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. 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 many bullets can I shoot before I need to clean it?
nite f on May 23, 2019
BEST ANSWER: I usually fire about 4 rounds between cleanings. If you're lucky, you may be able to get 5 or 6 rounds down the barrel before it jams up on you. Hope this helps.

Is this the same barrel as a spikes chf fn barrel?
David F on Jul 30, 2018
BEST ANSWER: It is just what it says it is. It is rollmarked fn and is the best you can get. Spikes uses some fn barrels. This is the carbine length fn barrel that has better steel and thicker chrome than other barrels. There is not a chrome lined 16” barrel out there that wears better or is more accurate than this one.

I was really excited the day it came in and I got a chance to fire it, it shot rather accurately at 100 yds with irons.

Reciever left me with some questions
Okay, I really hate writng a review with negatives and I've held off but I have to say this. First off the upper had no T marks as advertised and secondly there's no forging mark. Did I get an inferior product? What did I buy?

AWESOME product.
Finest upper I’ve owned. Chrome lining definitely helps with heat and cleaning. Shot grouping is FANTASTIC. Great deal on a quality FN barrel.

You will not find a quality upper any cheaper!
Ordered for the barrel. Changed out the hand guard when I got it. Nothing wrong with the original, just my preference. The barrel is top notch and I have no doubt it will last a long time! Thanks PSA!

Its Machine Gun Steel, Best of the Best.
CHF FN Barrel. Does not get much better than this. Has the fn roll mark followed by specifications foward of the fsb. No psa logos anywhere on barrel or upper. Next purchase will be the m4a1 profile of this barrel that psa currently sells.

Good value
I waited on a CHF FN pencil barrel but it doesn't look like they will ever sell those again. This is beefy, M4 profile, and barrel made by FN. What else can I say?

This upper is worth twice the price. Barrel is top-notch, F&N stamped. Im shooting Sub-moa groups with MG rounds out to 50 meters and 1.0 to 1.5 at 100. Very pleased.
