There is a reason so many competition shooters are using the 1-4 and 1-6x scopes. You get the same up close CQB picture that makes the red dots so popular. But you also get the magnification to make much longer shots. Saying a red dot is as good as a magnified optic is like saying scopes are useless at longer ranges.
Some caliber's ballistics lend themselves to long rang accuracy and some do not. I don't think you would see a 7.62x39 at an F class shoot. But I guess anything is possible if you work at it hard enough. It's really a caliber that I would limit to 300 yard shots, as you indicate. And probably 200 yard shots, depending on the gun. I am hoping the VZ2008 will get me to 300 yards with reasonable consistency on an 8" target, as it sounds to be more accurate than most 7.62x39 guns.
What size MOA dot do you have on your red dot? Hopefully a 1 or 2.
RSR, so you're saying a scope mounted on the receiver cover will get dinged up by the ejecting brass? How does the scope length affect that? Does it have to be a short scope mounted all the way to the rear to keep from getting hit by the brass?
Oh... and Merry Christmas everyone!
