Does this come assembled?
Keith on Feb 15, 2019
BEST ANSWER: The upper will be assembled. The lower can't be assembled without a receiver. It's easy and fun to do. There are many complete assembly videos on youtube.
5.56 can be used without issue?
J G on Feb 15, 2019
BEST ANSWER: Yes, a Wylde barrel can shoot both .223 and 5.56
Sure this is an 1:7 twist barrel and not an 1:8 twist?
David M on Feb 19, 2019
BEST ANSWER: I'm pretty sure they know what twist rate they build... but you could buy it and do the measurement. Mine is awesome at 500 yds with 62 gr. 556...
Will there be any issues shipping this to NY?
Victor S on Feb 18, 2019
BEST ANSWER: They can ship it to NY.
Can it be shipped to California ?
STEVE G on Feb 28, 2019
BEST ANSWER: Yes,I bought one, you'll get more than you pay for.its the best deal I've see on psa so far and I've bought 3 different rifles from them so far.
Am I correct in assuming this only needs a stripped lower receiver to be complete?
Christopher T on Feb 16, 2019
BEST ANSWER: A lower. The tools and the time.
Can you shoot 5.56 out of this set up?
Kelley G T on Apr 15, 2019
BEST ANSWER: Yes, the .223 Wylde is designed handle 5.56 and .223. It is supposed to be more accurate with the Wylde chamber. It has ran great for me.
Does this upper have a qd sling port on the mlok rail?
randy l on Feb 28, 2019
BEST ANSWER: Yes, it had two - one on each side of the hand rail, just in front of the received/barrel nut.
Could you use this to convert your ks-47 to 223?
mike T on Mar 25, 2019
BEST ANSWER: Not possible. The KS-47 uses a completely different lower and FCG than does the AR-15 lower.
Can this rifle kit be shipped to a PO Box in Idaho?
Mark B on Feb 18, 2019
BEST ANSWER: Palmetto State Armory doesn't ship to PO boxes.
Is this considered a heavy barrel that could be shipped to Maryland?
Kenneth J on Feb 28, 2019
Whats the difference between this upper and the upper with sku# ending in 448754? Obviously besides this coming with lower parts.

Great Rifle, made a few modifications.
I bought this upper and put it on an aero precision lower, changed the bolt carrier group, and put on a red dot sight, an angled fore grip and a new muzzle break. it operates perfectly.

Fantastic rifle kit - extremely well built, and you can't beat the price!
My first impressions of the rifle kit and especially the upper build were good. Really good... I honestly couldn't believe how well-built this rifle kit was when I received it, and I can't understand how PSA can build something of this quality at the price they charge. It really is a remarkable achievement in the retail firearms sales world.

Now, first off, I could have built this rifle kit and left it bone stock - as it was configured in the kit at the factory, just add my preferred lower receiver, install the lower parts kit, and it would be a great rifle, a solid performer you can bet your life on. Or, you can do something like what I did, instead...

Building this kit has made me a life-long believer and customer for Palmetto State Armory and their rifle uppers, lowers, and complete kits. Building this 18" .223 Wylde rifle kit has stoked the fire in my belly to make me want to build more and more of these rifles to fill various needs and niches - everything from a CQB SBR/AR Pistol to a 16" everyday patrol rifle with particular upgrades (optic/trigger/grip), to an AR-10 for deer and hog hunting.

For this rifle build, I mated my upper and lower parts kit to what is, in my opinion, the best AR-15 lower you can get without spending a small fortune on some custom billet lower - I chose the Aero Precision M4E1 lower. It's quality is apparent at first glance - threaded bolt release slot, which removes the requirement of pounding roll pins in places you don't want to use a hammer. Much easier to just use a small Allen wrench with some blue loctite.

I then replaced the A2 flash hider that came in the kit with the Aero Precision VG6 Epsilon 556 muzzle brake. It's one of the three best muzzle brakes on the market for the 5.56 AR-15, and in my opinion, it IS the best of the three available.

My next upgrade was to replace the stock plastic magazine release button with the Odin Works custom extended and skeletonized aircraft-grade aluminum magazine release button, and next it was the Troy Industries extended Bolt release lever - better than Magpul's BAD Lever and costs about 1/3 less - and the standard safety selector switch was replaced with the Trinity Force AR-enhanced ambidextrous safety selector switch. The anti-walk trigger group pins were also from Trinity Force, and are constructed of Melonite-treated stainless steel, so they're built tough with a finish that will withstand all the abuse a safety selector takes over the life of a rifle.

Next, I replaced the always functional and well-made Magpul MOE stock that was part of the rifle kit with the Mission First Tactical Battle Link Minimalist stock. Aside from the LaRue Tactical MBT-2S-SB trigger upgrade I installed recently, this stock replacement was the best upgrade I made to the rifle for length-of-pull and comfort. The cheek rest is more substantial than on the Magpul MOE stock, and it doesn't move on the buffer extension nearly as much as the MOE, giving solid lockup at every position.

Of course, the Magpul MBUS sights are something that every rifle needs - a good pair of iron backup sights - well, in this case, polymer - are a must-have for any build. They're great backup to my chosen red dot optic to mount on this particular rifle build - the Vortex Strikefire II red/green dot 1x optic. It's a real workhorse of a red dot, holding true through serious training, sustaining drops, bumps, and bruises and keeping true to its point of aim/impact. I have no complaints.

All in all, this was an extremely enjoyable build. If you're just wanting to run with it as the kit comes, that's perfectly fine! All you need is the lower, some basic tools, about an hour (or less) of your time, and you'll be off to the range to zero it in no time flat. It's accurate as you want it to be. The range in my area only goes out to 300 yards, and at that distance with the Vortex Strikefire II, I've been able to get consistent groups with standard 55 gr ball ammo at 1.5 - 2 MOA, which ain't bad. When I kick it up a notch with better ammunition (62 gr. Nosler "Varmageddon" ammo in .223 Remington) the groups tighten up to just about 1 - 1.25 MOA, which is impressive, considering I don't own a lead sled - just a range table and my range bag to rest the rifle on...

So, should you buy this rifle kit? Oh, hell yes! You simply can't go wrong, you can't screw it up, and it's more accurate than you're capable of being, so it should serve you well in whatever capacity you wish to use it. My hat is off to Palmetto State Armory for building such high quality rifle kits and components at reasonable, affordable prices.
I started out with the EPT trigger, which was better than your mil-spec triggers.
I installed the LaRue Tactical trigger, and man, what a difference! From 5.5 lbs down to 2.5 lbs.
Important to install anti-walk trigger pins on a custom trigger. Keeps things nice and stationary.
This is the completed rifle before the final upgrade - the LaRue Tactical trigger. Best upgrade!
This rifle kit was fantastic. I replaced the EPT trigger, the flash hider, and the stock.

Very nice upper and quick shipping too. Product shipped on Monday and received the package the following Monday in southern California. Came with all parts needed to complete rifle except lower receiver. No missing parts. This is my first build and i love this upper. Very well packaged with foam inside of the box. Sights were easy to put on. BCG is oiled up. There were a few very minor scratches on the handguard but they're really not noticeable unless you're going out of the way to really look for them. Has ".223 Wylde " engraved on the barrel. Psa logo under the handguard. Super clean looking upper. .223 Wylde with M-lok is the way to go. Giving this item 5 stars even though it hasn't been shot through. I will leave another review and rating once I take it to the range.

Great Value
I got this kit for Christmas and built it on an Aero Precision lower that i got from my local store. the kit went together pretty easily considering that I'd never built an AR before and had only basic tools. I added a red dot and took it to the range with a variety of .223 and 5.56 ammo and only had 1 or 2 user-induced issues. I have not tested any steel cased ammo in it yet, but am very happy with how it shoots. The reason i didn't give 5 stars is that i haven't had a chance to shoot it outdoors past 50 yards, so I don't know exactly how accurate it is at distance. I think this was a great value for anyone who doesn't mind spending just a little time to build it.

New Build
I just put this together on an Anderson lower, so far I love it! I shot 20 rounds out of it freehand at 50 yards with the Magpul sights and had about a 3 inch group. I am happy with that group so far as I wear bifocals and the group is me, not the gun. It looks beautiful, fit and finish is very nice. The recoil is very soft due to the rifle length gas tube. The only reason it doesn't have a 5 star rating (yet) is because I want to shoot it thru a sled and see how accurate the 1/7 barrel is.
