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.

Heavy Duty M4 upper
Wanted a current mil spec M4A2 upper and I guess this is as close as I can get for the money. FN stamp on top of bbl. 1/7 twist. Chrome lined. Mine came with a very dirty bore. Assume that it was from testing. BBl's and uppers spec'd out like this are hard to find at an affordable price. Another vendor made a big deal out of these when the specs changed and they became available on the civilian market. As soon as they came out, they were gone never to be seen again. This one was hard to find on PSA website. Lots of search queries with different key words. As soon as I found it, I ordered it. I have a very nice M4 that I put together from PSA upper and lower with a hand guard from MWI, SOPMOD butt stk, Acog on the rail and it's G2G. Couldn't be happier with it. Now I have a replacement upper. Nah, it will probably find a lower to hook up with eventually.

Paid for a premium and got a blem...
Paid for a premium and got a blem. The front of the barrel has a ring of plier/chanel lock marks from when the flash hider was installed. How this got past QC, I don't know. It's cosmetic and the rifle will surely work, but definitely not worth the premium price.

Awesome rifles, love that barrel!
I am very happy with PSA build quality. My colt has nothing on either of these rifles.
Shoots great with IMI 62gr. Not so much with the lake city ammo, Both rifles outfitted with
PSA premium bcg’s. Flawless performance,
Great value!
So happy with them that I also bought/built a
20” A4 with the same kind of FN barrel.
Can’t find any difference between these and my Spike’s tactical either.
PSA should buy out colt, then they will have the name to go with the quality that people think they can only get in a fancy brand name!
I liked it so much that I bought two!
One is the free floater with the Sig Romeo5.

Great value - better accuracy than anticipated
I've got about 500 rounds through this upper and am very satisfied so far. I've had very good results regarding accuracy as well. Cheap 55-grain ball ammo grouped at about 1.5 - 2" at 100 yards using a simple bench rest. This barrel is not free-floated and I have 54-year old eyes.
