Can this be shipped to a PO Box?
Don S on May 23, 2018
chambered in .223 will it except the 5.56 round ?
george n on Jun 16, 2018
BEST ANSWER: It's the .223 Wylde barrel which will accept both .223 and 5.56. I've ran about 100 rounds of .223 and about 300 rounds of 5.56 through mine no problem
What kind of rifling does it have? Button rifling?
Dennis M on Apr 28, 2018
BEST ANSWER: I believe it is button rifled, but only the mfg would know for sure.
Is this barrel stainless steel?
Singh on Jun 13, 2018
BEST ANSWER: Yes, it is. I have also found it to be VERY ACCURATE,with some of my reloads shooting sub moa out to 200 yds
How does a fore end grip attach to the bottom of the hand guard ?
James Z on Jun 19, 2018
BEST ANSWER: I got a MOE picatinney Rail and mounted that to the bottom. You will need to put it far enough back to where you can get it past the gas block but it is still far enough for what you are looking to do.
Does psa make the barrel?
Dennis M on Apr 28, 2018
BEST ANSWER: Yes they manufacture their own barrels unless otherwise stated. For example FN makes most of the Hammer Forged barrels that they use.
How is steel ammo work?
Singh on Jun 16, 2018
BEST ANSWER: Most ARs are finicky with steel cased ammo.

Just get it!
This is one awesome upper! I paired it with a PSA MOE EPT lower and couldn’t be happier with the results. Rifle is very accurate and is a blast to shoot. Quality is top notch.

Quality product and fast shipping. I’m very pleased with my recent builds. Great job guys!
Very impressed with the stainless FN barrel and N/B BCG provided with .223 Wylde upper. Another quality item from PSA. Shipping was extremely fast.

Does not like all ammo....
I am now shooting federal hollowpoint 55 and getting 1” groups. There is probably better ammunition that will make the gun shoot better but thus far I am really happy with it

Nice looking AR based sporting rifle
Nicely finished PSA upper & lower rifle. Had some function problems at first trial, with ejection problems causing incoming rounds and fired brass jamming together in the receiver. After watching several videos, I decided that the extractor was losing control of the empty brass as it was being flipped outward by the ejector pin. I replaced the stock extractor spring (which came without the Crane Viton o-ring) with a stiffer spring from Bravo Company (still not using their provided o- ring) and went back to the range. This time it fired 100 rounds of 55 grain American Eagle with zero malfunctions, so that fix seemed to have solved the problem.

The upper seems properly gassed, with brass ejecting at 4 o’clock angle consistently and minimal recoil. The barrel fires a very close group at 75 yards when you hold it on target. I polished the mil-spec stock PSA trigger and sear with Simichrome and replaced the trigger and hammer springs with lighter ones, resulting in a crisp, light, smooth and inexpensive trigger. This rifle will primarily be used for target shooting and plinking, sometimes with a .22LR conversion bolt. I love the way it looks and shoots and readily accepts inexpensive accessories on the M-lok barrel guard. If you are looking for a moderately priced, blemish-free rifle, without the “reamed from billet” overhead premium, you probably can’t do much better than this one. Just add an o-ring or a stiffer extractor spring and you will be good to go.

Great Upper!!
I ordered this a few days ago and couldn’t be happier. This is the real deal. It shoots Moa all day long with good ammo. Haven’t tried many brands of ammo but Hornady black ammo in 62 grain and 75 grain shoots lights out @100 yds.

Would definitely buy again
These are very good, I've been shooting high-power with it, while its a little light for that, it shoots really well. Off the bench I can generally hold MOA even with Walmart ammo.
