Add To:

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 5.56 NATO, with a 1/7 twist, M4 barrel extension, and a carbine-length gas system.   The M4 profile barrel  is Mil-spec phosphate coated, High Pressure tested and Magnetic Particle inspected.  Barrel is finished off with an F-marked front sight post with sling swivel, standard handguards and an A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is hard coat anodized black for durability. Featuring T-marks, these upper 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.

Best upper for any amount of money
I have had this upper for well over a year and it's been great. CHF FN barrels are the very best there are. I wouldn't consider anything else (for any price) and PSA is one of the few places you can get FN barrels. If I ever build another one PSA will be my first stop.

my 2nd build better than the first??? Looks like it!
Initial review of this upper and a few things I learned to look for: this is the second of this exact upper that I have ordered. First one was fantastic except for the front sight post being off a few degrees to the right. This resulted in a windage correction of about 20 clicks to the left at 25 yards. Still used that upper for a custom build for my wife (PSA lower/LPK/EPT/NiB BCG BCM ambi charging handle and ambition safety Magpul MOE grip/aluminum enhanced trigger guard/ACS stock) and it's an awesome upper. Once it was zeroed I put about 150 rounds through it of different types of ammo from .223 TulAmmo to green tip 5.56mm and had no issues at all (save getting the very first magazine in there and chambering the first round after that flawless)! Got that one at $369.99. Picked up this upper at $299.99. Haven't fired yet or fit to the lower but things I've noticed: front sight post is dead-on this time. Verified this using a red dot and zeroed MI rear folding back up sight so the initial impression is good. All of the exterior looks as it should (Awesome!). On another project rifle from a far LAZIER company (not PSA) I swapped out the hand guards with both MOE and MI drop in hand guards and both were off several degrees with the tops of the rails at about the 1 o'clock position. The barrel nut timing was off and the nut was on so tight that my local gunsmith broke his wrench after soaking the upper in solvent for half a day so still unable to make it budge. NOT THE CASE HERE. Everything lines up! Fit and form look great now just doing a little more custom work on the PSA billet lower before finishing everything and taking to the range. For the money PSA does an awesome job and I'm very happy with everything I've purchased from them (second build multiple parts ordered on other occasions!). Customer service was responsive when I had questions so no regrets about going this route again. Will update once complete and firing but for now highly satisfied with the product!

Great shooting
I bought one of these for a build for my wife - she regularly pops prairie dogs out to 200M with her upper and Nikon scope. I am anxiously awaiting another to build mine.

CHF badass upper
It takes a beating. Others are good but this is the best upper PSA offers in my opinion. Built to last. I believe that chrome lining does affect accuracy but mine is incredibly accurate. Well worth the few extra dollars. Shipping has always been within a week or two. Get one put it on your lower and get out there and have some fun. Get it dirty. Run it ragged. Try to wear it out. What are you waiting for? Give them your money already. It ain't gonna buy itself.

Love this upper - my favorite one in my collection of 4 AR's
This is my favorite Upper out of the 4 I have.
Put this on a Spikes "Jack" Custom Lower with PSA EPT parts kit and it runs flawlessly.
Added a Matrix Diversified Ind. "Reaper Black" Magpul furniture set to finish off the skull motif of the Jack Lower.
Shoots anything and is rock solid and dead on accuracy.
I kept checking for weeks for this to come in stock and finally got it.
You can't beat PSA's CHF barrels and this upper should be alot more $ than it is.
Always been a fan of PSA and will be forever after getting this CHF upper for such a great deal

Love it!
Finished out my build with the PSA lower I've had sitting around for some time. Head spacing was spot on front sight is aligned perfectly. Shoots like a dream. No complaints with the CHF FN barrel carbine length upper. Extremely small amount of play between my upper & lower. Thanks PSA!

Awesome upper
When I first got this I actually called to do a return. There was a piece of foam that had fallen in the chamber and I didnt realize it. It wasnt letting rounds chamber all the way and I thought it was defective. After running a cleaning patch through the barrel out popped a piece of foam covered in black stuff. Im guessing it fell in when they were boxing it up for shipping. Ever since then I have had zero problems. This is a great upper and very accurate. Ive got probably 1000 rounds so far through it with no fte/ftf. I gotta say i was pretty mad when I thought the chamber was cut short at first though haha.
