joshxdm9 Posted December 29, 2013 Share Posted December 29, 2013 So I was at the range yesterday with a couple buddies practicing for 3gun. One of the guys needed to zero a new set of iron sights on his AR that he built. He grabs some of my 5.56 ammo (about 60rds) and zeroes his gun. So a little later the 5.56 / .223 discussion is brought up and he says his is a .223 barrel !!! And then says well you can shoot 5.56 out of a .223 ... I told him no its the other way around. So we check his pieced together gun for any markings on the barrel and could not see anything marked .223 or 5.56. We are going to take hand guard off to see if it is just covered up. If we are unable to find any markings or it does say .223 should he replace the barrel or have it checked out by someone or just continue to shoot it and now worry about it??

T Bacus Posted December 29, 2013 Share Posted December 29, 2013 It is not unsafe to fire 5.56 from a 223 chamber. There could be function issues from higher than normal pressures is the 223 chamber is on the tight side, but it would be at no time unsafe. This is a myth fueled by the internet. I would also be willing to bet his barrel is chambered in 5.56 so it really doesn't matter. Link to comment Share on other sites More sharing options...
Steve RA Posted December 29, 2013 Share Posted December 29, 2013 It lived thru 60 rounds so the odds are it would continue to do so. Link to comment Share on other sites More sharing options...
mpeltier Posted December 29, 2013 Share Posted December 29, 2013 I wouldn't worry about it. Link to comment Share on other sites More sharing options...
trouble Posted December 29, 2013 Share Posted December 29, 2013 I know a guy that shot around 800 to 1000 5.56 rounds from a Ruger .223 bolt action rifle. The rifle is still alive and well. Its not a good practice to get into but I bet that your barrel is just fine. Link to comment Share on other sites More sharing options...
warpspeed Posted December 29, 2013 Share Posted December 29, 2013 I don't think there is much to worry about. Link to comment Share on other sites More sharing options...
CarRacer Posted December 29, 2013 Share Posted December 29, 2013 This is a *very* long read up on what everyone else is saying but it has lots of actual testing involved in it to help provide factual information. http://www.luckygunner.com/labs/5-56-vs-223/ Link to comment Share on other sites More sharing options...
