picked out from another co. psa ran this one on sale, lucky me. Shipped quick. Looked great. Disassembled cleaned, mounted 6 to 20 simmons, bore sighted the old way. first shot at 25 - 2 in low tried at 100,2 in high 1in to left 2nd shot out of the barrel! cleaned every other shot. Shot 10 more still cleaning. Not good. This barrel likes to be fouled. Went home cleaned it. next day still at 100. fired fouling shot no. 13 4in high-next 4 measured 1.87-next 3 measured 1.45 all in the black. Hornady black 123gr. I'm real happy.

A happy old vet.
Just ordered it last night, can’t wait to look it over. If it’s as nice as the 224 Valkyrie that I received from palmetto this will be a very happy old vet wish we had these back in the 60s. Thanks palmetto armory you all are the Greatest.
