Alamo,
I got the MGM switchview lever in @ the beginning of the week; pretty sweet. i like the length of the lever...it's not obnoxiously protruding, but enough for some leverage. some leverage was definately needed, changing the magnification requires a bit of muscle. hopefully it loosens up a bit down the road.
i believe i found a decent spot on the rifle to optimize eye relief; i have it on a larue SPR-E mount.
it's pushed pretty far foward because I run the VLTOR stock on the third position setting "3".
