What is the overall length of this 12" pistol?
If it's over 26" is it still a pistol?
Kingkong D on Feb 18, 2019
Does this need a low shelf or high shelf lower to complete?
lawrence j on Sep 26, 2018
BEST ANSWER: Any Mill spec lower will work. Most lowers you buy will be high shelf anyways. Low shelfs come into play when your wanting to run (RDIAS) full auto sears.
What's the torque specification for the screws that clamp the handguard down?
Aaron B on Oct 11, 2018
BEST ANSWER: To be honest I torque until tight - it's clamp on so there are no torque specifications
Ar15 lower or ar10 lower?
Juice on Mar 13, 2019
BEST ANSWER: Ar15 lower, that's the beauty of the 6.5 grendel. Flatter shooting then a 308 but used a standard ar lower.
How does the shorter barrel affect ballistics does it have significant disadvantages?
alex b on Dec 27, 2018
BEST ANSWER: Theres a few difrent barrel lenth calculators out there I think when I looked it up it was still super sonic out to like 1000 with match ammo I used the American eagle otm for hunting this year and had a large deer at about 200yrds and it dropped it dead in its tracks perfect vital shot I aimed one inch high and I defently did not need to
I want a shorty gun like this but is it still good out to like 300 yds? I know its a trade of for velocity but i like the idea of a short 6.5 grendal
Marlan. K on Mar 8, 2019
BEST ANSWER: Yes, the round will be supersonic out to 900+ yards out of this barrel length. I do not think 300 yards would be a problem at all. Obviously, you will lose some velocity. Expect velocity at the muzzle to be between 2200-2300 depending on load. At 300 yards velocity will still be around 1800-1900 and 950 or so ft lbs.
Are the handguard on PSA uppers pinned down or can they easily be swapped out?
Rob C on Nov 1, 2018
BEST ANSWER: No there not pinned. There's two bolts you can loosen at the bottom and the handguard slides off.

Great buy!
Looking forward to deer season. Shoots very well after break in rounds. I'll be be putting one together for the old lady soon.
After break in. 100 yrds over the hood of the truck with the 6.5 grendel pistol.

6.5 grendel pistol
I own several ar pistols in .223 and 300 blackout. This 6.5 grendel pistol makes those obsolete.
I love this gun. Its the perfect size. I can't wait to get a 20" upper for long shots.

PSA 12inch 6.5 Grendel
I received my 6.5 Grendel pistol kit very promptly. once build i installed a primary arms 5x acog prism sight. First tim out i was shooting off a couple of sand bags. The 1moa center dit filled most of the center bullseye. once i got the rifle on target, i(never sighted in rifle with scope 2.75 inches above bore)i was good to go. i had several 3 shot groups at 1 inch and a few at 3/4 inch. i believe i might do slightly better, but im happy with just a 12 inch barrel. highly recommended. will try and send some photos.

Great Kit for a 6.5 Grendel pistol build.
This turned out rather nice for a pistol build and with the cerokote slick coating it has the smoothest out of the box triger pull. granted it is a letter sloppy on the initial pull. But the release is crisp and smooth.

Very nice
Absolutely amazing. Not quite as accurate as my rifle, but 1” groups are a piece of cake. The SBA3 almost negates to desire for a stamp.

Nice , machining is great, nice and lightweight. Made my daughters day by using it to take her first white tail.
