Sandy B on May 23, 2018
BEST ANSWER: If your lower is made to "milspec" sizes, and most of them are, then the upper should work just fine. I've used it on a milspec homemade.lower as well as a spikes lower with no problems.

Is the 16 inch barrel legal I thought it was supposed to be 18inches?
Ray T on Mar 19, 2019

Does the handguard come off to expose just the rails?
Dario P on Jan 9, 2019

BEST ANSWER: No sir, the hand guard is by magpul and will only accept that brand of attachments.

2 Questions: 1) Will this work with .223 rounds instead of 5.56? 2) Can you put a foregrip on the handguard?
Ronnie B on Jul 10, 2018
BEST ANSWER: Since it is chambered for the military 5.56 it will be fine for the .223 with some loss of pressure. The converse is not OK

How do you know if it is a drop in barrel or free floating?
Bill F on Jan 25, 2019
BEST ANSWER: The term "Drop in" typically refers to a part, like a barrel, that is easily changed or replaced with out any gunsmithing or fitting. The term "free floating" refers to a barrel that doesn't have anything touching or bearing on it.

In this case, this upper assembly is a "drop in." It should fit most standard AR-15 lower receivers. The barrel on this assembly, though, is not "free floating."

Favorite rifle in my safe
I was just looking to do a budget build because the New Year bug bit, so I picked up one of these "blem" kits. I have inspected every mm of the thing and can't figure out what/where the blem is! It's beautiful, matched my Aero Precision lower like a glove and turned out to be my favorite rifle after running approx 650 rounds through it. She shoots 1" groups at 90 meters (may do better with a better shooter) and hasn't suffered a single F2F, FTE, even with cheap ammo, polymer-coated stuff, steel, it doesn't matter, this thing just runs. I can't wait to do another build!
Lighting is rough, pics don't do it justice.

Extremely pleased with this upper!
The upper is perfect. I installed in on Ruger Elite lower. This thing groups perfectly! Palmetto State Armory IS my favorite AR provider. This carbine complements my Freedom AR I bought several years ago. PSA sells great rifles and components for a very fair price and the quality is top notch.

Great experience, fast shipping, great quality right out of the box. Just buy it!
Really impressed with this upper out of the box. I paired it with a pretty basic PSA lower. I ended up upgrading the lower grip and stock to Magpul MOE furniture(just buy it already on the lower, it's cheaper that way). After 600 rounds and 2 cleanings, this has been a great setup. The MBUS rear sight is very nice with 2 different distance peeps. I consistently shoot 2-3 inch groups at 50-75 yards standing with the irons. I'd say that for most people, the upper is more accurate than you are. If you're even considering buying this, just do it. The Magpul handguard is very comfortable and the sights are good. Elevation was about 2 inches low out of the box. Nothing a front sight adjustment couldn't fix. I'm so impressed with PSA that i want to do an M16 clone and one of their AK pattern rifles in the near future. I would not hesitate to buy anything from them, whether it's their brand or not.
50 yard group, standing, iron sights

Excellent Upper as always
Excellent upper just like every one I’ve purchased from PSA in the past. Great fit and finish and doesn’t complain no matter what ammo I use. Perfect to start a build with and will be buying more in the future.
