Barrel: A proprietary blend of Hammer forged chrome molly vanadium made by FN 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, and a mid-length gas system. The special A2 light profile barrel allows for better balance and portability over the standard A2 profile and is Mil-spec phosphate coated. Barrel is High Pressure tested, and Magnetic Particle inspected, to ensure quality and dependability, and is finished off with a PSA 13.5" M-lok Billet Rail, .750" low-profile gas block, and a pinned and welded A2 flash hider. The pinning and welding is makes the flash hider a permanent part of the barrel which brings it to the legal length.

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

Can I put a barrel shroud on this?
nite f on May 30, 2019
Do you have any idea when this upper assembly will be back in stock? Ballpark?
Ed D on Aug 20, 2018
How is the gas block secured? Is the barrel dimpled?
MattB on Jun 18, 2018
BEST ANSWER: The gas black is secured with set screws.
Will this upper be restocked??? I have waited forever!!
manuel q on Oct 14, 2018
BEST ANSWER: Right now.
when will this item be in stock?
Jonathan V on Oct 29, 2018
BEST ANSWER: Missed it.
Is this weapon’s barrel 14.7” made 16” with the pinned and welded flash hider OR 14.7” overall?
Michael J on Jun 5, 2018
BEST ANSWER: The actual barrel is 14.7" and when the flash hider is pinned/welded it brings it to the legal 16"
So, the gas block cannot be removed from the barrel, correct? Gas block ID vs Flash hider OD.
Glenn on Jun 18, 2018
BEST ANSWER: You can slide the gas block far enough down the barrel tho to clear the midlength gas tube from the barrel nut to take off the barrel
Can I get this with out the flash hide? I'd like to use it on a registered SBR lower with a suppressor.
Kyle E on Jun 4, 2018
BEST ANSWER: This item comes exactly as described. No changes, not options, no ifs, ands or buts. If you want a 14.7" barreled upper, go to the top of the page and click in AR-15 >Barreled Upper Assemblies and look for NON-pinned and welded uppers. You can even sort by 14.7" barrels.
Does this upper use a standard barrel nut?
Izaak K on Jun 18, 2018
BEST ANSWER: Proprietary barrel nut
14.7" .. can I put this on an AR pistol build?
V L on Aug 24, 2018
BEST ANSWER: You can, but this upper doesn't have to be on a pistol lower since the muzzle device is pinned and it brings the barrel to 16".
Does the upper come with the flash hider already pinned and welded to the barrel? I have seen some people saying that the flash hiders aren't pinned and welded by PSA.
Carson B on Jun 18, 2018
BEST ANSWER: They are both pinned and welded.
Can this be attached to a regular rifle lower?
Jr O on Jun 6, 2019
BEST ANSWER: If you mean an AR lower receiver chambered in 5.56/223 then yes. I have placed this upper on three different flowers with zero issues. Do not be concerned with rattles between upper and lower. If you are, they sell items to help eliminate the sound and keep pressure between both sections of your weapon
Can a suppressor be attached to this?
Mikael on Mar 19, 2019
BEST ANSWER: If it will fit a standard NATO A2 flash hider then yes. Otherwise you will have to change the muzzle device which will require a gunsmith since the A2 birdcage is pinned and welded on.
can the gas block be removed,over the flash hider?
jonjon m on May 29, 2019
BEST ANSWER: Who cares? Don’t change stuff just to change stuff. If you want a tinker toy buy some legos. Otherwise buy this and shoot it till it breaks.
psa, if I am buying this, I want the fn mark, if it doesn't come with it, what happens?
tog t on Apr 24, 2019
BEST ANSWER: I can't tell you what would happen. Psa would have to answer that. What I can tell you is that I do own this upper and it does have the fn mark on the barrel. Also I own 2 other chf psa uppers and they both have the fn mark as well.
If only it had a geissele rail and surefire warcomp?
Rusty W on Apr 26, 2019
BEST ANSWER: Statements with a question mark at the end are still just statements. Relevant questions about the unit listed would be good. This upper may not be your ideal set up but it is a quality, durable upper. I give PSA high marks for making it available
what kind of grouping at 100 yds you guys are getting?
Mario on Feb 6, 2019
BEST ANSWER: Groups with decent soft point ammunition are smaller than my 2moa red dot. I have no need for match ammunition myself but I am sure there is untapped potential given a more precise optic.
I have had this upper for a while with no problems but mine has the little plate between the halves of the rail where the hex screws clamp it in place. I understand that PSA can't use that plate anymore because its patented by someone else. Another PSA upper of mine had issues with the rail slipping forward when fired because there was no locking plate.
Before I buy another one if these I'd like to know how the slippage problem was addressed?
Doug B on Feb 3, 2019
BEST ANSWER: Mine has a standard cllamp on hand graud...Light Weight MLOK. It loosened up once when I first used it... I pushed it back, clamped a scope riser to the top, and lock tighten the screws.
Has not loosened up since....
This is by far my favorite PSA upper! 😃
Can I buy this with a different muzzle device pinned/welded?
Matthew B on Feb 1, 2019
BEST ANSWER: NO!!! PSA sells every item as you see it. What you see is what you get.
Can I install Magpol MBUS sights on this rail?
walt d on Aug 5, 2018
BEST ANSWER: Absolutely.
Will you off this with a key mod forend?
Lee W on Jul 25, 2018
BEST ANSWER: Probably not since it isn't 2012.
Any idea when this will be back in stock?

Perfect upper for an standard shooter.
This is the perfect upper for a combination of lightweight functionality and aesthetics at a great price. It shoots very precise straight out of the box, I highly recommend!

PSA upper comes with FN chrome lined barrel.
This upper runs great! It’s light weight and accurate. Shoots better groupings than my 16 BCM upper. Paired it with a WMD bcg, Geissele super 42 buffer and spring, and a CMC trigger. Really happy with how this build turned out.
Lightweight and runs great.

Great product for the budget minded person that wants it all at a great price
Some small finish discrepancies and miss matches. But the figment and quality of the components are great.
Great product! Everything fits great and 200 rounds with no issues.

Great upper
I’ve bought several complete uppers from PSA and the CHF 14.7 is my favorite. It’s the perfect length. It’s my HD riffle.

Horrible QA
I have purchased many uppers for far less money that had better quality than this upper. The flash hider looked like it was used on a previous firearm for years, the barrel was inspected with my bore-scope and found tool marks EVERYWHERE. I am looking to get my money back. So much for a recommendation from my brother-in-law to purchase from Palmetto. In my opinion this is the worse upper I've ever seen period!

Mixed Bag
I love the barrel's profile, and the FN logo stamping. The handguard has a plum hue, but is solid, and has no overly sharp edges. My biggest problem is that the A2 is overtimed, and causes the muzzle to dip to the right during fire. Ugly and raised weld, but that is purely cosmetic. Great value, but quality control holds it back from greatness.
