Best ammo to use with this upper?
John C on Jun 11, 2018
From everything I have read online about the 223 Wylde barrel I should be able to run 5.56 but I have seen a few 223 Wylde barrels online that state “not recommended for use with 5.56”.
Can I run 5.56 NATO through the barrel without issue?
Brandt B on Apr 23, 2018
BEST ANSWER: .223Rem and Nato 5.56 work fine in a 223 Wylde barrel. Some .223Rem barrel manufacturers warn against shooting 5.56 because it is hotter. Almost all AR barrels are chambered for 5.56 or 223 Wylde which will handle both great.
Is this a ptac upper?
Gabriel B on Apr 18, 2018
BEST ANSWER: This is a PSA upper. All PTAC uppers will say so in the title and description.
Is the A2 Flash Hider pinned and welded?
Buss126 on Jul 18, 2018
BEST ANSWER: Wouldnt see why it would be on an 18" barrel. No it is not. This is usually a process on a 14 " to make it legal where 16 " is the minimum length barrel allowed without any other permit or status.

No feeding or ejecting issues and spot on up to 300 yards. Works well with a Nikon p 223 scope.

Phenominal value at budget cost!
I am writing this review after owning the upper for 3 months. I wanted to make sure that I had ample time to sufficiently evaluate it before saying anything. and all I can say is WOW. The upper is well capable of Sub-MOA groups (at least out to 100 yards). The load I am using is 24gr of Varget, Hornady 22cal 68gr HPBT, Winchester cases, and CCI #400 primers. I have a budget, Nikon P-223 (3-9) optic and a 3.5lb trigger.

Disclaimer: I would say I am a decent shot. Some days I do quite well, others not so much.

Great deal on a great built upper.
Great upper with no problems at all so far! The rail feels great, the upper and BCG fit, feel, and function flawlessly, and the MBUS went on nicely and are dead on accurate.

Simply a great value!
This upper went on my first ever build, and I am very pleased. I'm an average shooter, at best, yet have been able to achieve 1.25" five-shot groups at 100 yds with factory loads, using only a red-dot. 68 & 69 gr loads seem to work best.
