I recently built a AR9 pistol w/a 11” barrel & man it’s been fun to plink with. I used a A2 upper & a Non F marked FSB. This will eventually be a “truck” gun, but for now it’s a for fun gun.
My question is, what is a good distance for setting up the sights? Right now it’s right around 45 - 50 yds, only because it was quicker to set it at that distance & get right to plinking. I would like to set it further. After I did some research there really isn’t a consensus on a distance. Some say 40 - 50yds while others say 75yds & even a 100yds. Given the scarcity & price of ammo these days I don’t want to waste more time & money if it’s not worth it. I would think for a 11” inch barrel a 100yds would be to far, however I don’t have any data to back that up.
Any thoughts or suggestions on the optimal or max distance for sighting it in at?
