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.

Woody S on Jul 19, 2018
BEST ANSWER: Right now
Does the barrel have the FN roll mark?
Shawn C on Dec 11, 2018
BEST ANSWER: The front sight comes rolled to the left. Canted. Unable to sight in. exceeds the mechanical limitations of the carry-handle sight.
When will this be available?
James on Oct 30, 2018
Is PSA ever going to make this with the permanent carry handle and rear sight? Trying to build the Iraq lower so it is as close to what I carried over there as possible.
Pete L on Jan 23, 2019
BEST ANSWER: I have seen the A2 upper on Brownells site
When are these going to be available again?
Brian on Nov 19, 2018
When will these be in stock again?
Aaron H on Dec 30, 2018
BEST ANSWER: Now, now, now , now
To the fellow owners of this kit, Did your upper have T markings on it? None of the PSA uppers that I've bought had T marks on them even though they are advertised as having them.
Dave P on Apr 17, 2019
Is there any difference between this and the freedom variant other than the barrel?
William G on Apr 17, 2019
BEST ANSWER: Does the freedom have a canted front sight? The 20" CHF, Machine gun steel, hype, hype, hype, comes with canted front sight, and no response from PSA's customer dis-service. Thank you for no-service PSA.
Is this a government profile barrel
(heavy in front of the handguard and thinner under the handguard)?
Richard L on Dec 10, 2018
BEST ANSWER: This is a very special barrel with a very special front sight. They drill and pin the front sight tower on crooked or leaning to the left. You'll use up all of you windage and you might be zeroed at 25 yards. At 50 yards, you'll need to hold off on the target and make hook shots!
Is this able to accept a bipod?
Max on Apr 17, 2019
BEST ANSWER: This is modeled after A2 style rifle and has no provisions for accessories
With this Hopper is it possible to put 1 round handguard on the left side in a triangle handguard on the right side to compensate for the crooked front sight. Myfrontsight is only one inch off to the left crooked just didn't know if this would help??
Mike D on Jun 16, 2019
BEST ANSWER: I modified my whole upper and put a free float tune on it and a UTG quad rail and a low profile gas block, my advice to you put a scope on it and let it rip, it will hit 600 yard bullseye no problem
Is this the same upper used in the Premium 20" Rifle Build Kit, SKU# 8818?

PSA 20" CHF Rifle Length 5.56 NATO 1:7 Premium Rifle Kit - 8818
PSA 20
PSA 20" CHF 1:7 A2 Rifle Length 5.56 NATO Premium AR-15 Upper Assembly - with BCG/CH
BEST ANSWER: I would have to say yes. All of the 20" A3 style rifle kits have the exact same description for the upper and specifically say 'hard coat black anodized'. Some of the free float kits don't say 'black'.
Would this be a good starting platform for CMP Service Rifle competition? That is, practice, practice and practice some more, then rebarrel it with a match barrel, full float hand guards and upgraded A3 rear sight assembly. Thoughts?
Tom H on Dec 27, 2018
BEST ANSWER: Enter an answer to this question.I would have to say NO. The hand guard is not free floated. If you sling up tight like you will need to, to shoot your rapids, you will experience both elavation and windage shifts. And that shift will not be consistent. Get yourself an upper with a float tube that is set up specifically for service rifle competition. This advice is from a Distinguished Rifleman and P100 (rifle) Shooter.

Also, forgo irons now that optics are legal. Get a good two stage trigger that will lif5 4.5 lbs. LaRue make a good one at a very reasonable price.
What is the length of pull (LOP)? wonder a youth can use it. Thanks.
libarrel on May 27, 2019
BEST ANSWER: Look up the M16A2 specs. They are on line.
Can I replace the round hand guards with original A1 triangle hand guards? If so, is it easy as popping the round ones off and installing the triangle ones? How should one install triangle hand guards in detail?
PAUL J M on May 24, 2019
BEST ANSWER: i haven't changed them myself but you should be able to replace them with any drop on rifle length handguard
One question
For lower receiver Buttplate (with trap door), is it metal? or plastic?
Jonny L on May 1, 2019
BEST ANSWER: Plastic. Has a plastic-hollow sound, kind of a twang sound if you shoot with it. Try to avoid dropping it.
Does this include an M16-style carrying handle/rear sight?
Cara M on Apr 1, 2019
What’s the length of the Handguard?
Andrew Q on Feb 18, 2019
BEST ANSWER: 12 Inches
What lower is recommended to be used with this kit?
daniel852 on Feb 8, 2019
BEST ANSWER: Any stripped AR-15 lower for NATO 5.56mm or .223rem you have should work with this kit.
Does the stock have a trap door for cleaning kit?
Otlando C on Dec 28, 2018
BEST ANSWER: Yes it does.
What is the overall assembled length of this rifle?
Tim H on Jun 10, 2019

Great rifle
Got the rifle kit as a project for my son and I to build together. Everything went together fine except for the rear take down lug on the upper had to be drilled out for the pin to function properly. Otherwise, it was a strait forward AR build and shoots great.

Fun rifle
This kit is well worth the extra money, not only do you get a fn barrel, you get the other premium parts as well including the FCG and BCG.

I truly like this combination but haven't really been able to try it out completely. It matches the setup I had while serving in RSVN except for the carrying handle and rear site.

Canted FSB
Ordered two kits in April at $550 each. Assembled one and took to the range. Could not zero. Factory Colt carry handle sight that had been zeroed on another rifle ran out of adjustment to the far right and was still 2 inches left of bullseye at 25 meters. Visually verified FSB canted to the right. Inspected the second upper and found it to be canted also. Working on returning both to PSA. Have 2 of the 10.5” CHF uppers and both FSB are true and barrels are very accurate for the length. Another nail in the coffin is that I paid $50 more a kit than the current price for defective products.
