What kind of blower would I need for this pistol kit?
Eric S on Oct 2, 2018
BEST ANSWER: I prefer female, but you be you.
How many inches is the barrel from when the gas block ends?
Marco F on Feb 2, 2019
What kind of lower would I need for this kit?
Eric S on Oct 2, 2018
BEST ANSWER: Any new lower that says "multi-cal" or some such. If a lower is assembled as a rifle first, it is always a rifle in the eyes of the law, so start as a pistol. Otherwise, the ATF will talk to you about your unregistered SBR.
Will this fit a pa10 lower?
Garrett H on Oct 9, 2018
BEST ANSWER: To my knowledge - no. These are designed for AR-15 lower. The 6.5 creedmore is designed for the AR-10 lower.
Is this type 2 bolt?
Roger B on Nov 2, 2018
BEST ANSWER: Yes. I have one and love it.
Is this a 300 blackout? Or chambered to .556/.223
Davidg on Dec 20, 2018
BEST ANSWER: Is this a joke?.....this has to be a joke!
The “full auto” BCG included with this, is that the standard style? Not wanting to purchase a full auto kit.
Chris L on Feb 27, 2019
BEST ANSWER: The BCG full auto designation is really only an inference to the style of cut outs and dimensions of the BCG. The bolt carrier would be compatible with an automatic capable lower receiver. It is NOT however inherently automatic. This is very common, though there are semi-automatic only BCG's out there as well.
Does this kit come with a 6.5 Grendel specific buffer tube plunger and spring or is it rated for 5.56/2.23?
colton s on Apr 9, 2019
BEST ANSWER: An AR will run without the buffer retainer plunger, just have to pop both pins instead of break/tilt off the front pin. In other words, I don't see how it would even matter.
If you're talking about the actual recoil buffer/spring, that doesn't matter either, it's absorbing the recoil from the gas port/bcg, not a larger cartridge, so that doesn't matter either.
You may have to play with buffer weights for reliability, but that's an entirely different matter.
OK so a lower , bought solo, can be fitted to a pistol upper, and be a legal pistol?
Thomas C on Nov 22, 2018
BEST ANSWER: My class 111 FFL contact stats that when you buy a stripped lower it has never been designated as a pistol or a rifle and can be built by the buyer and designated to be what ever he builds.
Does the handguard on this upper use a non indexing barrel nut?
CLINTON on Oct 10, 2018
BEST ANSWER: Yes, you can tell by the bottom of the hand guard where it meets the upper receiver. The bottom of the hand guard is pronounced and two bolts run through it to clamp the hand guard to the barrel nut.
What weight buffer is typically used for 6.5 grendel. Info says standard ?
Forrest S on Feb 10, 2019
Anyone have tips on a lite weight build? My son has a 10” 300 blackout 7lbs.

Fantastic buy for the money.
I’m in love with this upper. Easily kept 2moa 5 shot groups with 100 grain wolf!! The Hornady 123 ELD shoots right at 1 MOA

The hand guard was loose and slid forward after 5 shots. I torqued the screw and ran 100 more without issue.

Great pistol (rifle)... Kicks like a mule.
Great quality pistol (rifle). I will be putting on a muzzle brake to help reduce felt recoil.

Man this rocks. Great truck “pistol”. Solid package. Mates up well with Anderson lower. No complaints. I can hit soda cans at 200 meters with a 4x optic.

Definitely has a "cool" factor.
What a blast. Has yet to malfunction and is plenty accurate. Have killed a doe and several nice boars with this gun. Absolutely no complaints.

6.5 Grendel 12” Nitride pistol
Really like this pistol, shoots good. I added a tactical latch, swapped out EPT for a 2 stage trigger, 1-6 optic, quick disconnect sling swivels and Blackhawk sling. Makes a very handy package. Pistol has functioned 100%. I wouldn’t hesitate buying another one. The 6.5 Grendel cartridge is very versatile, even out of a 12” barrel.

Can’t wait for them to be on sale again
I like the pistol kit it is a perfect balance for Ga hunting. The 12” barrel handles /points great . Combined with Hornady’s Sst ammunition it was lights out for the hogs.

Don't like adjustable gas block, otherwise OK
I found the adjustable gas block to be useless and would prefer the increased reliability of a standard type. The arm brace seems very fragile to me but I do like that it uses a standard carbine receiver extension tube. Other than that, I found the kit acceptable for my purposes to make a modern PDW that doesn't need special licensing. One thing to note is that 7.62x39 magazines work just fine if you don't have any specifically for 6.5 Grendel. Also, Wolf 6.5 Grendel ammo worked flawlessly and is cheap compared to other calibers
