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.

is this the bestest gun I get?
nite f on Jan 4, 2019
BEST ANSWER: It made up into a really good carbine. It looks good and functions 100%.
Which bcg is included in the kit?
Charles W on May 26, 2018
BEST ANSWER: My kit came with the premium full auto bolt carrier group.

The bolt is marked MPI HP.

It has the PSA Cannon and Ball logo laser etched onto the side of the carrier.

Taking the bolt apart revealed black spring insert and black donut.

Gas key was properly staked.

I have heard others say they received a lower grade bcg than I have described. And Ive heard others say they got the premium full auto bcg like I did. I think it depends on what PSA has available. I think I got lucky.

My buffer also is black and has the PSA ligo on the flat head part if the buffer

Is this like a Colt (the quality of)?
Manny M on Dec 11, 2018
BEST ANSWER: I own both a Colt LEO6920 and a AR built with the 505097 PSA kit and an Anderson Lower. The fit and finish of the PSA is every bit as good as the Colt. The Hammer Forged FN barrel is very accurate. I have had 4 friends build the same rifle after me and they all are as happy as I am with the PSA. Save your money, buy the PSA.

Jerome W on May 27, 2018
BEST ANSWER: if you gotta ask that question then you need to do your homework on the ar platform.

So Aero makes the receivers for you and then you do the final machining and anodizing?
Grumpy on Mar 21, 2019
BEST ANSWER: I don't think this is correct. I'm pretty sure PSA buys the forgings from one of the forging houses and then CNC machines and finishes the lowers in house.
Will this upper accept a standard bayonet?
john111 on Jun 13, 2019
BEST ANSWER: A standard bayonet will go on this upper but it will fit loosely. Because this upper has a 16 inch barrel instead of a 14.5 the ring on the bayonet handle that normally holds on to the flash suppressor will be around the barrel where it is not tight.
Is this a SOCOM (thick) profile barrel ?
Tommy on Aug 26, 2018
BEST ANSWER: no, standard M4 profile as described above.
FN logo out by front sight.
What size hand gaurd can I fit?

BEST ANSWER: Of course. It's a build kit. It comes with everything but a stripped receiver and a rear sight.
Is bcg and bolt chrome plated also?
Frank on May 3, 2019
BEST ANSWER: No. It is a normal bolt carrier with a phosphated exterior. The inside of the carrier where the bolt and gas rings ride and rotate is chrome plated.
I want this kit but in a midlength 14.7", pinned and welded?
Short Round on Mar 22, 2019

Great kit for the money
Great kit for the price, especially with the lines barrel. Will most likely swap out the bcg, and may swap rails but not sure yet. Put a few hundred rounds down range so far, shoots strait and functions very well.

Top shelf upper
These uppers are top shelf. Very well made and the FN barrel is the cherry on top. Very accurate. Very happy with mine!

Great kit at great price
Got this kit a couple weeks ago and built a couple days after I got it on a Anderson lower. Everything fits perfect and looks great. Oilled everything and sighted in the rear sight on the carrying handle that I attached to the rail. Once I got my sight zeroed in the rifle shoots accurately using federal 62 grain 5.56 so the FN barrel is excellent and will probably last awhile. I was one of the unlucky ones that didn't get the premium bcg. But the rifle still functions flawlessly with no misfires or jams what so ever so I can't say anything negative about this kit. Go ahead and get it if you are looking at this kit you won't be disappointed. About to go ahead and order the rifle length premium kit too since this one has been a pleasure.

Great parts for a great price
Good overall kit. Best part is that it has the fn barrel. The rest of the kit is just plain mil-spec parts. Good price on what you get. Gives you everything you need and nothing that you don’t . Very pleased with my purchase

PSA and their front sight.
great barrel, great parts to build my ar. Problem was the F sight was about 3 degrees off center. Didn't matter to me because was going to put a free float on it. However PSA needs to work on this.

Excellent Deal
Only reason for not 5 Stars is it didn’t have the Premium BCG.
Luck of the draw but still a great buy.
