Ok, i have a RRA 16" mid length. I have the yankee hill fold down front sight, and the arms #40L fold down rear sight. Is there a method to use to bore sight this? I thought I read somewhere that as long as your rear sight was centered, and the front sight post was raised X amount of mm that it'd give a pretty decent bore sight. Anyone have any ideas?

You can do a couple things. 1 is to just buy a cheap 30-50 dollar laser bore sighter and sight it in to get it on paper (these can be done at home within 25 yards). 2 is to field trip the entire gun and remove the bolt, look down the barrel and place the barrel on the bullseye. Then without touching the upper at all, adjust the sights to get it horizontally correct and lined with the bullseye. Vertical alignment changes with distance and I would not mess with the front sight post yet. Typically AR's are sighted for 300 meters which is fairly close to 300 yards. Adjust the front sight post accordingly to what type of shooting you do most. I normally vertically adjust while shooting the firearm. If you plan on getting a red-dot, scope or EOTech design, then you can mark the ticks for different ranges. I have marked my EOTech for 100, 200, and 300 yards.

I was attempting to sight it in at 50 yards last time I had a chance to shoot at any distance. I didn't quite make it. I was able to hit a 12 inch target several times at 330 yards by aiming just slightly high with how it was setup from stock. So it must be fairly close. I took it to my range yesterday, which is only 25 yards and that sucks cuz it's hard to sight in that way. However i did read that at 25 yards, if you're sighted in for 50 it will hit about 1.5" low. that's where most of my shots were hitting pretty much.

I did see a magnetic boresighter by leupold at scheels today. it was $70, said it can be used for iron sights and it allows you to change the distances it's sighted for. I didn't want to spend that kind of money though!

My "Sight Mark" laser bore sighter in 7.62x39 arrived today. Nasty outside so I took the longest distance inside (about 30') and dialed the scope to the laser dot on the supplied target. Piece O' Cake :razz:...Now I just have to get to the range.

Let me know how that sucker works. I've been on the fence about buying one for some time now. I just always seem to have another accessory or gun ahead on the priority list :rolleyes:
