How well does this barrel hold up compared to a chrome lined one?
grant g on Mar 11, 2019
BEST ANSWER: Having owned both I would say Nitrite is superior in every aspect. Because chrome lined barrels add material to the barrel, Nitride is often more accurate. Nitride is better at corrosion resistance. Nitride also hardens the barrel. Instead of having a soft nickel inside, its a harder nitride chemical treatment. Chrome lined barrels is good marketing.
What is the difference between M-Lok Classic, M-lok MOE EPT, and M-Lok MOE+ EPT?

BEST ANSWER: "MOE" stands for Magpul Original Equipment which describes the style of hand guard and rails that make up the rifles accessory platforms. "M-Lok" describes the shape of the slots for attachments. "EPT" stands for Enhanced Polished Trigger which defines that the trigger will be smoother and maybe will reduce trigger pull pressure due to the fact it has polished parts that reduce friction. So, with all this said, I picked the M-Lok MOE style and only purchase accessories that are compatible with this platform on all my ARs so that I can swap things around. I hope this helps.
What’s not included? Will I need just a stripped lower?

Is the bolt carrier group phosphate or nitride coated and HPT/MPI?
Stephen D on Feb 16, 2019
Does this include the parts to fire it on full auto?
Victor G on May 22, 2019
BEST ANSWER: No it does not, since it is illegal to have a full auto weapon unless you have a SOT license with FFL or a pre 1986 registered machine gun.
Will this shoot .223?
Budda on May 23, 2019
BEST ANSWER: Yes. Everything barreled for 5.56 will shoot .223 just fine. Just make sure you don’t try to shoot 5.56 out of something that says it’s barreled for .223 because the pressure is much higher.
Can you add rail sections? Like 9 slot? Or more
Jr R on Apr 15, 2019
BEST ANSWER: Room for 19-21 slots on top. The bottom and sides are wide open for 28 or more slots. This handguard is 15" over a 16" barrel. Lots of room for slots and add-ons.
What do I need to complete this kit? Is the upper built? Will I only need to buy a lower to finish the build ?
Ummer on Feb 17, 2019
BEST ANSWER: You need a bare lower and tools nothing else.
Is this a mil-spec buffer tube?
AWSboys on Jan 16, 2019
BEST ANSWER: Yes
DOES THE UPPER RECEIVER HAVE THE FORWARD ASSIST?
Jeffrey P on Apr 3, 2019

Rusty on Mar 25, 2019
BEST ANSWER: No
Is this build NJ legal?
Christopher L on Feb 28, 2019
BEST ANSWER: Check your local NJ gun regulations/laws.
Is it possible to fit a mil-spec carbine stock on this mil-spec mid length buffer tube?
Loki- on Feb 13, 2019
BEST ANSWER: Mid-length refers to the gas system not the buffer tube.
Do you pinned and weld the muzzle?
Saroeun Y on Jan 25, 2019
BEST ANSWER: I would say they don’t. Companies only do that with 14.5 inch barrels to make the barrel a “permanent” 16 inches.
Can this ship to residence. Or does it have to be shipped to an FFL?
Fred P on Apr 4, 2019

Joshua H on Mar 9, 2019

Caleb T on Feb 10, 2019

After 100 rounds handgurard is coming off so pissed!!
Took forever to get but I realized that they are also building everyone’s upper at the same time. I got the rifle beautiful fit and finish looked good. Went to the range shot 100 rounds and when I was putting it back in the case I noticed my for grip was separating from my rifle extremely upset

My First AR build
As the title says, this is my first AR build. I was a little nervous putting it together, but with patients, a book on how to do it and more than a few trips to YouTube it was an enjoyable time. I ordered the lower a few weeks before the kit so I could paint it. I'm not much of a painter on that small of a scale but with some #9 solvent no one will ever see those mistakes. I'm looking forward to me next range day. THANKS PSA!! BTW whoever had the bright idea to include and extra spring, You also have my thanks.
The cleaned up paint job
All done.  Optics on.

Review Question
Looks like a great kit. Altho does this forend allow picatinny rails for assessories to be attached on top bottom and both sides?
March 18, 2019
Great quality and price!
This was my very first AR build, I paired this kit with an Anderson® Stripped AR-15 A3 Lower. I was surprised how easily assembly went without having a vise block. Everything functions as it should. The finish was blemish free, everything was well oiled and perfectly fitted. No loose hardware that I could find. It has ran each round perfectly so far. Palmetto State Armory didn’t disappoint! I will definitely recommend them to anyone interested in building or purchasing an AR.
PSA quality!

Good 16" Build
This was the second PSA build after the 10.5" pistol with the same handguard. The pistol came out great the accuracy is way better than expected and this 16" did not disappoint either. The groups at 50 yards are about 3/4" which is pretty good for my old eyes and a red dot. I just purchased and finished my third and hopefully my final one for while with the same handguard on the 18" WYLDE barrel. I have had very good luck with the PSA kits are extremely accurate for a price.. Very happy with two so far have not shot the WYLDE yet.
