I just got a Leupold Mark4 ERT 6.5x20 FFP and mounted it in a larue LT-104 on my ar-15 in .223.
The scope has M5 knobs, so .1 mils per click. I counted the total clicks available in elevation to be 23.2 mils, and factory zero being 11.6 mils from bottomed out.
When I went to sight it in, it was shooting almost 4 mils low from the factory zero - i.e. it took 40 (fourty) .1mil clicks UP to get the scope zero'd.
Everything works fine, but now I only have 7.3 mils available in the UP direction for shooting long range, which is only getting me to about 600 yards before I have to starting adding in hold over of 4 mils...which gets me to 900. I want to shoot 1000 yards, but need 13 mils of adjustment - which is more than the holdover + click adjustment available.
My question is, is 4 mils (40 clicks) of elevation to get it zero'd showing something wrong with the rifle? I'm sitting on a scope that has 15.9 mils available DOWN, but only 7.3 mils UP and it's driving me crazy.
Even larue's LT-158 only adds 10MOA which is 2.9 Mils approximately...which still puts me short of 1000 yards with this rifle.
Is there anything to be done? I think the weapon has tied my hands, as I can't shim the larue mount, and i'm not sure what else could be done....any inputs appreciated, and sorry for the huge first post.
