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.
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 this kit the complete rifle kit? I don’t see a lower? Thanks
Jerry on May 6, 2018
BEST ANSWER: It’s a complete upper with a lower kit. The lower receiver is separate
Is it recommended to use 5.56mm or would I be better off using .223?
Eliwonders on May 14, 2018
BEST ANSWER: I've run 300 rounds of factory and reman .223 in this AR with no issues. It cycles smoothly.
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.
Purchase one of your stripped lowers, and you have complete rifle, when put together?

Good value, but some work and parts required to get everything working.
I like the gun, and once I replaced the takedown pin, buffer tube detent spring, and buffer tube tetent, it ran nicely, and has since.

Very accurate with 69 gr ammo!
My third PSA build on Spike's lowers. This one is the same as the others; all are excellent quality, and very accurate with the proper weight ammo. This is a 1:7 twist, not 1:9. Using 62 gr minimum, accuracy is perfect for a 16" carbine. 69 gr Black Hills is ideal. Shoots around 2 minutes with a quality red dot, so that is as good as it gets with a light defensive rifle. 55 gr will work, but will not stabilize as well. As a result, not as accurate, no matter how you hand load them... This is not meant to be a match/ precision rifle, but a great, reliable carbine. Nice slim handguard. Very happy with PSA.

Kit contents great, accuracy is not good.
This was my first experience with PSA. Packaging and shipping were great. All components were new and well packaged individually. I know PSA very popular in the AR community and the package deals are great, but I guess you just have to decide what is most important to you. If it is accuracy, then these really might not be such a deal, because I a have pretty much decided mine needs a rebarrel or just sit in the safe and never come out. Basically this is a 3-4 MOA rifle which is fine for some folks but not for me. I have tried it with Fiocchi 55gr and my handloads which I have never found an AR that wouldn't shoot those accurately... but this one. But hey, it looks really good and that is enough for some folks.
