15-22 Sights

I'm as excited as you guys are about my new rifle and I'm trying to chill on posting questions every 10 minutes but I am slightly confused about my sights. My Bushmaster was damn near perfect out of the box but my 15-22 elevation is way off. I have the windage perfect. Isn't the basic idea to have the elevation on the rear sight down as far as it will go, raise it a few clicks, then adjust the front sight until on target, then use the rear for fine tuning when needed such as different target distances? I'm hoping you can help as I can tell hundreds of you have these guns and probably went through the same thing. Thanks!!!!!!!

I went optical, so I am not feeling your pain.

I'm sure a forum member will have an answer for you shortly.

Yes. Rear sight should be low when sighting in at short distance. This allows you to rely on rear sight to adjust for increased distances and back.

Try the below method applying modifications where needed for the difference in trajectory.

note: When zeroed for 100 yards (91 meters), the trajectory of the standard high-velocity .22 LR with a 40-grain (2.6 g) bullet has a 2.7-inch (69 mm) rise at 50 yards (46 meters), and 10.8 inches (270 mm) drop at 150 yards (137 meters).[6] A .22 LR rifle needs to be zeroed for 75 yards (69 m) to avoid over-shooting small animals like squirrels at intermediate distances.[6] The newest commercial rimfire, the .17 Mach 2, is based on the .22 CCI Stinger version of the LR.
