Can someone please explain the numbers on the elevation drum. I have been reading the articles on how to zero the rifle, but im still confused on if the numbers correspond to distance, or just MOA.
Thanks |

Depends on which drum you have. Most are in METERs 300-600 (detachable handle) or 300-800 (fixed handled upper). (3=300M, 4=400M, etc) Some rifles have 'match' drums which count up by 5 (0, 5, 10, 15 etc) these number represent 'clicks' and are used by some match shooters to dial in for thier load and shooting positoin. For example 5 might be for shooting 200M with their 69gr load, while 53 might be the setting for the 600y using a 80gr load. |

Quoted: Yes on the range.I have a 6/3 drum so then its 300m,400m, 500m, 600m? If i go from shooting at 50 yards to 100 yards do I need to make any changes? On the 50/100 Depends on skill level and amount of precision you're looking for. If you're plinking, or praciticing 'defensive' shooting (like from a carbine course) a 50Y zero is all you need out to 300M. With a 50y zero the bullet is within 2.5" of the point of aim from muzzle to about 230y (depending on the load used). If you're shooting 'X's at 100y then I'd suggest adjusting the sights. Molon has a writup on zeroing so your rifle can have a 100M zero, 50/200M zero, and of course the range settings on your elevation wheel will still work (http://www.ar15.com/forums/topic.html?b=3&f=18&t=328143). |
