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.

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....

PSA, what does this upper weigh?
Thank you in advance for your answer.

BEST ANSWER: Using my bathroom scales the upper without BCG or charging handle weighs 3.8 pounds..Lee
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?
Sidney E. P on May 24, 2019
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.

Glad I waited...
Didn’t plan on the review but reminded to leave comments here they are: last week we put full soda cans at 200 yards and hit them.
I have a heavy barrel and waited for this lightweight not sure how it would fare. Compared to my 16” light carbine this is just awesome. I have a new 100+yard favorite rifle, more fun than my bolt actions. This is a target rifle. Thanks.
Yeah, I waited like 4 months for it to be back in stock...and I’d do it again.
rifle length gas...this is what it looks like.
Palmetto upper with FN barrel.
Paired with old bushmaster with a better trigger, long buffer tube and vortex strike eagle 1-6.

Great upper
I was going to buy a bolt rifle, but after cataract surgery my left eye vision was so good I decided I needed to switch to lefty. I am 71 and have always shot right handed. Being left eye dominant also Influenced my decision. When this upper came up I went for it; and have no regrets. Paired it with a Precision lower and magpul hardware. Bought the bolt and trigger from PSA. It seems to like 62gr. green tips better than 55gr. Have got some 77gr. but have not had a chance to try them yet, just been shooting the cheaper stuff till I get used to shooting lefty and used to the rifle. Shooting 2 to 3 inch groups at 100yd. This upper is shooting lots better than me right now; but I will improve. Also Kudos to Magpul for sending me a new allen head bolt that goes in the front of the trigger guard. They did so at their expence; so thumbs-up to them. I would certainly buy from PSA again.

5 star only with an astric for quality controll .
Very accurate 1/2 moa at a 100. Only one problem it would not cycle or lock back. It came with a gas port size of 0.068 in. after correcting to 0.096 in. it now runs like a sewing machine using steel case or brass. Also changed out stock to A2 with rifle length buffer and spring.

Fantastic "Tack Driving" upper!
Bought this upper because of the FN barrel. Finished the build on a PSA lower, with POF flat blade trigger 3.5# pull with KNS pins. Had it out at the range today and blasted 250 rounds through it. I have 2 words "Tack Driver". Fit and finish are perfect, handguard is perfectly aligned and Rock solid. Pair this barrel with a VG6 Epsilon muzzle brake, and you have a very soft shooter. Next build I'll definitely buy this upper again. Value can't be beat.

Great parts but need more assembly care
This was the first of my FN CHF assemblies. I thank PSA for offering so much value but this thing came with a loose rail and a loose gas block that was tilted, causing the gas tube to touch one side of the rail. Further inspection showed no grease on the barrel nut. So once again, great parts but this one is coming apart for re-assembly.

Best Upper For The Money
Great upper receiver, ran 500-600 rounds through it non stop, getting snowed and rained on in 20 degree weather. Soft shooting, accurate, consistent. I was hitting about 0.5"-1.0" groupings at 80-100 yards. Love it.

Nice Upper. Excellent fit. Quite happy with it.
Nice upper. Mated it to a Palmetto MOE Lower. Added a stainless steel bolt carrier group and an Anderson Manufacturing charging handle. Fit and finish is good with the exception of one small spot on the barrel. Only I can notice it.
Looking seriously at purchasing another one of these uppers for another build. Will be mounting a 3.5X10 power scope on it soon to test it out at longer ranges and bench it to see how it groups.

Best Overall Shooting AR-15
I've had this upper (mated to a PSA lower with Geissele SSA trigger) several months now, and have put all manner of loads through it: 62gr handloads; M855(PMC XTAC, IMI); Hornady Frontier 75gr HPBT; Handloaded Sierra 69gr and 77gr MatchKing; and various 55gr factory loads. It shoots everything accurately (the only rifle I own that will do that). I am not a great shot, but if I am on, it easily will shoot sub MOA. Fit, finish, and reliability have been top notch. If you are limited to one AR-type rifle, I would highly recommend springing for this upper.
