Well, I have to admit it, I have been suffering from BRD a little lately (Black Rifle Disease). and ARs (Another Rifle)s have found there way into my gun collection.
I have had a 5.56 for about a year or so, and my latest add is a 6.8. Both of them are effective at far less range than the M14, but for women, children, and guys who don't / won't train, well let's say that a 150meter rifle is fine for them!
Saw a chart the other day recommended to me by a friend. Over at the ammo oracle.
Interesting stuff about what velocity the 5.56 stops fragmenting, and what length of barrel keeps the bullet going that fast out to certain ranges. Turns out that my 16" M4gery is good with 55grain projos out to 150 meters, but a 14.5" is only good to about 100 meters!!
Black rifles will never replace my M14 for that AT&T moment.. (For you young guys AT&T made famous a commercial about "reach out and touch someone"...)
