Why advertising clearance It's out of stock?
Henry Q on Jun 21, 2018
Is the front sight removable?
Michael M on Jul 30, 2018
BEST ANSWER: The front sight post is also the gas block. So yes, but in order for the rifle to function you'll need a new gas block. Though, if you're asking this question it's best to leave it to a professional gunsmith.
This 5.56 only or will it handle.223?
Larry on Dec 18, 2018
BEST ANSWER: Any chamber/barrel marked 5.56 can generally run .223 with no issues. .223 marked chambers/barrels should not use 5.56, the pressure produced by the cartridge exceeds the pressure that the .223 chamber/barrels are rated for.

What do I need to complete this?
Ajt02 on Dec 9, 2018
BEST ANSWER: It's a complete upper receiver. You will need a fully assembled lower receiver to make it a functioning rifle. You will also need some sort of optic to aim your rifle. At the minimum this would be a rear peep sight. The upper receiver already has a front post sight installed.
what is the attachment clip looking thing on the bottom of the front sight, not the strap ring, the other thing?
Sean P on Jan 18, 2019
BEST ANSWER: That's for the sling But I reccomend getting a single point sling adapter. It will require an armorors wrench you can get one for 20 bucks

Is this barrel shiny blue or parkerized finish? Thanks and have a good day !!!
Sniper on Jan 16, 2019
BEST ANSWER: It is not "blue" or shiny. Couldn't tell you if it's actually "parkerized" or not, but it is black and non-reflective.....Cliff
Is the barrel also HP/MPI?
John D on Feb 18, 2019
BEST ANSWER: These barrels are not MPI or hammer forged machine gun steel. They are NOT chrome lined either. PSA makes and sells uppers with the higher quality barrels and will state what they are in the captions when you open them for the details.

I have built scores of them in both configurations. About the only real advantage of the MPI hammer forged machine gun steel chrome lined barrels are not having to clean them after every outing. If you are just target practicing and such no real need for the top shelf barrels, but it is nice to be able to put them away after a long day at the range without a good cleaning.......Cliff
Does this barrel have vanadium? It says it does in the paragraph but not the listed specs above.
Kelvin K on Jan 15, 2019
BEST ANSWER: I bought one of these, I have been happy with it. I would contact PSA and ask if you are concerned.
Does it come in 300 Blackout ?
Jay M on Dec 6, 2018
BEST ANSWER: There are 300AAC uppers on the site, some that even resemble this one. But this upper is what it is.
The BCG on this upper calls out full auto, my lower receiver is obviously a semi auto, will this be an issue?
Iceman on Dec 3, 2018
BEST ANSWER: No. It will work just fine.
When will these be back in stock?
NickKHecht on Sep 6, 2018

Tommy on Feb 8, 2019

Great lower for s great price
So far I’ve got a bit over 1000 rds thru it and I’ve had zero malfunctions, running just an mbus rear sight I’m getting 11/2 inch groups at 50yds and I open up just a bit more at 100 I’m sure once I add optic of some sort that will tighten up. My eyes are not what they used to be. Seems to be a good solid upper.

I bought my upper and lower in two separate orders as to fit it into my budget. They fit together perfectly, she has not had a single hickup at the range. Thank you P.S.A. for such a quality product at a blue collar price....
