Wouldn't the barrel profile be considered a heavy barrel for this upper? (Maryland compliant question)
Hayden O on Apr 21, 2018
I'm waiting for this to come in. However I'd like to buy a quad rail in stead for the plastic, what drop in quad rail will fit this upper?
Brinks on Apr 26, 2018
Us this upper compatible with the .223 rounds?
Chris on Jul 6, 2018
BEST ANSWER: long as the barrel is stamped 5.56 its a matched barrel...if the barrel is stamped .223 its .223 only
Could this upper take a different hand guard?
Chris on Jul 7, 2018
BEST ANSWER: While mid-length handguards (8.5") are not as prevalent as carbine length (7") equivalents, there is nothing unusual about this setup that would prevent a drop-in replacement. There are also a few handguards that call for the triangular hand guard retainer - those will not work here.

If you want to free float it, you'll just need proper tools to remove the delta ring, barrel nut and front sight block.
round or triangle front handguard retaining cap?
EspoMan E on Jun 15, 2018
BEST ANSWER: It’s a triangle retaining cap.
Does the barrel profile stay the same diameter throughout, or is it thinner under the handguards ?
Arthur F on Aug 5, 2018
BEST ANSWER: I have several of these. The A2 profile should be the same under the handguard. The government cut is a smaller diameter under the guards. It is also lighter for field carry. Mine are the same .750 under the guard. HBAR is heavier under the guard.

Nice mid-length upper!
I never bought anything from PSA before. I was a little concerned at first, but went ahead and made the purchase. Let me tell you, I was very surprised with the quality. Way better than what I expected. This is an awesome upper. Glad I bought it. I will definitely buy from PSA again. Thanks!

This upper is great!! It’s as good as you’ll find anywhere else for a lot more money!! Put a flip up rear sight on it and it groups within three inches at 100 yards. I will be ordering more of them.

Very pleased
Excellent fit, nicely done. First 90 rounds through it and no malfunctions. Shipping was quick, no lag time between ordering and shipping. Mated to a PSA lower which I have not yet reviewed as I am still waiting for the fix that was to be shipped from Customer Service.

Worth every penny.
Was pleasantly surprised with the quality of all components. Trigger was nice, all components tight, straight and well-finished. May have been a mistake but received an MPI/HP bolt as well. Couldn’t be happier.

Excellent upper. Would buy again.
Very happy with this upper. I now have 2600 rounds through it with not a single jam. It was taken to a training school where most of those rounds were fired with no cleaning. Seems very solid. I can't say the rifle has seen really hard use, but I haven't been easy on it either. Would absolutely consider PSA again. I see a lot of talk about the PSA cold hammer forged assemblies, and I'm sure they're great, but I'm not sure I'd notice any difference between that and the Freedom assembly.
