Who makes these barrels? Alot of ppl would like to know how they compare to the fn chf ones
Joshua g on Aug 6, 2018
BEST ANSWER: PSA makes these, so far everything has been outstanding and you will have no issues. Just purchase one and enjoy the quality, and the savings
Can I put optics on this without removing the front sight?
Randall S on Jan 5, 2019
BEST ANSWER: Yes. Your optic mounts to the picatinny rail on the upper receiver. A carry handle or backup rear sight will simply line up with the front sight. Red Dots will either co-witness (the red dot is on the same plane as the front sight post) or it will "lower 1/3 co-witness" (meaning the front sight post will appear at a point 1/3 up in the window of the red dot sight) depending on the sight mount you choose. Same would be for magnified optics. I have a red dot with a lower 1/3 co-witness and when using the sight you don't even notice the front sight post...but it's there should you need your backup iron sight.
What charging handle does it come with...6061 or 7075 ?
Paul E on Jun 18, 2019
Is the bolt full Auto?
Marko on Jul 29, 2019
BEST ANSWER: Yes the bolt carrier is full auto profile.
Is this able to ship to California?
Mikemike on Jul 31, 2019
BEST ANSWER: Not completely positive but I don't believe you can ship it to California. Check with you local police department for find out for sure. You could always call them or contact PSA to find out. help this helps.
Hey, can anyone tell me if the handgaurd cap infront of the gas block is round or triangle shape?
Brett on Jan 7, 2019
Is the barrel free floated?
Daniel D on Jul 31, 2019
BEST ANSWER: no the barrel is not free float . This style of handguard connect to the barrel nut and the other end connects to the a2 front sight post. If you want free float you will need to look for something with a rail in place of the handguard and mount something like a Magpul backup sight to the front.
Will this upper fit on any of the PSA complete AR lowers? Would all I have to do is connect the two and slide the pins in or are they missing some parts?
JTolderon on Jul 29, 2019
BEST ANSWER: You have a few other things to purchase. In this case, you need a complete bolt carrier group, a charging handle and some type of rear sight, be it a red dot, scope, carry handle. And yes, it will fit on any AR lower, but since this is a 10.5" barrel, it has to be on a pistol lower, not a rifle lower unless it's a registered SBR. Put it on an unregistered standard rifle lower and you've committed a felony.-
What are the specifications of the BCG that is included with this upper?
edgar r on Jun 12, 2018
BEST ANSWER: Phosphate M16 bcg with bolt marked MPI. Cycles fine in my pistol build with a standard pistol KAK buffer tube. I was hoping for annitride one but this works problem free. If it works reliably for the military I should be happy with it for my plinker.
What profile is the barrel?
Bryan B on Jul 26, 2019
BEST ANSWER: I think heavy
Does this upper have a heat shield?
Jacob H on Aug 29, 2019
BEST ANSWER: Yes, it has internal heat shields clipped inside of the plastic hand guards. They are easily removable but weigh almost nothing. You can easily fire 3 mags in quick succession without excessive heat build up. I haven’t fired more than that in a short amount of time yet. I’m happy with the purchase.
Is the barrel chrome lined?
Gary D on Aug 5, 2019
BEST ANSWER: It is advertised as a nitride barrel. I am not aware of anybody adding chrome as it would not add anything to the performance of the gun. You do one or the other, not both.
will this fit on my PSA Freedom m-4 lower?
sbike on Jul 26, 2019

Yes, it will fit all of our milspec AR15 lowers.

Bernard P on Apr 13, 2019
BEST ANSWER: Standard 1/2"x28.
Is the gas block pinned, or does it use set screws?
Steve on Aug 31, 2019
BEST ANSWER: Pinned; no set screws
Would this go better with Shockwave pistol or MOE magpul lower? I have a Colt SP1 but this is my first build. Thanks for any info.
Gonzo on Jul 26, 2019
BEST ANSWER: I would go with the Shockwave. I have built a few, and enjoy them.
Caution, be sure you are using pistol components. Do not mix rifle and pistol parts. It is either a legal pistol or a legal rifle. Building is fun, but stay legal, and have fun.
What is the profile of the barrel underneath the handguard. Is it a lightweight, pencil barrel?
Brian D on Aug 4, 2018
BEST ANSWER: The barrel is the standard non-tapered barrel. I have used four of these uppers and they are very well made and assembled.
What length handgaurd does this use?
Chris A on Aug 22, 2019

This uses a carbine length handguard.

If I replaced the birdcage with XM 177 type would it be long enough to be legal on a AR lower?
Buddy on Aug 14, 2019
BEST ANSWER: No it would not! for a 10.5 barrel you would need at least a 6.5” muzzle device and it would have to be permanently attached if running it on a rifle lower. You can legally put it on a pistol “depending the state”
What do I need to replace the front sight? I want to either put a rail on or a flip up. Also going with an MOE guard.
Chris S on Jul 29, 2019
BEST ANSWER: In order to change the front sight you basically pinch two pins out (they only go one way)and then put a different gas block on and push the two pins back in. I would just buy the upper already configured like you want, PSA has one of every config.
Is the barrel made of 4150 steel?
John I on Aug 30, 2018
Is barrel made by FN?
Joe G on Jun 25, 2018
Is there any way to put a hand stop at the end of the foregrip?
Temposhot on Aug 21, 2019
BEST ANSWER: I believe you can get a rail section that will mount to the handguard, then you can.

Great Price Great Quality
Got the upper and a PSA bolt for a budget pistol build. It short, it ran 100% and shot very well. Gobbled up M855, M193 and crap steel case w/o a burp. First time I have gone with a non chrome lined barrel. I noticed no difference. And the finish on the upper is "thick", dark and Mil Spec looking.

Very impressed with everything PSA builds
Ordered this for a at pistol lower. Didn't come oiled but still shot beautifully. Was still extremely clean after shooting about 100 rounds through it (after I oiled her up). All my PSA iron sights are always way over to the left but I put the $50 mock acog on it from Amazon and it's just fine.

Sloppy fit
I got this upper and fit it to the complete Shockwave MOE lower. Was vary happy with the quality VS price of both pieces. The fit however is a little sloppy. Over all quite happy with the pistol and if it had been a tighter fit I would have given it 5 stars easily.
Looks great but the fit is not tight and a bit sloppy.

Cool little upper kit
Built mine with a PSA M4 lower and a SBA3, and I just love the way it looks and shoots!

Great Little Upper
I have nothing bad to say about this upper. It has been a ton of fun to shoot on my sbr lower and pistol lower. A little overgassed as is normal for most mass-market uppers. Use an H or H2 buffer and it's good. Accuracy is good for ringing steel 25-200 yards. I can't give a group size because I have never put an optic on it and my eyes are not up to benchrest shooting with irons.
With Magpul MOE SL handguard and UTG rear sight on a PSA pistol lower.
With carry handle sight on sbr lower.

Great deal for the price.
Very satisfied overall with this upper. Came well oiled out of the box. Cleaned and re-lubed after first 10 shots and running butter smooth since. Front sight wasn't perfectly centered but it didn't take much adjustment to get windage corrected. Not perfect, but absolutely functional, serviceable, and most of all affordable.

Very impressed
This was my first Palmetto and I couldn't be more impressed. The service I received was second to none and the upper came in super quick with the lower being shipped to my FFL. I opted to go with the nitride finish so both upper and lower match perfectly. Shotting was a blast! I'm definitely going to be a repeat customer!
Very impressed
