Where it says "weight 4.0 lbs" is that everything shown or just the upper? This is exactly what I want except I want A pencil Barrel. Any idea the weight difference between barrels?
Jethro N on May 2, 2018
BEST ANSWER: I want the very same - in today's age of 'lightweight' uppers, it should have a quality pencil barrel with a .625" gas block, not a .750" - which is obviously a thicker and heavier profile.
Is this kit the complete rifle kit? I don’t see a lower? Thanks
Jerry on May 6, 2018
BEST ANSWER: It contains everything but the lower.
Is it recommended to use 5.56mm or would I be better off using .223?
Eliwonders on May 14, 2018
BEST ANSWER: I run both in all my Palmettos, Tula 223 75gr and lots of greenies(556 mil surplus brass 62gr). They both work great.
What is the difference between this upper assembly and SKU: 516446780?
Robert B on Apr 29, 2018
BEST ANSWER: Look carefully at the two handguards. This one only has a short top rail section at each end while the other one has a full length top rail.
Is the BCG and bolt the “premium” or the PSA standard? I see the material on the bolt is 158 carpenter and some stuff is chromelined, but it isn’t clear which quality level this is.
B lee on Jun 6, 2018
BEST ANSWER: Its the PSA standard BCG and Bolt
Will this kit work with any lower? That's designed for 5.56 anyhow
Hooli on Jul 3, 2018
BEST ANSWER: As long as is is a standard AR15 or M4E1 platform yes it should.
Is the low profile gas block compatible with the Strike Industries Strike Rail?
Nathan Y on Jun 23, 2018
BEST ANSWER: Yes it is
Do i need to purchase any tools or a toolset to assemble this rifle? Or is everything i need included?
Anonymous N on Jul 4, 2018
BEST ANSWER: It is possible to assemble one of these rifle kits with common tools, but it is recommended to have at least a pin punch set, nylon/brass hammer, and an armorer's wrench. If you want to go a little further, invest in a bench vise and receiver blocks.
I understand that this does not have the lower receiver, which is the serialized item, but does this still need to be sent to a FFL?
raptor jesus on May 31, 2018
BEST ANSWER: No FFL. This can be shipped right to your door.
Purchase one of your stripped lowers, and you have complete rifle, when put together?
Bryan G on May 14, 2018
BEST ANSWER: Correct. With the purchase of a stripped lower, this kit will contain everything else needed to complete a rifle build.
Is this the complete rifle kit? I don’t see a lower....thanks!!
Jerry on May 6, 2018
BEST ANSWER: No lower is included in the kit, which is why it can be shipped to your door. You provide a mil spec stripped lower receiver and a magazine.
Can anyone tell me which buffer weight this comes with? Thanks

Awesome Value
I'd recommend this package as it turned out great, shoots very well (no jamming), and looks great too. I don't know where else I could get such a high quality rifle for this price.

My first...but not my last
After being introduced to P.S.A. I looked for quite awhile before I purchased anything. I saw this kit and had to and I have absolutely no regrets! I enjoyed putting the lower together and was pleasantly surprised when everything locked up tight and sighted in better than any other rifle I have sighted in. Great quality and quick delivery.
