What’s the overall length of this?
Jim W on Jun 28, 2019
How is the accuracy on this being a 8.5 length barrel?
Sandoval247 on Jun 30, 2019
BEST ANSWER: I can't speak for this exact model but out of a 10.5" 300 aac PSA 1"8 barrel i had shot better groups (sub moa) than my 16". I currently shoot 1" groups out of a 7.5" barrel at 100 yards in 300 aac. Length isn't so much of a factor in accuracy other than being able to support the gun further out. It will diminish the power of the load compared to a longer barrel but that all depends on your load.
I have no problem dropping deer and hogs at 100 yards out of a 300 aac 7.5" barrel shooting 135gr sierra varminter bullets.
Description says 1/8 twist but title says 1/7. What is the actual barrel twist?
lronda on Jul 1, 2019
BEST ANSWER: I called into PSA, they stated that it was the 1/7 twist and not the 1/8 displayed in lower description.
Can this be purchased with a 10 round mag for state compliance?
Corey on Jun 30, 2019
BEST ANSWER: It uses the same .223/5.56 magazines as the regular so I'd say yes. The .300 round fits in the AR magazines. Having said that there can sometimes be some variances between magazine manufactures. I have read a few, very few, issues concerning the .300 and AR magazines.
Why does the header say “1/7 twist” when the body of the listing states several times it’s 1:8?
Scotty on Jul 30, 2019
Can I own this in North Carolina with a standard gun permit?
DONALD M on Jul 4, 2019
BEST ANSWER: Yes, this is a pistol. If you have a NC handgun permit or your CCW, you can purchase this.
Based on a previous response to the same question on the upper, I'm assuming the flash hider is just threaded onto the barrel and not pinned / welded - correct?
Andrew S on Jul 2, 2019
BEST ANSWER: I have that upper when I bought it seperate and it was just threaded.
Is this a 6 position stock and can I shoot 9mm with proper upper?

Very nice - great value
It has a loose fit but for $500 it is great. Ran about 45 rounds in first use and no issues - using SS 155 gr got less than 2" group at 100 yds.
