These are some sights for an AR15 made with the circle game and middle finger. The front hand is significantly smaller than the rear. Is is on purpose as i made them to line up height wise so that they would be accurate.
I haven't printed this so I don't know how well it works, but oh well...It was just something fun to make.
UPDATE 1/25/19 - i made an adjustable front sight post. It's made to attach w a 5mm bolt. I have not tested any of these designs so if you print one please post a make with photos. if it works for you and you'd like to send a tip, you can send it on paypal to firstname.lastname@example.org
