Is this a complete upper assembly or are additional parts needed?
Jim D. on Jul 3, 2018
BEST ANSWER: these are complete upper halves.
only a rear sight or optic is needed.
What's the total length of this upper receiver?
Death2Darkness on Nov 25, 2018
BEST ANSWER: Twice the distance from the center to an end. Same as every other standard 16" carbine upper on the market.
Does this upper have a round gaurd stop?
TurnBuckle on Dec 11, 2018
BEST ANSWER: yes, carbine length gas system uppers come with round end caps
How would you place an optic on this with the front sight sticking out? I’m interested in putting on a scope 3x32 but thinking it will interfere? Will you need high mount rings?
Alex J on Mar 19, 2019
BEST ANSWER: It actually won’t interfere with your sight picture as the 3x is strong enough and the FSP is close enough to almost completely blur out.
I put a 1x4 FFP scope on one like that and at 1x it was just a blur in the sight picture.
At 4x it was gone. I have the Nikon 3x32 on a Primary Arms Mount and it works great.
If you find you don’t like the look you can remove the fixed front sight and replace it with a railed gas block and keep the handguard set up.
I did this on a PSA Freedom upper.
Will the BCG and charging handle from the 16" upper shown here be usable in the 20" of this listing?

Is this assembled out of the box or do I need assemble it myself?
Yeeet56 on Jul 28, 2019
is this barrel stamped with “freedom” somewhere? I can’t find it
Kendall E on Apr 4, 2019
Is this all I need plus the Freedom lower I've already purchased to complete my build?
CHARLES H on Jul 23, 2019
BEST ANSWER: That would be correct. Never had any issues with PSA products. Just keep them cleaned and oiled.
Is the muzzle device removable?
Nicholas H on Dec 21, 2018
BEST ANSWER: Yes, the muzzle device is attached with a standard 1/2” x 28 thread. It is removable.
Do I need a ffl to purchase it?
Bull dog on Mar 18, 2019
BEST ANSWER: Nope. It can be shipped right to your house. Only a lower receiver has to be shipped to an FFL.
Can this handguard be replaced?
Irish on Jul 29, 2019
BEST ANSWER: This hand guard can be replaced with any drop in carbine length hand guard. A free float hand guard can also be swapped in its place but the front sight block would have to be removed and replaced with a different gas block.
Is this barrel stamped with 5.56?
Ricky 9 on May 10, 2019
BEST ANSWER: Usually the Freedom series uppers have the markings done via pad-printing with indelible ink rather than being metal stamped as you might expect. Yes, the printing does say 5.56 NATO.
What size hand guard would I need for this upper?
William on Nov 30, 2018
BEST ANSWER: Any standard Carbine length Handguard will work with this upper.
Im new to AR's, what kind of accuracy can i expect out of this at 100 yards?
Anthony J on Jan 4, 2019
BEST ANSWER: Anthony, this upper will be more than adequate for 100yd ranges. Open iron sights should put you in 3-4MOA. Add a magnified optic or precision red-dot and you can likely tighten that to 2MOA. Typically a rifle will outshoot the user in most cases. Happy shooting.
Anybody have problems with Anderson lowers with these uppers?
WESLEY B on Aug 10, 2019
BEST ANSWER: The lower and upper combination will never matter if they are built correctly. Anderson is a great lower I have 2. In my opinion tho the lower isn’t gonna matter it’s just paying for the brand.
Are the Serial numbers on the lower only?
Shawn F on Jul 29, 2019
BEST ANSWER: Yes. Only the lower has a serial number.
Does it have feed ramps?
Chad W on Jul 23, 2019

Yes, it has M4 feed ramps.

Anyone run this on an Anderson aluminum lower? Someone mentioned in the reviews that it won't work on some lowers, want to make sure before "pulling the trigger" :).
Astro D on Jul 25, 2019

It may work fine with other manufacturers lowers, we can only guarantee that it will work with our lower receiver.

Will this fit. Rock River Arms lower? Or a Core 15 lower?
Robert C on Aug 3, 2019
BEST ANSWER: Robert, it will in fact fit. These lowers and uppers are forged/machined using the same specs. Some uppers and lowers may have very small differences but it will in fact fit. These uppers from PSA are a very good deal. All mine fit fine with different lowers, function well too.
Can you get this in the drab green ?
James C on Aug 8, 2019
BEST ANSWER: Yes. The hand guard is the only piece that is gray. You can order it from psa in different colors and styles. Hope this helps.

Ok, but expected better from PSA.
This is the first upper I've received from PSA that I'm sending back. It shipped with the wrong bolt carrier and a canted front sight. I'm sure they'll make it right just kind of annoyed since they usually get it right the first time and now I have to wait longer to finish this build. It was on Clearance so maybe that had something to do with it.

Another Fine Product From PSA
Fit and finish is outstanding. Changed the hand guards to MagPul MOE M-LOK, hand guards, but I do that with all AR uppers. This is the fourth upper that I've bought from PSA and I find their products quite satisfactory and will probably continue to purchase their products in the future. Would certainly recommend this product to others.

Great as usual
This my second upper. As usual the fit and finish are
perfect. Both shoot dead on and never have had a malfunction.
I can only afford items when on sale and am a return customer.
Thanks for putting out great products. Bill.

Simple Mil-Spec AR That Does What It's Supposed To Do!
Clean and simple Mil-Spec design and PSA quality. I check this using a micrometer and it matched two other brand name ARs. Why pay more unless you are buying for status, and these are gaining a reputation for quality. I know a number of LE officers who own PSA weapons and all are pleased.

Wow! Great Upper!
I'm usually stingy when it comes to giving out praise but I am really impressed by my PSA 16" NATO M4 Nitride Freedom Upper!! And it was incredibly affordable. I would definitely buy from PSA again and recommend this upper to anyone considering a purchase as a replacement or if building your own AR . Thanks PSA for a great product!
