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 required 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 .223 Wylde, with a 1/8 twist, M4 barrel extension, and a Rifle-length gas system. This 18" A2 profile barrel is Mil-spec phosphate coated, High Pressure tested and Magnetic Particle inspected. The barrel is finished off with a 15" PSA Lightweight M-Lok free float rail and an A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is hard coat anodized black for durability. Featuring T-marks, these upper receivers are made for us right here in the USA.

Each upper is assembled to order with US-made parts, and test fired to check gas function. 

**Does not include bolt carrier group or charging handle.

How are you supposed to use it if there is no BCG or handle? Is this only a display piece?
nite f on Jun 8, 2019
BEST ANSWER: This should be a question that disqualifies you as a buyer.
What's the weight of this upper ?
Copperhead on Apr 18, 2018
BEST ANSWER: 3lb 11 3/4oz without the BCG
Is the barrel truly thinner under the hand guards like a govt profile?
Sean T on Apr 24, 2018
BEST ANSWER: The two I received were. There is a heavy version that you can also buy here that has the fat barrel.
Can I use a mil spec buffer and spring? Or do I need rifle length?
Joe A on Jul 24, 2018
BEST ANSWER: The Mil spec is the carbine length. But you can use either carbine buffer & spring or rifle length. Either one should work ideally. Now if you have issue with one type, try it with the other....
Why won't PSA answer the first question?

PSA, what does this upper weigh?
Thank you in advance for your answer.
Cynthia N on Jun 19, 2018
BEST ANSWER: Using my bathroom scales the upper without BCG or charging handle weighs 3.8 pounds..Lee
is the gas block pinned? Barrel dimpled?
Rafael on Jul 3, 2019
BEST ANSWER: Gas block does not appear to be pinned or dimpled, but I would not let that stop you from buying this upper-- it has an **FN made** barrel for a very good (great?) price. If you want a cromed-lined, 4150-type steel barrel with a 1/8 twist rate and 223 Wylde chamber, then this a very good upper. My advice is to buy it!
Can you shoot 5.56 ammo out of it??
Dwayne D on May 27, 2019
BEST ANSWER: Yes you can. .223 Wylde was designed to shoot both 5.56 and regular .223 safely.
Does this product completely built?
Greg S on Apr 6, 2020
BEST ANSWER: Just add your favorite BCG, charging handle, with your lower. Will need to add sights. This is a very good upper that's built.
Is it safe to assume that the wylde chambering has the same bolt lock up as the 5.56? Meaning does it take a standard BCG?
Russ B on Apr 1, 2020
BEST ANSWER: Yes, I am using the BCG that came with an MP 15. It does work with a 5.56 BCG.
I've had mine for over a year or so and I am very happy with it!
Is this "lightweight" MLOK upper a 'pencil' barrel upper? The text says, "This 18" A2 profile barrel", suggests it is not a lightweight barrel model upper. I definitely don't want the heavy front end of an AR-15 A2 but the picture doesn't show this so, is the text wrong?
BEST ANSWER: Lightweight is referring to the hand guard. The barrel is a heavier profile, and definitely not a pencil. It’s a great upper and is surprisingly accurate for a chrome lined barrel, but might not be what your looking for if going for a featherweight build.
How many grooves does the barrel have ? Thanks
Larry on May 10, 2020
Is this upper a free float barrel setup?
Jeffery L on Apr 29, 2020
BEST ANSWER: Yes, and I can say super accurate. I have mine set up with a 0 to 8 Vortex Strike Eagle and it shoots 5 round groups under a nickel.
is this compatible with a BCM lower ,I am new to this rifle type?
jimmy on Nov 8, 2019
BEST ANSWER: I would think it would mate with any standard lower. I’m using this upper with a ruger lower with no issues. Tight fit.
I am new to this. What pins do I need to put on a lower? thanks

PSA 18" CHF 223 Wylde 1:8 Rifle Length 15" Lightweight M-lok Upper - No BCG or CH - 5165448089
PSA AR-15 MOE Lower Receiver with Two-Stage Nickel Boron Trigger, Black - No Magazine
PSA AR-15 MOE Lower Receiver with Two-Stage Nickel Boron Trigger, Black - No Magazine
BEST ANSWER: Pivot & takedown pins. Likely included with this lower. You need a charging handle and bolt carrier group for upper to run it. Any standard BCG for 223 will work.
Does this come with an adjustable gas block?
Dan H on Nov 6, 2019
Will these CHF barrels start getting dimpled like the pa15 gen 2s? May have missed it if stated elsewhere.
Goosefraba on Sep 4, 2019
BEST ANSWER: To date mine has not gotten dimpled. I also have not shot a lot of rounds through my rifle, nor have I fired rounds in rapid succession, so the barrel really never gets a chance to really heat up.
Could I get this with a railed flat top handguard instead of the dip down smooth top one being offered?
Tom R on Aug 12, 2019
BEST ANSWER: Theres one on a daily deal right now. just do a search for chf
Waiting on mine to arrive also ordered a PSA Custom 5.56 DLC Coated BCG for it. I assume the headspace was checked and this BCG will drop in and run? Experiences?

SUB-MOA out of the box
I called this build the "Project Poor Person Precision AR" until I shot groups at 100 yds and printed 0.5" 5-shot groups in a stiff crosswind with some handloads I had lying around (see photos.) Now I call it my "Precision AR." Accuracy is astounding for the price. Riding in an Aero standard ultralight mount is a Vortex Diamondback Tactical FFP 4-16x44, which makes this budget-friendly build easy to shoot accurately. A CMC drop-in single-stage 3.5lb trigger also helps. The gas system is a little bit forceful when suppressed, despite being a rifle-length tube, and I'm currently running an H2 buffer to achieve 3 o'clock ejection pattern. Bolt carrier group is BCM, but I'm still waiting on the Bootleg adjustable one to arrive to further tune the gassing. The screws on the gas block and handguard accepted a little bit more tightening from me when the upper first arrived, so time will tell if the lack of dimples becomes a problem. The handguard is slim, light, and minimalistic, and I'm excited to see how it carries in the field hunting marmots, coyotes, and prairie dogs at range. Overall I'm blown away by the value and performance of this PSA upper, and I'm preaching to anyone who will listen.
1/2 MOA before any devoted load development; a random 55gr Varmageddon handload I had lying around
Consistently 1/2 MOA with my random 55gr Varmageddon handload in MIXED HEADSTAMP range-pickup brass.
Prints factory PMC 55gr FMJBT at about 1.5 MOA
Vortex Diamondback Tactical 4-16x44 is a spectacular pairing for this budget precision build

Love it!! Tight chamber
Very reliable, well assembled. Out of the box mine did not like steel-cased ammo or Winchester white box if I recall. It may now that I have a thousand rounds through it though. Everything else runs just fine. We'll see how it holds up, supposed to be real tough.

Great upper!
Extremely happy with this upper!

Solid Feel and Lightweight
I HAVE NOT SHOT THIS YET. Just received this today, and by all means looks fantastic. Exactly what you would expect from PSA. I have another FN barreled upper and works fantastic. The only thing I thought might be a concern for some buyers is there are a few blem spots on the upper. ( I think it adds character/uniqueness) This does not effect me, but if someone that is bothered by spots and imperfections in the forging might not like this. However the price is right and worth the barrel! Just waiting on my optics setup and can't wait to shoot this.

Jams with M193
It feeds 62 grain LC , 223 GECO and PMC xtac m193.
Bullet jams in chamber and pulls out of case using federal Independence and PPU m193.
Powder goes everywhere and you have to knock the bullet out with a cleaning rod.
From what i can see it looks like a sharp shoulder at the entrance to the bore.
Turns your rifle into a club.
I have had it too long so no warranty i guess.
Can't trust your life on this one, back to 5.56 chambers.
Barrel is accurate though.

Great Upper!
This upper is a smooth shooter. I have put nearly 6,000 rounds through and its solid all the way around.

Fit and finish was good, everything lined up as it should on my Colt 6920 lower. functioned perfectly. Only reason for 4 stars was the gas block was very noticeably canted and was actually against the rail. It was a quick fix but should have been caught be QC.
