I own one and have had it for about 4 months... Since then i have had to send it back due to the illumination switch being activated by the recoil of my TRG42 338lm... Night force had the scope fixed and back in my hands within a week.. mounted and slinging lead once again.... Again, i opened the switch to adjust the brightness of the illum reticle and it now feels that the scope will act the same once being fired. Is anyone else having these troubles?? Looks like ill have to prove it and call NF again about this returning issue.. anyone experiencing these issues with NF optics?? im not beating up on them, thus far they have done me right, i just dont see why im having the same issue again after i sent this off one time to fix it...
