Ran across these, these are current issue BUIS from what I read. My question is, what I see on the drum in the pictures is gradations from 200-600 yards; does this mean it's for 200min when your optic fails? And of course I'm presuming this only works with a AR front.

...the elevation lines run from 200 to 600 meters...with a point blank radius of ~ 5 inches out to about 350 yards when zeroed @ 25 yards POA=POI using the line inbetween the 300 and 400 meter lines...using M855 ammunition...if i remember correctly...KuroNeko said:Ran across these, these are current issue BUIS from what I read.

...my perfered method is to zero @ 50 yards @ the 200 meter setting...and leave it there...giving you a point blank radious of ~ 1 inch out to slightly past 200 meters...and then hold over...
...there are BUIS...not target sights...and designed to allow you to make torso hits on a man sized target...with a 50 yard zero...if your optic fails...just aim POA=POI...out to about 250/300 yards....then hold over...
...you'll almost never...if ever...be engaging targets past 300 yards...
...yes...designed to be used with the M4's F marked front sight base using the shorter .270 inch post...
Thanks Ullie ^^b
