Hi, here i´ve build me a mirror sight for testing if it´s may something for me !?!?!? I used double mirror´s so there is no side switch by the mirror !!! If ... shure i´m gonna build a housing for, may i use some bigger mirrors too etc. First it Needs to be trained, the handle of the marker 90° turned + the scope like aiming. But human is a "Gewohnheitstier"(german) so that means if you go use it often you will get trained with and at the end you go think it´s like normal using !!!
