Can the flash hider be removed? I'm in CA and that's a no no. Only compensator or muzzle brake. Booo
Henry on Jun 6, 2018
BEST ANSWER: I have not removed it, but I believe that I could. It is not welded to the barrels, and it is clearly not part of the original drilling / forcing that made the barrel. So I think you'd be good to swap it out. I feel for you in Cali though ... I'm from there as well, but was moved (by Uncle Sam) to Kansas, and have truly enjoyed the freedom. I will never go back.
Does this barrel have the nitride lining?
Dhammers on Jun 4, 2018
BEST ANSWER: Yes but is not chrome plated so do clean often.
will this work with an Aero Precision M4E1 lower receiver?
keyguy707 on May 19, 2018
BEST ANSWER: Yes because Aero precision makes lowers and uppers for PSA
Is this receiver marked with a PSA logo or is it unmarked?
M A on May 15, 2018
BEST ANSWER: There is no PSA logo or marking except on the top of the barrel forward of the A-Frame front sight post that reads: "5.56 NATO 1/7 FREEDOM"

Triangle Handguard Cap?
Be aware, these have triangle handguard caps. I ordered about $300 worth drop in qual rail handguards that were for round handguard caps... I've never received a PSA rifle with a triangle handguard cap and didn't see anything in the description mentioning this came with it... Still a great upper, but I wish this was noted.

Excellent Upper Reciever
She was a a bit rough when I first received her because of the patented metal PSA uses. After a few mags she fired in tight groups with little adjust needed right out of the both. Very impressive to get a mail order upper receiver that only required 2 adjustments (1-left 2 up). The roughness I referred to has to do with the bolt carrier group needed to be broken in. The friction plates are smoothed out entirely until the complete AR has been used with at least 30-60 rounds. I will jam with cheap mags so I stick to the polymer upper end ones. Small amount lubrication is suggested on the friction points especially during the break in period. IMPORTANT use bore solvent to get rid of any packing oils/grease from the barrel entirely. Without doing that your BZO will always be off as it warps the grooves. Excellent rifle and excellent rifles need care.

Accurate, lightweight, reliable
I bought this to build my wife an AR, and I want one for myself now too. I changed the hand guard to an OD green of the same model for her preference only, but that is the only change. This upper is quite accurate. I've routinely managed sub 1.5-inch groups at 100 yards with a red dot (Vortex Sparc) and IMI 62gr ammunition. Federal 55gr seems just as accurate, though I haven't tested as much yet. The upper has not had a single issue cycling steel cased ammunition (Tula) either. The barrel appears to be a thick profile, which made me assume it'd be a little heavy ... but with the Red Dot optic installed, the weapon is easy to carry for hours at a time. It's definitely NOT heavy! My build worked great with the following components: This upper (duh), Vortex Sparc optic, Anderson stripped lower, BCM PNT Trigger, AR-Stoner parts kit and buffer kit, Magpul MOE collapsible stock, Magpul grip. Buy this upper! (PS, it looks absolutely sick in OD Green too.)
100 yard, IMI 62 Gr, no wind
Looks great in OD Green!
