Many people know about Palmetto State Armory, or PSA for short as a new player in the AR world. Specializing in online sales, with store-fronts in only South Carolina, they have been flooding the market with low priced uppers and lowers for the past few years. They follow the mold of many other companies in that they don't manufacture any of their own parts, preferring instead to outsource and assemble them into uppers and lowers. To many, including myself, they are the TJ Maxx of the AR world, with a rotating stock of goods that changes by the month. For their AR uppers, they focus on providing a high quality barrel and a high quality BCG for one of the lowest prices around. I personally am a big fan, as most other parts of an upper are generic and rarely fail or develop problems.

The barreled upper that I own is from their Premium line, which sports a FN-made chrome lined barrel that is button rifled (as opposed to hammer forged). Mine specifically is a 16" government profile mid-length barrel, 1:7 twist, made from CMV steel, and is HPT/MPI tested. It is phosphate finished and has a pinned F-marked FSB. Also included were a pair of single heat-shield handguards, which I have replaced with Magpul MOE handguards. The flat top upper receiver is forged 7075, has a T-marked rail and M4 feed ramps. When they are in stock they sell for between $260-280 (as of 2013-2015 time frame) and may or may not come with a BCG, charging handle or rear sight. I bought mine for $280 (without the BCG/CH/Sight) plus $15 shipping. The lower is a PSA blem. I have replaced the 6061 buffer tube with one that is 7075. I'm also using a B5 grip and a BlackHawk buttstock (which is made by Knoxx).

A big topic of conversation in the AR world is about how an upper is "gassed". That is to say, how much gas from the burned powder is being used to cycle the action. Over-gas the rifle and you are putting extra stress on the extractor and it can even lead to malfunctions. Under-gas the rifle and the bolt won't lock back on empty magazines or it might even start short stroking. In proper context, whether or not a AR in over/under gassed is relative to how much gas is being put through the system. A rifle that is fine shooting lower powered ammo like steel cased of PMC Bronze might be over-gassed when shooting Independence 5.56. The opposite is also true. In my experience, PSA's 16" mid-length upper will run anything from steel cased 223 to full power 5.56 without malfunction, but it is over-gassed at the high end with a basic carbine buffer and spring. I also tried an H2 buffer for a while, but didn't notice any real difference in perceived recoil or ejection pattern, which was slightly forward of 2 o'clock. Since I shoot reloads at about max pressure for 223 ammo, I have started using an extra powered Tubbs flatwire spring with the carbine buffer. I think it offers the best overall solution for full powered 223 and 5.56. If I were shooting steel cased Monarch/Wolf, I'd stick with the included buffer and spring. If I were shooting exclusively 5.56, I'd probably use the extra powered spring and H2 buffer. Ejection pattern isn't gospel, but I do prefer to have it in the 3-4 o'clock range.

So lets talk about accuracy for a moment, which is important but often over-rated. I think many shooters, especially new shooters, focus on things that are measurable but don't put them in the proper context. When looking at a firearm as customizable as an AR, one needs to think of it as a system. There is no point in focusing on one part and neglecting another, like buying a highly accurate barrel and shooting cheap, inaccurate ammo out of it, or shooting it without a support, or with a red dot/low powered optic. Any accuracy advantage gained is completely negated by one or more other factors. That is why I am a big fan of chrome lined barrels. They last a long, long time and are accurate enough for most peoples shooting styles and abilities. My PSA specifically is good for an AR, without being amazing. Using a sandbag for a support and my Weaver Super Slam 2-10x42mm scope for testing, I was consistently able to shoot at or around 1.5moa with ammo it liked. Using some cheap FMJBT bullets, the accuracy went down to about 3-5moa. These are all 5 round groups at 100 yards, with 55gr Hornady SP w/c, 52gr Hornady BTHP (both reloads) and 55gr HP Hornady Steel Match.



The bolt carrier group (BCG) is a premium PSA blem which has no markings on it. I bought this before the PSA upper and used it in my 20" A2 rifle for 2-3k rounds. It is approaching 9k rounds. The bolt is made from 158 Carpenter steel, has been MPI'ed and shot peened. It was not HPT, nor is it marked MPI on the bolt. It came with a standard extractor spring, black insert but no O-ring. The bolt carrier is 8620 steel with phosphate outside and chrome lined inside. The gas key is staked heavily, which is in favor right now because almost no one ever has to replace one. The only wear has been to the finish and some erosion on the carrier at the gas ports. I have replaced the extractor and insert with new one as part of preventative maintenance.




The charging handle is forged 7075 and has an extended steel latch. The cost came to $40 between the two items, which puts it in the same price range as the enhanced CHs like the BCM Gunfighter. I don't regret the purchase, but for the price of CH + aftermarket latch, there are other options out there. Extensive use of an extended latch will lead to uneven wear in the finish, as can be clearly seen.



The rear sight is PSA brand, but they are also included on some Sig ARs. This is the newer version (which has been around for at least 2 years) and are improved over the older ones, which had trouble clamping on the some rails. These do sit a bit low compared to other rear flip-up sights, which means most people with them will have to lower the front post quite a bit, but mine has no zeroing problems from it. It also comes with a large and small aperture, which is a perk on a budget rear sight.

The compensator is a BCM Gunfighter Mod 0, which I got for free on a 16" BCM upper I bought last year. The normal retail price is $80 for the comp. I know when I received the comp there was some literature about it showing excessive wear and losing effectiveness, and how that concern was over-rated. BCM advised that it could wear significantly and not suffer from it, but in my experience wear hasn't been an issue. This is more of an issue for people who want to use a 14.5" barrel with a pinned/welded muzzle device, as the muzzle device needs to last the life of the barrel. I personally have mixed feelings about the Gunfighter comp. The short answer is I think it's way overpriced for what it does. While it's still effective as a flash hider, and doesn't have nearly the side concussion of other muzzle devices on the market, it doesn't reduce felt recoil all that much either. I think of it as a modified A2 birdcage, at 10x the price. Now I got mine for free, but if I had to pay, I'd probably go with a Yankee Hill Comp, which isn't all that different, for 1/3rd the price. If I was going to spend closer to $100, I'd get the FCS556, which from my personal experience is head and shoulders above the Gunfighter in reducing felt recoil, at the cost of increased side concussion. In the end, there isn't a "free lunch" to be found between felt recoil and concussion to the shooters around you, but I don't think the Gunfighter offers enough of a difference compared to the A2 to be worth ten times the price. There was a semi-scientic study done which compared a variety of muzzle devices and how they effected recoil, in which the Gunfighter came in last among the hybrid type devices, reaffirming what I already suspected after shooting it myself. http://www.thetruthaboutguns.com/2014/11/jeremy-s/556-muzzle-device-shootout/



The MOE handguards are good and are one of the best ways to attach items to the rifle for cheap. The only down side that I can think of is the way the heat shield is attached. Because it is held on by a metal screw that is exposed on the outside, heat can transfer directly from the heat shield and to my hand. When shooting multiple magazine in a row, or less in the summer, the front of the guard gets uncomfortably hot. It isn't a deal-breaker, but is still something to be aware of.



Overall I have a little less than $1000 invested in the rifle, which is including the Aimpoint PRO. The think the strong points of this setup are;
- Very fast shooting at close ranges
- It can shoot respectable groups at 100 yards and hit torso size targets at 300 yards.
- Everything on the rifle will last a very long time and isn't sensitive to bumps or scrapes.
- The rifle will shoot all the 223/5.56 ammo I have tried with it, and is adjustable to be better suited with higher pressure 5.56.
- Reliability has been great. I know lots of non-AR people on the outside looking in think that ARs are finicky. The truth is the system does take some maintenance and knowledge to get the most out of it, but those needs are greatly over exaggerated. The biggest thing is don't shoot your rifle bone dry if you don't want problems.
- I could of spent more money and not gotten more out of the rifle. For the AR, shooting skill is much more important than high end components, outside of dedicated competition based equipment.

I think in conclusion I think that PSA barreled uppers are a great value and when looked at from the perspective of "guns shoot bullets", there isn't anything separating it from higher priced options. The same can be said for PSA BCGs. Reliability has been flawless with the exception of some bolt over base jams with an E-lander magazine that I eventually threw away. PSA lowers do have 6061 buffer tubes, which is a deviation from some of the higher priced lowers available, but I replaced mine with a 7075 one for all of $40, so it is an easy upgrade for those who think it is important.

I think PSA should appeal to people who are looking to get a quality rifle with basic features. They certainly don't offer the variety that other brands offer in terms of rails, but those can really drive up the price with sometimes questionable gains. They also don't have the resale value of other brands, but cost less to begin with. Generally speaking, the true cost to own a PSA rifle, with everything that a person needs to shoot it minus ammo, is around $600-800. If you are looking at buying an AR, or PSA specifically, my advice is not to spend your entire budget on the gun itself. Sights, optics, magazines, a sling, and maybe a light will all add cost to the rifle. You'll be better off factoring in those costs as well. The good thing about a PSA Premium (or CHF) upper, along with a PSA lower, is that they aren't starter guns which will need to be replaced after a few years.

Good write up. I've 2 PSA 16" carbine builds and plan on adding either a 16" middy or the new 18" middy down the road.

My one is approaching 2000 rounds no major hang-ups, and I've been running nTula through it the last 1000 rounds just to see what happens

That is a most excellent review with great details! As the owner of several AR's, one of which is a PSA Premium carbine gassed upper I agree wholeheartedly with your closing statement. For a quality budget AR, the FN barreled PSA Premium or CHF uppers are very hard to beat! $1,000 including a quality optic like your Aimpoint PRO ($370.00 shipped is the best price I've ever seen which was PSA Black Friday by the way) is a very good deal!

Their Premium line features a FN made, chrome lined barrel that is button rifled instead of CHF. They usually sell for a bit less than the CHF models. I personally don't think there is enough evidence saying that CHF is better than button rifled in a Semi-auto, so I saved $20-30 and went with the Premium. If the barrel is made by FN is will say, also if the barrel is CHF it will say. If it doesn't, then it isn't.

PSA also offers the Freedom series, which can include a nitride barrel, stainless barrel or an unlined CMV barrel. PSA will also occasionally sell a chrome lined barrel that isn't made by FN too, usually for a bit less than the Premium line.

My thoughts are this; if you plan on owning the rifle for a long time, get the Premium or CHF. If you don't plan on shooting the rifle all that much, there is nothing wrong with saving some money and getting one of the cheaper Freedom rifles. Really the only thing different about them is the barrels. I own a Freedom upper myself and it is great, but I'm using it as a loner rifle for when I shoot with friends. Maybe when ARs are 100% obsolete and we are all shooting the next greatest thing, it will have 2k rounds through it.
