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 rate, 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.

BCG: Bolt is made of Mil-s\Spec shot-peened Carpenter 158 steel. Gas key is secured with grade 8 fasteners and staked per mil-spec.

BEST ANSWER: according to Nancey, this causes cancer in California.

good day
This upper assembly is advertised as an A2 upper but the photo shows a detachable carry handle (A3) receiver. Is this an A3 M16 upper clone then?
Dave M on Apr 26, 2019
BEST ANSWER: This upper features an M4 (A4) upper receiver with detachable carry handle as it states in the specs. A2 refers to the barrel profile.
Is the gas block pinned?
Hawkman on Feb 6, 2020
BEST ANSWER: Enter an answer to this question. It has a fixed front sight, which is also the gas block, so of course it’s pinned.
Is this barrel marked with CHF or FN markings?
John M on Feb 2, 2020
BEST ANSWER: Yes, it is laser etched with the FN Oval and "HF MP 5.56 NATO 1/7".
One can only assume it is govt profile?
Sean T on Nov 4, 2019
BEST ANSWER: Yes, the barrel is cut to standard A2 government profile specs. Only difference is that it is cold hammer forged (with extra-thick chrome lining), and the end where the flash suppressor is attached doesn't have the slight relief cut around it for use with certain out-dated sound suppressors (modern suppressors do not require the relief cut).
do the handguards have a heat shield?
Roy T on Aug 20, 2019
BEST ANSWER: Hello,

Yes, it does.

Premium upper with nitrided parts
Just opened my new upper premium 20” NATO upper today and I see it’s got a nitride bolt carrier and nitride flash hider. My assumption forking out the extra money for the Premium upper was that the BCG would be the premium phosphated model and not the nitrided part. The blue flash hider just looks bad and was not what I expected on the premium model. Called customer service and was informed that they ship with these items standard. Maybe it works good but c’mon...

Better than I expected.
M&P lower. Nikon P223 scope. Outstanding rifle that exceeded expectations. Decent groups. This rifle is stout. Doesn’t feel like a toy.

Nice 20” upper
Used this to build an A2 style rifle, even though it has a detachable carry handle (which I was aware of) it still looks great and so far has ran about 300 rounds flawlessly.

Great quality upper. Worth the extra in the long run for the chrome lining.

Great upper for the money
Used this upper assembly for a "Woodie" build on a PSA Minuteman lower. Rifle shoots great and is more accurate than I am currently. Took off 1 star as the A2 front sight is either just a little off or my eyes are crooked but zero for me at 100yd is about 10 clicks right, but it hits the same spot most everytime.

Not premium
Was not happy when I opened the box. The A2 flash was not timed correctly and was bright blue (Nitride?) and stuck out like a sore thumb. The delta ring was the same glossy blue, obviously left over "Freedom" parts. The receiver was milled incorrectly, one side wall was almost twice as thick as the other. Finally PSA decided that a nitride BCG was good enough for an FN barrel. With that being said I should have sent it back before I cut the "tamper tie strap".
Now its just overpriced spare parts.
Uneven walls
Shiny Flash not timed on phosphate FN barrel, might as well be orange.
Shiny delta ring against hard coat.
