BarrelBarrel: A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as "Machine Gun Steel" by virtue of its 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 carbine length gas system.  Barrel is high pressure tested, and magnetic particle inspected to ensure quality and dependability, and is finished off with a PSA 12" Slant End M-lok Rail, a low profile gas block and a Palmetto State Armory Fluted Flash Can.

Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. Featuring a mil-spec finish, these uppers are made for us right here in the USA by a mil-spec manufacturer.

Flash Can: Palmetto State Armory Fluted "FLASH CAN". This is a solid 6061 aluminum device that is designed to direct muzzle gases and the muzzle flash forward, threaded 1/2-28, and black military-style hard anodizing. THIS DEVICE IS NOT DESIGNED TO REDUCE RECOIL, MUZZLE RISE, OR FLASH SIGNATURE. This device is designed to direct gasses and noise forward away from the shooter and enhance the weapon's appearance.

What's the difference between a chf barreled upper vs. a premium chf barreled upper?
Shaun C on Jul 11, 2018
Anyone know how often this comes back in stock?
S D on Sep 14, 2018
How long is the flash can ? Also I would like to run this upper suppressed, will a suppressor fit inside the guards in place of the flash can?
RON C on Dec 27, 2018
BEST ANSWER: You probably could run a suppressor on it, but it would depend on the size. The rail is pretty narrow vs something like a POF. The flash can does not have a way to unscrew without taking off the rail. The flash can is about three inches. I have suppressors and don’t even bother putting them on this upper. I bought it for the shorter maneuverability and lightweight of it. It’s not even that loud compared to an AR with a muzzle brake. Unless you’re going to be running it indoors don’t worry about the suppressor IMO.
What good is your "FLASH CAN" if it doesn't hide the flash???
Can I buy this upper with a Vortex flashider?
Tom L on Aug 27, 2018
BEST ANSWER: It's not a flash hider... it directs the flash forward.
Is this barrel entirely chrome lined?
Joe D on Jun 29, 2018
BEST ANSWER: Yes this barrel has the proprietary FN complete chrome lining. From the description: "In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability."
When will this be back in stock?
Joshua J on Mar 24, 2019
i bought one of these used it only marked "5.56 nato 1:7" was sold to me as CHF is this correct?
chris d on Jan 20, 2019
BEST ANSWER: The CHF barrel should have the FN stamp on it.
how much of a difference does the CHF barrel make than 4150V Chrome Moly Vanadium in the upper thats identical to this one?
cristofer c on Jun 21, 2018
BEST ANSWER: CHF just ads more longevity to the rifle, as it is designed to take more stress under sustained fire conditions. It is made of "Machine Gun Steel."
What is the inside diameter of the free float hand guard.?

Was consistently accurate at about 50 yards even after the barrel got nice and hot. Well worth the money!

Awesome Build
Paired with PSA lower build kit. Had a little wobble that a stencil cut out at the front pin took all the play out. No issues after 500 rounds. Runs flawless.

Great upper
Great upper that shoots well. The only bad thing I can say about it is my magpul backup sights were difficult to install since they fit very tight on the rail (not sure if that is a magpul issue or a rail issue)

Accurate reliable Easy handling HD pistol
Highly recommend. A little over 200 rds of m193 and some .223 so far. Slowed the cycle rate down with an H2 buffer. Though it shoots without issue with standard Carbine buffer but very fast cycle. Accuracy with the .223 Federal 55gr at 50 yds 3” with red dot. Plenty good for me in a 10.5 HD pistol And minute of man at 100yds. The adjustable brace is superior to the Shockwave blade for me. The FN CHF CL barrel needs a bit of shooting before the accuracy improved. But very happy with this Shooter. Will be using Hornady 73gr FTX .223 rds for HD.

Quality of this was not what i expected for $399.
I ordered a PSA PDW QCB lower 1st to mate this up to & the fit is super loose & the upper has blems desipte paying for a Non Blem Upper. So into this thing for $800 & have a rattlecan of a gun, obviously not happy.
