AR question...

[x-ring]

I've got a pre-ban ("registered") HBAR Colt AR .223 match rifle. I'm also left handed.

Trying to find definitive reading (LAW) on changing the upper to a STAG 6HL (their new Varminter is very accurate). It's also chambered in 5.56 instead of .223 so I can shoot milsurp ammo, etc.

Unlike bolt rifles (as you know) the receiver has both the serno AND the caliber listed on it.

Anyone direct me toward a reliable source for this? Thanks in advance...

You can put any upper you want on a Registered AW. No barrels under 16 inches tho.

Further, you can also have any and all features on that rifle now (flash hider, collapsible stock, bayonet lug, etc) since the federal AWB has sunset.

Your Colt upper is chambered in 5.56 anyway, btw. Look at the stamping towards the front of the barrel. That's what tells you the type of ammo for which your barrel is chambered, not the marking on the lower.

The caliber markings on the lower do not create any restrictions on what caliber upper you can put on it. You must always go by what is stamped on the barrel.

OK i just got really confused. .223 and 5.56 are the same? So the question confuse me. At least i hope so considering i have been shooting both in the same gun for years.

^no 5.56 has higher pressures and shouldnt be shot in a barrel marked .223

In a hunting style bolt action i could understand that. But in his situation is it not the same since it is a AR15? I mean in his owners manual I am pretty certain it says it shoots 223 and 5.56.

One more thing if it is so different why then do most ammo places that sell ammo list it as 223/5.56?

Here are a few Examples

RRA states that with their Wylde barrels you can shoot either.

The .223 Wylde chamber was designed as a match chambering for semi-automatic rifles. It will accomodate both .223 Rem and 5.56mm NATO ammunition. It is relieved in the case body to aid in extraction and features a shorter throat for improved accuracy.

From what I understand, a barrel for 5.56 can safely shoot 223, but a barrel for 223 shouldn't shoot 5.56.

Google is your friend. It is amazing what you can find on the internet.

The thing is, this IS also the internet. People use these sites for information, just like someone like you might use Google.. I would rather have someone tell me something on a site like this, than google it and read some article that had been written by some other random person. Either way, it doesn't hurt to try google too

Almost all modern barrels can shoot both.

It's always best to check your manual and/or call the manufacturer.

Man I was geting ready to panic for a second, lol! I am still a n00b to the whole AR game, even though I ma piecing together my first AR right now. I bought a case of .223 55 grain for my AR. The barrel is a Mil Spec 5.56 with a 1/7 RHT, I was looking for 5.56 ammo and .223 always pops up. So I went ahead and ordered the .223 since it is the same that the Mil uses lol! Okay enough of my n00biness!
