What's the difference between this one and the 516446673?

What is the difference in the 223 Wilde and a normal 223 and is it safe and accurate to fire the 556 and a normal 223 in this upper?
Steven L on Jul 13, 2018
BEST ANSWER: A quick search turned this up, “Well, the most obvious reason [reharding using a 223 Wylde] is that you can fire .223 ammo without giving up accuracy and 5.56 ammo without worrying about excess pressure. Sure, you can fire .223 ammo all day from a 5.56 without worrying about pressure problems thanks to generous chamber size, but if you really want to tighten those groups that .2240 freebore diameter helps. In fact, .223 Wylde chambers are known for extreme accuracy, which is better on the whole than what you can expect from a standard 5.56×45 chamber.”

How well does this upper with a rifle gas system marry up to the Blackhawk carbine butstock? Is the buffer and spring adequate or should they be beefed up
Darin A on Jan 14, 2019
BEST ANSWER: I took a complete, psa lower coupled with this upper and had no problems after a proper gas block alignment, which, be warned, you may need to do or have done if you go with this upper. Once gas was flowing properly it runs like a clock! I’m sure you’ll have the same results assuming the Blackhawk has the same springs as my psa-magpul moe enhanced lower. Goodluck!

Will this upper work with the psa gen 2 lower?
Richyrich on Feb 16, 2019
BEST ANSWER: It should work just fine. I put mine on a Anderson lower. Any mil-spec lower should work.

It’s a great upper.
I my upper likes Winchester USA READY .223 62 grain “Open tip”. The federal premium 69 grain Sierra matching BTHP had to be the best grouping!
Sorry I had to ad my big dog Mikado!

It looked great at University of boxing. The fore grip had what appeared to impact marks from some kind of adjustment? I installed on my lower and put on a scope. I attempted to sight it in but the shot grouping was all over like 4" off. I found the barrel was flexing and hitting thefore grip. I removed it and ground the interference places down.
I'm a very busy person so instead of sending it back. I fixed it myself. Also the gas block wasn't in line with the gas port in the tube and also the barrel. Also fixed that. I finally had time to sight it in and now it's 3/4" spread in 80 yards.

Really like it. It perfomed very well right out of the box. Built it with an anderson lower and a red dot scope for shorter distances.

Very accurate rifle
Bought this along with stripped lower and parts kit. Received it yesterday and finished the build last night. Rifle will be a police patrol rifle but I temporarily mounted a good scope and went to the range today. After about 15 rounds to zero, I fired a .6 MOA group at 100 yards. I am very impressed. Upper and lower have a good tight fit and all parts were first class. This is my first PSA purchase but I highly recommend them.
