Do you ever get tired of silly questions that could be answered by reading the description?
Smart guy on Sep 20, 2018
BEST ANSWER: Sure do!
This does come with a complete lower parts kit correct? All it needs is a striped lower?
Chris B on Aug 16, 2018
BEST ANSWER: That is correct.
Will this set up work with subsonic ammunition?
Tater Salad on Aug 19, 2018
BEST ANSWER: Technically yes. It will fire subsonic ammo. The 1 in 7 stabilizes subsonic 200gr plus projectiles better but this will work if you aren't worried about moa accuracy at any sort of distance.
Will any stripped AR-15 lower, like the PSA AR-15 1728 lower, work with this kit?
Wayne W on Aug 17, 2018
BEST ANSWER: Any AR lower will work. Lowers are NOT designated pistol or rifle. They just say multi caliber.

Can you attach this kit to a standard AR-15 Lower unit?
TheWilk on Mar 19, 2019
BEST ANSWER: Unknown, I purchased a PSA lower. For all intents and purposes I would assume it would.
Can you change the handguard on this upper if you want to?
Patti on Oct 8, 2018
BEST ANSWER: Yes, you can change out the handguard with any free-float handguard designed for the AR platform. This barrel configuration will not accept standard M4-style handguards.
Does this come with the complete upper?
Summer D on Oct 4, 2018
BEST ANSWER: Yes, everything you need except for the lower receiver is included.
I'm wanting to buy an upper in 300 AAC Blackout.
My question is, which is better for all around use, subsonic and supersonic rounds, the pistol upper or rifle upper??? Thanks
Frank S on Sep 30, 2018
BEST ANSWER: If you are using a suppressor subsonic, if not you won't see enough of a difference for it to matter
What is the overall length when completed?
Eli M on Apr 5, 2019

Great value at any price
Got this on sale and put it on an Aero Precision lower. Fit perfectly. All parts went in like butter and function smoothly. The machining is top notch, all parts nice and clean. The completed pistol feels substantial and good in the hand. The furniture is Magpul and really nice. FOR ANY PRICE, PSA deserves a second look from anyone wanting quality parts. Pay for a fancy name and for bragging rights. Or pay for what you want: a good looking, well-made, reliable firearm. PSA has a fanboy. They deserve it.

Great looking upper
Shipping was fast and I was glad it had an extra set of springs and detent pins. After completing the build, it shot good and looks amazing!

1st Blackout on the wall.
The 300 Blackout pistol kit, in the words of Tony the tiger
"Its gerreeaat!" There are things that really surprised me about this build. Even thought its such a large projectile and short barrel there is less recoil than a normal rifle length 556, seems even less recoil than my 9mm sig. Target acquisition is almost instant after each pull of the trigger. The only draw back is the price of ammo and accuracy beyond 75+ yards. I will eventually try out a rifle length barrel and gas system for the blackout but as far as this 300 build kit goes, if you don't already have one and have the money for a new addition to you AR family order it today! If you do have one well then......buy another you know its worth it!

Highly recommend
The upper looks awesome, hand guard is finished nicely, and most importantly it goes bang every time. Highly recommend.
The ONLY negative is slow processing and shipping times.

It was okay
Considering I’ve purchased several of your items this is the first problem I’ve ever come across. When assembling the lower, the safety selector switch it had massive burrs in it hindering it from going from safe to fire. It would continue to get stuck. I wasn’t about to hammer out the roll pins for a return so I ended up buying another LPK for other projects and to replace what I needed. What a hassle.

Great kit, exactly what i wanted to build only complaint is that the first range session i used it on the rail came loose, havent had it out sense so will keep a lookout on that to see if it continues and only other minor thing and this is all me because i wanted the 8.5" with the 7" rail but when i put my bcm hand stop on it the gas block was in the way

Very easy build.
I can’t believe how easy it was to build.
My 300 blackout pistol. I colored the magazine pink so I don’t load it into a 5.56.
I haven’t shot it yet but I can’t wait to. I’ll be sighting it in in a couple of weeks.
