probably no more than a TA11 BAC. need to remember what targets and distance you are engaging in order to use the BDC properly...actually, thatr's true with all ACOGs, i would think. again, the close, hose down stuff seem to warrant the 1x...after 100 or so, i'm dialing it to magnification depending upon target distance and then figuring out what part of the reticle to use-just like and ACOG. the only "i wonder" on this scope is the BDC accuaracy with the FFP.
