researched diffs of 5.56 NATO and .223 Rem
I looked into the differences between the .223 Remington round and the 5.56mm NATO round. I get it. The specs for the two cartridges are close; but not the same. If pressed, one can fire a .223 round in an AR-15 chambered for a 5.56mm NATO round, but not the other way around due to the higher power inherent in the 5.56 round; and even that depends on the weight of the bullet.
I also read that one must look on the barrel to see how the weapon is chambered; it is stamped on the barrel…to be sure. As I mentioned, one can shoot a .223 round in the 5.56 rifle, but may lose some accuracy at longer distances.
Why build when one can buy complete? This is a good question and those of you who have been around firearms whether in the military or raised with guns, have an advantage to those of us who haven’t. I am starting to see how one can buy an M4 platform, that will allow, depending on lower and upper receiver combos, one to change out between AR-15, 7.62X39 (AK-47), and 300 blackout.
For a few thousand dollars one can have several options on how one wants to shoot; defend, patrol, sniper.
For myself, I am looking to purchase an AR-15 already built, chambered in a 5.56 NATO…because I can shoot both rounds and I am not concerned initially about being super accurate at distances over 60 yards.
chrome lined barrel? why or why not? Chrome lined barrels extend the life of your weapon by about 5000 rounds from what I have read.
complete gun without sites?
what about sights? so damn many out there..open sights, optics, lasers…how does one choose?
Most of the lower end priced AR-15 come with what is called ‘flat top’. I take that as no sights at all.
Well shit. I don’t care how good you are, ya gotta have sights. Whether iron or peep or scopes or optics or red dot or green dot or laser or whatever the hell is out there.
Red dot sights are $400. That’s pretty steep if you just spent $800 on a rifle.
What’s with the carrying handle? Is it part of the sight? Fold down, flip up geez, a rookie would get screwed buying a gun without having a clue, and probably many buyers do.
Do ya need a sling if ya gotta carrying handle? Like belt and suspenders?
I am still looking and I am getting smarter.
is there a site out there that splains all? I have not found it…
A final note on ammo; from what I have read, .223 is cheaper than 5.56 NATO. The 5.56 round was invented so that bullet would still be hypersonic at 500 yards out of the muzzle. Let’s see…sound travels roughly at 1000 fps…500 yards is 1500 ft.
Our pal Stakz has a really impressive post on .556 ammo here.
You experts out there don’t stomp on me if I got something wrong. This blog is about information; not being corrected.
