View Full Version : Colt AR-15 A2???
November 28, 2009, 12:02 AM
What's a good price for a used Colt AR-15 A2??? Also will the A2 shoot both 5.56 and .223. Are there any issues with shooting .223 form it? Thanks.

If it's marked 5.56mm (which I suspect it is) then it will shoot .223 just fine. 5.56 has a bit more stank on it (50-100fps) but you have a much wider selection of .223 factory ammo for hunting. My only suggestion is that if you have a genuine Colt take care of it and don't feed it cheap steel cased Russian ammo.

At gun shows around memphis i have seen them lately for around $1000. Gun shows around here are usually a little high.

Actually its marked .223. So does that mean I cant shoot 5.56???

Make sure you are looking at the markings on the barrel not the lower reciever. I am betting it is 5.56. Never rely on the reciever for accurate chambering information.

If the rifle is stamped .223 on the barrel without any mention of 5.56mm then it is USUALLY not recommended that you shoot 5.56mm ammo in it (the Ruger Mini-14 being the general exception, but they tell you so in the instruction book with the Ruger). Sorry, but it's complicated if your rifle isn't clearly stamped 5.56mm.
The good news is that there's plenty of inexpensive .223 all over the place so it's really not an issue unless you make it one.

I thought chambers for 5.56 were cut different with more free bore so unfired cartridges could be more easily extracted. also, I think the 5.56 brass is thicker and the 5.56 bullet is seated deeper.

It is 45 mm Dave.
Op, just read this for the answer on the differences.
