OK, here's my history lesson for the day. There are two most commonly chambered cartridges in the AR family of rifles. The civilian version is the .223 Remington SAAMI. The military variant is the 5.56x45mm NATO. .223 Remington and US 5.56mm ammunition are so similar that for all purposes the cartridge cases are interchangeable. The differences are slightly different in loaded ammunition.
There are slight differences in free bore diameter, free bore length and angle of throat. The the big differences are those in allowable chamber pressures. Rifles chambered for 5.56 NATO will handle pressures of 10,000 cup greater than one in .223 Rem. That means if you fire 5.56mm ammo in a rifle chambered for .223 Remington, it can have a chamber failure (explode).
So what does this mean? Check and see what your rifle is chambered for. You do not want to fire surplus military ammo in a rifle chambered for only .223 Rem SAAMI.
Luckily most manufactures produce rifles chambered for 5.56mm NATO/ .223 Rem. They are all stamped on the barrel, and if it is not the manufacturer can tell you what the chamber is.
That is the down and dirty on that, with out getting too complex and long winded. 5.56mm ammo in a rifle chambered only for .223 Rem= BAD, .223 Rem ammo in a rifle chambered for 5.56mm= GOOD.

ok B4, thanks for that info! my rifle is stamped with both markings on the barrel. I don't think that I have ever seen 5.56 ammo for sale (I never really looked) I was just wondering! When I was in High school, I had a kid in my class that owned a .223 AR-15 and he claimed that he hunted Black Bear with it. I would think that is a risky hobby! ok, thanks again! I am taking it to the range tomorrow!!!

No I do not have a link to the rule about 5 rounds in a spare mag, but I am quite sure that it would be interpeted as illegal by a warden. You might win in court, but it will ruin your day huning and cost you a day off from work, and if you lose, it might cost you much more. Your best bet would be to call the Fish and Game and ask for the law enforcement section and ask them. Al@THO THO Game Calls www.thogamecalls.com

Al@THO THO Game Calls www.thogamecalls.comIn September 2004 I asked NHFG law enforcement division and this was their reply. [glow=red,2,300] From: Bruce Bonenfant To: Paul Sent: Wednesday, September 15, 2004 3:45 PM Subject: RE: Hunting regulations question
Paul, You may use a high capacity magazine so long as you do not load more than 5 rounds into it. You do not need to plug the magazine in any way. While hunting with a semi-auto, you would therefore be allowed a total of 6 rounds, 5 in the magazine and 1 in the chamber. Sgt. Bonenfant [/glow] I keep a copy of this email in my truck in the event I'm ever stopped by a warden.

That's OK, I've been sick for a while!
I just happened to come across a couple of Rock River stripped lowers and needed another project to do. Plus, I need a good light brush rifle for coyotes.
