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.

Great cost vs performance
I was looking around for an affordable upper and stumbled across psa. I looked at some of the reviews and spoke to a few guys who know a lot about AR builds and they reinforced my instinct on purchasing my upper through psa. Since my purchase of my upper I have ordered three more times from psa and haven’t been disappointed yet! They offer great value vs performance, ship quickly, and are a proud USA company. What more could a guy ask for!!! I highly recommend any of there products to anyone who wants a great AR platform without breaking the bank.

Great upper
Seems to be well made and works flawlessly.
Thought I was having issues with the gas block causing short stroking. PSA was quick to get it tested and sent back to me.

Very good AR-15.
After shopping around at different companies, I decided to go with PSA from the advice of a buddy. For one thing the price is great, hard to beat. This is my first AR. Bought both upper and lower from PSA. So far I've only put 50 rounds through it. Very impressed with it and it shoots good so far.

Great Upper, great price.
Fit and finish is great. Accuracy is good, I really like the slim handguard. About 350 rounds so far, zero malfunctions. I only wish they had this minus the BCG in stock. It comes with a good BCG but I like the NB BCG because they are smoother and easier to clean.
