Add To:

Barrel: Barrel is made for Palmetto State Armory by FN Manufacturing using their proprietary blend of hammer-forged chrome-moly vanadium that is referred to as "Machine Gun Steel" by virtue of its use in FN's M249 and M240 weapons. The hammer forging process work hardens the steel, making it more durable. In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability. Chambered in 5.56 NATO, with a 1:7 twist, M4 barrel extension with extended feed ramps, and a carbine gas system. The barrel has an A2 style profile, is Mil-spec phosphate coated, and MP/HP tested. The upper is finished off with a Geissele .750" diameter Super Gas Block drilled and pinned to the barrel, A Geissele Super Modular MK14 M-Lok 9.5" Rail, and an A2 flash hider.

Geissele Rail: The MK14 is the latest entry to the Geissele line-up of Super Modular Rails. The new handguard design offers a smaller diameter and overall height to create a slimmer package. Included with the MK14 Super Modular Rail is an updated version of the proven Geissele Barrel Nut design, not only providing ease of installation but superior rigidity. The long surface contact of the 2.25” barrel nut interfaces with the receiver creating a platform that can be trusted to be straight and true the entire length of the free float rail. The MK14 is 3d precision machined using 6061-T6 Aluminum due to its strong, rigid and lightweight properties. 

Utilizing Magpul’s M-LOK technology in the 3, 6, and 9 o’clock positions allow the end user full customization and modularity of their rifle to securely mount lights, bipods, and other firearm accessories. The Geissele MK14 Super Modular rail is finished in a durable and long-lasting Type 3 Hardcoat Anodized

Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. These uppers are made for us right here in the USA by a mil-spec manufacturer.

Each upper is assembled to order with care, and test fired.

is the flash hider pinned and welded?
Ernesto on Jul 30, 2019
BEST ANSWER: The last thing I'd ever want is to pin and weld the end of my rifle preventing my ability to service the gas block. No, it's not pinned and welded. The only time that's done is when a barrel needs to reach the minimum length of 16" to be considered a "rifle" upper. If attached to a pistol lower such as one with an SBA3 brace, this upper in its current 10.5" configuration is completely legal.
I bought one of these a couple years back and my upper had an A forgery marking on the upper. I’m interested and buying another I love mine and it’s a great deal. But my buddy just bought one of these and his upper receiver has no forgery stamping is that how they are being shipped now? Thanks
Arnaldo on Oct 25, 2019
I bought three (3) of these uppers two months ago (SKU ending in 8075) and the Geissele Super Gas Block IS NOT Pinned to Barrel like these new ones. If I want the pinned version can I exchange mine? I haven't put mine into service yet.
Peter S. on Jul 25, 2019
BEST ANSWER: Hello,

We are not offering exchanges between pinned and non-pinned models.

Can anyone from PSA please answer/clear this up for me? Is the the Overall length of 19" including the A2 flash hider, or is the 19" from end of barrel/threads? Thank you very much for clearing this up for me.
Gary on Aug 12, 2019
BEST ANSWER: If your muzzle device is permanently pinned and welded that’s the only time you would start your measurements from that point. Check out this video from kotaboy32 in YouTube. He does a detailed break down of your question. https://youtu.be/IqkDlitW0v8
I see the gas block is now pinned. Is the barrel dimpled also?
david a on Aug 23, 2019
BEST ANSWER: no, it is not dimpled according to PSA themselves.
Does this upper come with the barrel nut tool in case I want to remove barrel?
ROLANDO V on Oct 31, 2019
BEST ANSWER: Mine did not, but you can use the spanner portion of most AR wrenches and it works. I used my Tapco to loosen my barrel nut.
Would this upper fit a troy lower?
Deweyh on Feb 21, 2020
BEST ANSWER: I’m not familiar with a Troy lower but I believe it will fit any brand mil spec lower. I have had it on a couple of other lowers and it works on all of mine.
Is this a pistol upper or rifle?
Milan W on Oct 18, 2019
BEST ANSWER: Both....It's an upper. You can put it on a "pistol" lower or on a "SBR" lower if you have one.
Do you recommend an H2 buffer with this setup?
Mike T on Feb 27, 2020
BEST ANSWER: i run it with an H buffer and it runs amazing.
I bought this a few months ago. There isn't a forge mark on the upper. Why is that? Who makes it?
david a on Feb 20, 2020
BEST ANSWER: PSA makes it. They are a vertically integrated company that makes much of their own stuff except where otherwise stated. So in this case the forging was PSA and the rails were Geissele.
If I put a SBA4 brace on with this upper will it still be legal?
Austin G on Aug 26, 2019

Please check your state and local laws before configuring a firearm.

Great for all-day usage
This is my go-to upper for classes. Mind you you will need a blast mitigator or suppressor to use it indoors due to the shorter barrel length. I found this length and weight to be ideal for repeated up and down drill usage.

Buy it, do it. Your welcome
What can I say, this is one of my favorite to shoot. Seriously like a tac driver. Added Gamma VG6 muzzle break, toolcraft BCG, Giessele Super Charging Handle and put it on a PSA pistol lower with EPT. Shoots like a dream. Don't think, just buy it!

Good value - changed muzzle device and buffer weight
Nice complete upper. The handguard is nicely finished and compact allowing for an easy c-grip. I removed the A2 flash hider before firing the complete gun. It was replaced with a Smith Vortex G6A3. I couldn’t see any muzzle flash under normal lighting at my indoor range. I didn’t try the standard buffer weight that came with the SBA3 set, but instead tried both a H and H2 buffers. H buffer was ok with consistent ejection at 3 o’clock. Keeping the H2 buffer in there as ejection was between 3-4:30 o’clock.

Love the quality!!!
This is my first pistol build. I wanted to build something low profile, sleek and simple. I would consider this my primary weapon and I realistically expect this to preform optimal from 0-200yds; although it's hard for me to see past 100yrds with irons. I have not shot her yet so I can't quote anything on it's performance.

It's a PSA Lower with a

- SBA4 /Magpul /PSA EPT lower parts kit.

-This upper of coures 5165490534

- PSA (No Logo) Nickel Boron BCG

- Radian Raptor SD-SL Charging Handle
