I scanned this article for the forum since a few of our more valued forum members are now interested in AR15 related stuff.
I'm really not too keen on violating any magazine copyright laws so I'm only going to leave this posted for 24 hours then it will be gone off the web.
So save it to your personal computer if you want it for keeps.
Since there are only a handful of forum members that are totally goofy over the AR...I figure that if I just leave this posted for a very short while....then that is "akin" to just leaving a copy of Shooting Times at the local barber shop for a select few haircut customers to look at.
Here it is...there seems to be some valuable ballistic & "rate of twist" info. contained in this article. Enjoy.
