With the obvious exceptions of the finish and laser engraved logo does the bolt carrier have the same functional specs as the PALMETTO STATE ARMORY 5.56 PREMIUM FULL AUTO BOLT CARRIER GROUP - 8779?

Is this an FN barrel and what's the 100 yard accuracy?
Barry B on Jan 23, 2019
BEST ANSWER: I built may dad his first AR with this upper for fathers day. After a proper break in and several rifling scrubs, we got it stacking rounds @100 and shot a 3" group @600. This is a phenomenal upper! Ammo used was boxed Norma Tac .223 55gr. Black and red box. I have pics and video of said performance @ CMP Talledega.
is gas block pinned?
Kevin P on Dec 2, 2018
BEST ANSWER: No, it was not ... I have found that I have never needed a pinned GB. I usually just dimple the marks on the barrel and torque the set screws proper.

dallas A on Dec 23, 2018

Is the psa snek 15 stripped lower compatible with this, and if so can I use the standard psa lower kit with it?
infoFUNK i on Jan 25, 2019

GRANT S on Jul 14, 2019

What advantages does the Nickle Boron BCG offer? Thanks
Fatelvis on Jun 30, 2019
BEST ANSWER: Nickle Boron offers increased reliability thanks to lower friction and an easier cleanup after firing.
Can this barrel fire 5.56 mm ammo?
Mike L on Jul 14, 2019
BEST ANSWER: 223 can be fired in 556 barrels. 556 generally should not be fired in 223 barrels. 223 Wylde is a compromise that fires both 223 and 556 quite well. Hope this helps. 🇺🇸
Can someone please compare/contrast nitride vs stainless barrels? Is it true that nitride are generally harder thus giving it a longer life and stainless will be more accurate?
James C on Jul 6, 2019
BEST ANSWER: This is a plain stainless barrel. You can nitride stainless and you can nitride carbon steel. Nitriding will increase the barrel's useful life. Both can be made to the same level of accuracy. This barrel should last at least 6000 rounds with out of the box accuracy. Probably double that if you take care of it (no mag dumps). You can replace the barrel for less than 200.00 if you ever get to the point that you wear this one out.
Any idea of the barrel weight..?
Doug E on Jul 5, 2019
BEST ANSWER: More than pencil. Less than H-bar.Two ounces more than the 16 inch types.
Is the gas block made of quality steel or an aluminum of some kind?
Huggy on May 22, 2019
BEST ANSWER: The gas block is good quality I really enjoy mine. No problems.

Great upper!
My experience so far has been fantastic!
The upper shipped fast! (I also ordered the PSA EPT MOE Lower Build Kit - 778097)
The cost to quality are outstanding!
The fit and finish on my upper are really good. (I'll add pictures soon)
- The nickel Boron BCG looks great(no marks or machining marks, good staking).
- The Free-float hand guard is simple, light, slim and well thought out.
- The barrel is clean, well marked(as in caliber,twist rate, etc.)

I've fired 200 rds so far, no malfunctions, only one type of ammunition 5.56 55gr.(W white box).

the accuracy looks good(I only have access to a 25 yd indoor range currently)

My only 2 cons:
- I found one tiny little blem on the free-float rail(doesn't effect functionality)
- No weight listed on product page

I'll update the review once I get more rounds through this upper.

Well worth the money
Well my experience might be different then others but here is my experience. I placed the order easy enough and did my time waiting and when I got it the upper receiver had 3 dents in the side of it . My fancy bolt carrier was rubbing on the dent . So I called several times to figure out the Process to return the item and they were very helpful in doing anything in there power to make the return process easy . Then I got my new one a couple weeks later . Although there were marks in the same place as the one I sent back , but it wasn’t dented this time . I’m very happy with the whole gun and I would recommend this idem

Awesome
Put about 1500 rounds downrange and this is a great shooting rifle. I really like the stainless barrel and nickel BCG. No malfunctions so far. Only issue was hand guard screws came loose, but no big deal. Highly recommend

I like it 😋
Would recommend for a normal build. Seems well built, quality parts and reasonably accurate. No problems so far (aprox.500 rounds).

Sub MOA
It match up perfectly with a Bushmaster AR15 lower. The upper met my goal of a budget varmint gun. It is producing 0.8" groups at 100 yards with hand loaded 65 gr GK SPBT with 25 gr Varget. The only minor glitch was failure to cycle Remington 55 gr 223 factory ammo, so I wasted the money for a box of 100. It shoots and cycles Winchester 55 gr 223 factory ammo okay. I shoot almost exclusively hand loads so I am not concerned the issue with Remington ammo. I would recommend.
