Will this upper work with a carbine length spring and buffer?
vnamvet on Jun 21, 2018
BEST ANSWER: Any milspec spring will work on 223 wyld. I use the same power for my 6.5 Grendel and 556 nato rounds
can I get a 6.5 Grendel bolt carrier with this upper?
Jack H on Jun 1, 2018
Will it fire 5.56 ammo?
Jochua N on Jan 11, 2019
BEST ANSWER: Yes, a .223 Wylde chambered barrel is designed to accurately fire 5.56 NATO and .223 Remington ammunition.
Will my bcg from bushmaster work in this upper?
Patrick C on Jun 27, 2018
BEST ANSWER: If its one of Bushmaster's old BCGs then its mil-spec and will work. The Palmetto Uppers are mil-spec so any compliant BCG will work.
I have BCGs from several different sources, and so far everyone of them has worked in this upper.
Hope this helps.
Will this upper work on my bushmaster m4 lower?
Patrick C on Jun 27, 2018
BEST ANSWER: Yes as long as your bushmaster is an AR 15 platform!
Is this head spaced from PSA?
My N on May 21, 2019
BEST ANSWER: If it comes with a BCG the head spaced is checked, if you use a BGC from another weapon you will need to have the head spaced checked.
I'm looking to add some side attachments to this upper. Any suggestions? Is this compatible with key-mod railings?
Isaiah on Dec 27, 2018
BEST ANSWER: No it has a M LOK forend. That is compatible with the M LOK accessories. I actually prefer M LOK over KeyMod though. There are accessories available just about everywhere for M LOK systems. If you prefer KeyMod there are still plenty of places that sell KeyMod forends and accessories though.
How is A2 attached on this barrel?
bonegunner on Sep 7, 2018
BEST ANSWER: Muzzle is threaded 1/2-28..
What kind of accuracy can I expect compared to a mil-spec .556 upper?
Doug L on Oct 14, 2018
BEST ANSWER: I only have a sample of 1 but mine is less then half the size if an average mill-spec. With MK262 ammo I am getting well under 1 moa probably closer to 0.5 moa.
Will this work with my panther dpms?
Chuckgreen on Aug 15, 2018
BEST ANSWER: I've used PSA uppers with Anderson, Aero, and Spikes lowers and haven't had a problem. As long as it's an in spec lower should be no problem. If it is I'm sure PSA will take it back. Great company!
Who makes the barrel?
Stevo on Jul 28, 2018
BEST ANSWER: I have heard that FN manufacture is not true unless the barrel is described as cold hammer forged, which this is not
Does this upper have the bump at the gas block? If so what model is it that will eliminate that?
James S on Oct 12, 2018
BEST ANSWER: No bump on mine ? Functions great.

Excellent. Blown away by the performace and the price point.
Sub MOA with hornady 55 gr varmint and 75 gr hornady bthp match. 55 gr American Eagle and Frontier have no problems ringing a 12" plate at 330 yards.
Dressed up.
100 yard group.

Fantastic Deal. Makes other guys with DDM4's angry
I bought this upper for my first AR after a lot of research, and I am very pleased with it. It is accurate, lightweight, and cool looking. I have seen some guys get 1" MOA out of it. What more do I need? My SPR/Practical rifle is complete!

Awesome upper
I put this on the 7791514 lower. The fit and finish of the two are excellent. This upper is very accurate compared to my 10.5” PSA upper. I know the barrel length is partly why but the 223 Wylde is pretty nice too.

Very good for the Price
Very lightweight.

Assembled with a PSA lower and MOE lower kit. Added a Geissle G2S-E and a Primary Arms ACSS 1-8.

After about 40 rounds of break in period I was able to throw some 1 MOA groups at 100 yards using Hornady BLACK 75gr BTHP. Who knows, this could get better as I feed this beast some different weight ammo...

Only complaint is that the mlok handguard is very skinny...this may not seem like an issue but, when attempting to mount anything in the two mlok slots closest to the muzzle end, the mlok screws will make contact with the bottom of the gas block. Essentially, nothing can be mounted there. In my case I was trying to mount a picitinny rail section so I could QD mount a bipod. Ended up having to go behind the gas block.

Competitive price, good quality, good service, will buy from PSA again and again!
I really like the PSA products, competitive price and good quality. Stainless barrels are well machined and shoot sub MOA if broke in correctly, add a little Cerekote, a good trigger and good furniture and you got a great looking and shooting rifle!
