I am new to these AR guns and could use some direction... One has 223 WYLDE on the barrel and I was told 5.56 ammo would work thru it? It jammed a couple times when fast firing and I could see where the firing pin barely touched the primer. I see references recommending 5.56 "NATO" ammo. Are the bullets pictured acceptable?
Where is a good source for sights and accessories? I think I need a carry handle, rear sight combo like on the M 16.
Any help appreciated... Thanks Dale

5,56 and 223 will fire through your at platform. I’ve not fooled with the wylde caliber so I’m no help there. Most ar 15s are milspec and pretty much should be interchangeable with lots of parts easily available online. You might try breaking the rifle down and cleaning it well. The lightly oil and see if it locks up better and has less fail to fires.

The Wylde is capable of shoothing both .223 and 5.56.

Buddy had the same problem I changed out the firing pin with one I had and it worked fine after that you might try stronger springs in the trigger group those military primers are harder then normal primers so they say.

So 5.56 "NATO" is just a term for 5.56?

Do a web search on the difference in the 5.56 and .223 round.

DiggerDale, when the military started looking for a lighter round with less recoil they first looked at the 222. (which is really a 224 caliber) the 222 would not penetrate a military helmet at 500 yards which was one of the requirements they wanted. So Remington told them they had a 222 magnum. Military said we dont want a magnum (again 224) and shot it down without asking any more questions. So they told the Army have a look at this 223 cartridge. (224 caliber) Its light, and will pass the helmet test. So the military decided the round should be 5.56 X 45 NATO. Not 10 cents difference in 223 and 5.56 NATO other than the way pressure is tested. I have been told not to shoot the NATO round in a rifle chambered 223 but I have yet to see it ever cause a problem. No one says dont shoot 223 in a rifle chambered in 5.56 NATO.

FWIW a 22 hornet and a 220 swift are also 224 caliber.

Sure. 5.56 is a lazy man's way to say 5.56x45 NATO.

We can shoot .223 and 5.56 in a 5.56 AR, we can shoot those same rounds in a Wylde. I wouldn't recommend shooting 5.56 in a straight-up.223,

So here is what is stamped on the barrels.. The 5.56 would send rounds downrange as fast as I could pull the trigger. The 223 barrel misfired a couple times when rapid firing. Seller stated the 223 WILDE was a new build and 5.56 ammo would work fine. I am hoping it is only a lubrication or break in issue. I have a good supply of 5.56 and would rather save my 223 ammo for the bolt action. I would like to know of a good online parts place because both are in need of sights

Dale, palmetto state armory is a great source for parts for AR's. I've been doing business with them for a while great service. You're .223 wylde is safe to shoot 5.56 through. I'd first recommend taking your bolt apart and cleaning you're firing pin good if you haven't. If it's a new build some of those parts may be greasy or gunked up.



X2 it's easy to get the firing pin out if there is factory grease in there it can turn hard as a rock I had to sand some off with sandpaper once. Couple drops of good oil and let her rip.

Not confusing the 223 wylde can shoot both 5.56 and 223 however the 223 rem cannot fire 556. The wylde was built to handle the pressure of 556 nato.

Clean the bolt carrier group well.

Also are you sure both uppers have the same gas system?

My wylde had a buffer spring that was just a hair long. Id also check your buffer detent pin.

If you don't want to pay shipping most fun stores have parts readily available and average priced.

Midway USA has tons of parts too.

The wylde part refers to the chamber. I believe it has more freebore but a little tighter (the freebore part).

https://www.google.com/search?q=223...&rlz=1C1GCEA_en#imgrc=yRM90h65cD2bRM

Copy and paste that or just search 223 wylde chamber. There should be a drawing comparing the 5.56 nato to 223 rem and 223 wylde. For me it was on the top in the middle. EDIT: Looks like the link worked.

As some said, strip the bolt carrier group and give it a good clean.
Parts you can get at Palmetto state armory, Midway, Brownells, Numrich and a bunch of others.
When ordering from Midway, Ask James how he did it and then don't do it like he did.

The case is the same externally for .223 and 5.56. the difference is how the chamber is cut in the barrel. 5.56 can have higher pressures than .223. I'd one barrel is having problems with light primer strikes even after cleaning, you may have a headspacing issue in that barrel.

5.56 nato and .223 are dimensionally the same on the exterior.

NATO standard 5.56 is loaded hotter than most civilian .223 due to having to use non expending projectiles to maximize wounding.

The difference in the internal chamber dimensions in the barrel are different between the two.

A 5.56 chamber is a touch looser to allow cartridges to feed under adverse conditions as found on the battlefield also it has a greater freebore or space ahead of the bullet before the rifling starts to help keep pressures down under those same adverse conditions.

A .223 chamber is more of an exact fit as field conditions for a civilian are not expected to be as harsh.

This means a 5.56 fired in the tighter .223 could expect to run at a higher pressure, possibly unsafe levels.

A .223 fired in the looser 5.56 chamber should have lower than expected pressures than it would in its own chamber.

Also, all things being equal a .223 in a .223 chamber that fits well should be more inherently accurate than the 5.56 in a 5.56 chamber.

The wylde chamber is a compromise chamber between the two being a little bit tighter than a 5.56 but not as tight as a .233 but it keeps the 5.56 freebore to avoid pressure issues.

Basic rule of thumb, either can be fired in a 5.56 chamber but don't expect the level of accuracy a well fitted .223 chamber with .223 ammo. But only the most discerning and capable of shooters would even notice the difference.
Either in a wylde chamber with a possible increase in accuracy.
.223 only in a .223 chamber due to a possible increase in pressure that might reach unsafe levels. It most certainly will increase wear and tear if you choose otherwise.

BTW, the same deal of hot loaded NATO spec also applies to some degree in 9mm as well with some older pistol designs, browning hipower most notably.

5.56x45 and 5.56NATO are the same. Both are externally identical to .223 Remington.

Same deal as 9mm, 9x19, 9mm parabellum, 9mm Luger. All the same.

7.62x51 is 7.62NATO and the same as 308 Winchester though these don't have as big a pressure discrepancy as 5.56/.223. Most self loading military arms though are specced to function at just one pressure level as supplied by government ammo so civi ammo can have issues though not always.

Warrior laid it out clearly and concisely. If you research the issue on the internet you will find exactly what Warrior said.

Correction: 7.62 x 51 nato is .308.

You are correct, a brain fart from my days of playing around with a czarist marked mosin.
