i am on my second Kibler SMR "snap together" gun, LOL,,,,this morning i went deer hunting a while. i didn't see any deer and i also couldn't see the front sight! at 66 i have perfect eyes, i don't even need reading glasses, but the front sight is so thin in dim light you just can't see it. i will open the rear sight up and put on a wider front blade. has anybody done this and what front sight did you use? the base needs to be thin as the dovetail is cut shallow on these guns. thanks,,,,,,,,,,,,,,,,,,,
