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 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.

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
If I put a SBA4 brace on with this upper will it still be legal?

I see the gas block is now pinned. Is the barrel dimpled also?
david a on Aug 23, 2019
BEST ANSWER: I am it sure but with the block pinned as well as it is I can’t see any added benefit in dimpling the barrel.

Geissele rail mounting bolts overtightened many times beyond Geissele specs
Stripped mounting bolts attempting to remove Geiselle Rail from PSA upper receiver. Geissele specs are printed above the bolts "Max torque 8 ft-lbs". Set fat wrench to 10 ft-lbs. No luck. Gradually worked up to to fat wrench maximum (over 70lbs) and the bolts still wouldn't budge. Assumed PSA used red loctite so heated bolts with torch and used manual hex key. After torch, first bolt freed at force in excess of 70lbs.
Second bolt stripped entirely. Photos attached. No

Picatinny Rail atop PSA upper seems to be out-of-spec (2 part review)
Purchased July 2019. First noticed problem with size of picatinny rail atop PSA upper receiver when mounting SIG Juliet 4x magnifier. Factory quick detach mount fit just fine on the Geissele portion of the picatinny rail but had to force it to fit the PSA portion. Assumed SIG was to blame and picked up a pair of Scalarworks Peak Iron Sights. They don't fit either. Both fit just fine on AERO upper receiver. Photos attached with proof of purchase.

Rock solid pistol upper
Extremely high value upper. This barrel is very accurate, capable of moa groups with the right ammo. The MK14 rail is very skinny and perfect for thumb over bore hold styles. The pinned gas block gives you confidence that it will never move despite how hard you run this upper. This is a much better and lighter upper than the MK 18 and half the cost. Does not seem terribly over gassed and mine shoots softly with a h2 buffer and JP silent capture recoil spring. I challenge you to find a better upper for the price.

Bombproof
If you like your rifle to feel and act the part of a rifle not a safe queen (or if you so prefer your AR Pistol) this is not going to disappoint. As solid as a brick. It is heavy but let's get real here. The barrel is FN (solid as they come, DD is another that could compete). The whole setup is made to play hard. So if you want the lightest thing ever skip this. If you keep yours in the safe so it looks pretty, that's up to you but there are cheaper ways to do it, and quite frankly would be doing this upper a disservice by not being put to use. I absolutely love it. (In case you couldn't tell)

Superb Upper, superior quality
I can't begin to express how impressed I am with this upper. I have seen other top name pistol upper and this upper is on par with or better than those. Fit and finish are top notch. Love it and will be guying this one again and other Geiselle/FN equipped uppers.

Speechless!
Not much I can say about this. It's perfect. I'm left speechless. Sub MOA groups I get outta this barrel at 100 yards. Was going to whine about them pinning the gas block. But it was set perfect.

$499 is the best deal for this upper in the world. The barrel is incredible. The handguard is light and has a great feel. Buy it now.

great value for the price
Giving 5 stars for the value, but would be a 3 stars for the fit and finish though. The rail came unaligned by 2-3 degrees. Anti rotation screws were full of aluminium shavings. the gas block is also off by a few degrees. i can honestly go past that, and simply take a minute to fix the issues with blue loctite.

Other than that, with a standard carbine buffer weight and spring it is visibly overgassed, gonna go with a h3 buffer. Very pleasant to shoot even with the a2 birdcage.

I can only recommend you get yourself one, and hoping PSA can fix the rail fitting. Still leaving a 5 star.
