What is the weight in pounds?

PSA 16" Mid-Length 5.56 NATO 1/7 Phosphate Classic Upper Without BCG-CH
BEST ANSWER: Nitride is better its the newest and actually bonds to the metal on a molecular lever. The phosphate is good and something the miltary uses. The nitride wears better and better looking, eaiser to clean, and superior in many ways. I have both and I wish it was on all of them
Is this upper mil spec?
Ashley P on May 28, 2018
BEST ANSWER: Technically no, but that's ok. Mil spec would be a chrome lined barrel, but this has a nitride finish. But the nitride is just fine and has shown to be just as good at protecting as chrome lining, and plus chrome lining will reduce your accuracy. The steel is up to spec, and PSA builds with a lot of quality.
What’s the length of the hand guards?
Edddd on May 30, 2018
BEST ANSWER: Mid-length.
Will this work with an a2 buffer?
Jcrose on Jun 3, 2018
BEST ANSWER: Yes
I know this upper assembly has a triangle end cap, could I in the future take the fore arm guard off and put a longer free float fore arm gaurd on?
Ryan C on Feb 26, 2019
BEST ANSWER: You can change the handguard, but not a free float handrail. Unless you want to change out the entire gas block and gas tube. Magpul makes a real nice handguard for mid length gas systems.
is this a heavy barrel?
endfoulks on May 30, 2018
BEST ANSWER: It is not a bull barrel but it is heavier than the standard M 4 barrel .
I have a functional PSA AR-15 with a 10 and a half inch barrel. Can I just swap the barrels?
Johnny rk on Feb 21, 2019
BEST ANSWER: There are legal implications when you go from a short barrel to a long barrel, or vice versa. As long as you're aware of those and how to follow the law, you should have no problem swapping out a barrel in one upper for a different barrel. Just ensure you have the right size gas block.
What vertical grip fits this model ?
Antoine1229 on Aug 9, 2018
BEST ANSWER: In order to add a vertical grip, you would have to change out the hand guard with a rail system or guard that has provisions to mount a vertical fore-grip. As it is sent to you it comes with standard heat shield grips that are not provisioned for it.
Is the A2 flash hider pinned and welded or can it be easily removed?
Jimbo on Apr 30, 2019
BEST ANSWER: The one I received was easily removed with an armors wrench.
This is a 4150 cmv barrel correct? It says it is in the upper portion but on the description below it just says CMV barrel.
Cowboys1 on Aug 29, 2018
BEST ANSWER: The entire barrel is made from 4150v. Chrome-Moly Vanadium steel. It has a Melonite finish to it just as the description says unless there was a change since last October. The upper receiver is 7075-T6 forged aluminum alloy, hard coat anodized all mil spec part.
can i put a bayonet on this?
meow M on Jul 21, 2019
BEST ANSWER: Yes, I believe an M-9 will fit.
Is the headspace already checked on these and ready to go? I'm using with a PSA bolt carrier group that I purchased separately.
Adam S on Jan 10, 2019
BEST ANSWER: Go to the "Contact Us" link at the bottom of every page and ask PSA directly. 99% of the people here who read your questions wouldn't know...
This upper just arrived this week, I’m very happy with the product, I’m kicking myself for not getting the Magpul upgrade, that’s where my question comes in, does anyone know exactly which Magpul MOE M-lock handguard it is that fits this upper? It does have the triangle under the front sight

PSA 16
PSA 16" Mid-length 5.56 NATO 1:7 Nitride Freedom Upper - with BCG and CH - 507281
BEST ANSWER: Their mid-length MOE M-LOK handguard should fit, as long as it's not the SL ("slim line") version. According to Magpul's website, the SL requires a round cap but the standard, thicker MOE handguard is compatible with both types of front cap.
How would one fix a canted upper, besides sending it back?
Polite SOB on Jun 16, 2018

Great value for a quality upper!
Great value for a quality upper! I picked these up several times, when in stock. I then took off the handguard and put magpul mlok midlength handguards on. I now have one in every color. I definitely recommend this upper.

Good fit
I have tried it on different lowers and it fits well. It looks good and functions fine. I have not fired the upper other than to test for function. I see no problems ...

Good quality, excellent value.
Been too hot lately to take it out to shoot but it looks nice. Added a psa carry handle which is equally nice, and an aero bcg. Just haven’t shot it yet. I have another one I picked up a few years back that shoots perfectly well.

I have had this upper assembly for about two years. I have put roughly 5,000 + rounds through it and have never had a malfunction or stoppage. You do get what you pay for but when it comes to these Freedom line uppers, you do get a decent bang for your buck. These are not precision based by any standard but they do provide MOA to sub MOA accuracy depending on Shooters skill, ammunition Etc. I will post two pictures of my rifles set up. It is mainly used as a backup rifle for someone else at the range or an extra plinking rifle for fun.

Awesome as always
This is my 4th mid length upper from Palmetto State Armory. I can only say that their quality just gets better with age. If you are on the fence about these guys, don't be. Their quality is miles beyond what their prices might suggest to you.

Great Mid length Upoer
This is a great upper. I like my S&W carbine length but mid length is a nice change and this one is beautifully made.

Great functioning upper!
This was my first AR build and second AR overall. This fit with an Aero lower fantastically. Only complaint which is purely cosmetic the upper receiver came with somewhat noticeable flaws in the finish. Which personally doesn’t really matter to me as long as it functions!
April 7, 2019
great bang for the buck
The most accurate AR that I own. Shoots 62 grn. really well and 55 grn. pretty good. It prefers the 62.
Fit and finish were very good. Attached to my 80% lower nice and snug.
The price was really good!
