Wanting to swap out my 16" factory barreled upper on my Smith & Wesson M & P Sport 2, will this work?
Tad J on Aug 2, 2018
BEST ANSWER: Swapping out barrels on the AR platform is pretty standard for a lot of builders. Just need to make sure you have the right length gas tube. And with this setup you will have to get a free float rail system.
Is the flash hider removable? I need to be Cali legal.

Outstanding Value for the Money
I've only put about 50 rounds through this upper so far, but I am more than pleased. I used the BCG, charging handle, and lower from my Ruger AR556, and everything functioned flawlessly.

I ran 55gr Wolf Gold, Hornady Black 75gr Match, and Magtech 77gr OTM through it, and it handled each without issue. I only have access to a 25 yard indoor range, which is a ridiculously short range for an AR, but I was very pleased with the groupings I achieved.

I mounted a Primary Arms 1-6x ACSS scope, and the combination is a winner. The 77gr Magtech had the tightest groups for me.

The one and only issue I would note about this upper, and it isn't a complaint, just an observation, is the finish. It feels almost like a powder coating, and it picks up rubs and scuffs very easily. I'm not concerned with appearances, so that is not a concern, but it is something to note.

You can spend more JUST for the free float handguards from some manufacturers than this entire upper costs. You cannot beat this deal!

Very Accurate
This upper is a great value if you’re looking to build an SPR style or pseudo precision rig. The fit and finish are excellent, and the barrel has great accuracy potential. I’ve paired this upper with a fixed MOE rifle stock lower with BCM nickel Teflon FCG. With a Vortex Diamondback Tactical on top, normal 55gr plinking ammo gets about 2-2.5 MOA. This upper definitely likes the heavier match stuff. My first 3 shot group with Hornady Steel Match 75gr was .87” @ 100 yds off of a poor rest. I haven’t run it hard, but I’ve had no malfunctions in the 200 or so rounds down the pipe.

Awesome Upper for the money!
Got this upper recently and absolutely love it. Didn't have any issue what so ever when I took it to the range. It ran 90 rounds of 55gr. xm193 ball just like a charm. Fit and finish is perfect, and it came right in time. Thank you PSA for making such an awesome upper!

PSA comes through again
Put together my first AR on a shoestring, using a PSA rifle kit and a locally sourced stripped lower. Went together quick and easy, and worked flawlessly from the first trigger pull. Decided I wanted to upgrade, and chose this upper, and I couldn't be happier. Fit and finish is excellent, balance is very good, and like my first rifle, this thing just works. The main reason for upgrading was accuracy, and this didn't disappoint, with the right ammo, I consistently get sub-MOA 5 shot groups, and that's factory ammo, I haven't started load work up yet.

Almost forgot, the most frequent complaint I see about PSA is slow shipping, I've had around half a dozen transactions with them in the last year, every order has arrived in less than a week, and I'm on the opposite side of the country, AND in the boondocks! Will definitely continue to do business with them.

Great value for the price
Put this upper on a spikes lower, purchased a PSA bolt and BCM gun fighter charge handle. Changed out the flash hider for a JP brake and went to the range. Dailed the gun in from a rest at 50 yards with a 55 gr factory load. After the 1st 20 rounds i cleaned the barrel and wow, the groups really tightened up. 100 yard shots were .5 moa with off the shelf Independence AR-556. Cant wait to try some of my 55 gr. hand loads.

Received this upper, intact and packaged well !! Once assembled, I took it to a range for a "live fire & function" test. No optics yet... but it functioned, and cycled 5 different brands of 5.56 ---- even some steel cased ammo. NO issues at all.

Good upper
The upper is very accurate. I used an Aero precision lower for this build and the fit was perfect. No wobble.
