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 rifle-length gas system.   The A2 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.

Only buy psa premium
Psa has changed their premium line a little bit over the years. I like how the FN barrels actually have a FN stamp on them now. I dislike how they chamged the material of the delta ring to what appears to be aluminium. My older PSA premium line uppers have a better looking and feeling delta ring (phosphate vs anodized finish). This 20" went to create a M16A3ish rifle and that delta ring needs to go.
Shoots m855 @ about 4 moa.
I will continue to buy PSA's FN barreled uppers

this was my first upper purchase from psa, quality is good accuracy is good when using my el-cheapo trs-25, and when using good lapua 55 grain ammo, good product no issues to date with functionality.

This is one of the best made barrels I own. Bought it to finish my A2 clone, and could not be happier. The barrel seems to hold up better with the binary trigger I use to mimic the tri burst on the military A2. Although I will say the Palmetto phosphate barrel I replaced was also very accurate.

Don't hesitate
Awesome upper.

Mated to a PSA A2 lower, LaRue MBT trigger, Mil-Spec carry handle rear sight and CBC MagTech 77 grain SMK Hollow Point (Mk 262 Mod 1 clone), I shot an 0.716" 4 shot group (1 called flyer) from the bench.

A genuine 20 CHF chrome lined FN Barrel! What’s not to love?!
A very nice piece of equipment. I was looking to build a full size AR15A4 and didn’t want to spend a lot. But then this became available.
20” , CHF, chrome lined, made by FN!?!
Too good to be true?! No! It’s really sweet!
So far shot about 120 rounds of xm-855.
No problems whatsoever, using the clamp on carry handle , open sights, in the black on an 8” bull @ 100 yards no problem. Will get more precise later but so far a very sweet and soft shooting rifle. Also using a PSA bcg and charging handle. Sitting on a Spike’s Tactical lower I built. Fits nice!
Beautiful AR

Extreme Excellence
The AR-15 / M-16 series rifle was the finest military grade weapon created next to the M-14. Those or whom know of such are aware of the environment to which they are put into. The material standards guarantee success as to their function and dependability. Upon use and test in comparison its kind of like driving a Cadillac vises a Chevy both of which were at one time very well made, but the 20" CHF stands out. as and excellent build and function.

I highly recommend this upper for a2/a4 build. The FN chf barrel shoots great! When paired with a2 rifle length lower function is perfect. Upper is not overgassed. Paired with psa carry handle sight was perfect. No windage correction needed (front sight aligned properly). FN barrel + milspec upper= no brainer. Great setup!

Good Upper
FYI not sure if this applies to all these uppers or just the one I got but I was not able to attach my Griffin Armament M4SDII silencer to it. The gate Lock would not fit through the bottom rib as it was slightly over sized. Other than that the upper is really nice and was exactly what I wanted for my build.

Very pleased.
Received it yesterday which took about two weeks. Took it to the range this morning and was amazed how nice it felt with that 20” barrel. Hardly any recoil and very accurate with minimal site adjustments out of the box. Can’t beat the price anywhere for the quality of this upper.
