did he say a sticker?
lol
those are just a few of whats available..
i personally have taken to the mil system..
it has been alot of werk to make it somewhat full proof,
and i just change bullets lol and had to start all over,
but it worked out even better with the new shells, cause i dont have ta do much guessing this way,
and its set up fer all of my feeders.
no knobs , just point and shoot..
whats nice is my fittin to be 12 y/o daughter has taken to the mil, and is callin out which mil to use, and she even came with an accurate windage mil as well..put me inside of 6" from the bull at 574yrds. proud papa...lol she is the smart one..i just shoot the gun lol
