I zeroed my DCM M1 at 100 yards with the sight set at that range.
The aperture seems to be quite high. I'm guessing it should be set at a battlesight setting of 200-250 yards.
Does anybody know the correct position for the battlesight setting?

Thanks in advance....

how many clicks up is your sight at 100 yards?
a lot of clicks wouldn't seem that great, but as long as you're under 20 you should be fine. Just click the sight back down and remember your zero. Post back, I'm not sure that there's any specific "battle sight" setting, just your rifles zero plus some come-ups, or a good 200/250 yard zero.

Look up fulton armaory on the web . they have some GREAT information on setting the sights,slings any history.

This should help you get started....

30-'06 M1 Rifle, M2 ball

Range ~ Approximate Adjustment

200 yards = 100 yard zero -1 click

300 yards = 200 yard +2 to 3 clicks

500 yards = 300 yard zero +7 to 8 clicks

NOTE: To initially establish your zero, first set the windage so that with windage index line on the rear sight base aligns with the center line of the windage guage on the receiver. This is mechanical zero.




(a) Iron sights (M1 rifle): The rear sight can be adjusted to correct for a wind that is strong enough to blow a bullet off its course, or simply to change the strike of the bullet to another spot on the target. The strike of the bullet can be made higher or lower (elevation) or can be moved to the right or to the left (windage). The elevation and windage knobs make audible clicks when they are turned, and each click changes the strike of the bullet approximately one inch on the target for every 100 yards of range. For example, 2 clicks of either elevation or windage will move the strike of the bullet approximately four inches on a target at a range of 200 yards. Windage can be adjusted 16 clicks to the right or to the left of center index, and elevation can be adjusted from 0 to 72 clicks.

(b) Zero and Battle-Sight for M1: Every rifle has certain characteristics that make the individual piece fire a little high, a little low, a little to the right or the left. To be able to get consistent hits, the rear sight must be zeroed for the various ranges, and the sight setting recorded. The data for the rifle's zero is easily kept in the accessory compartment of the stock for ready reference. To move the mean point of impact up, raise the rear sight. To move the mean point of impact to the right, move the sight to the right, and so on. Several rounds should be fired from a bench or sandbag rest from various ranges to find and confirm the zero settings. The battle sight setting is the 300-yard zero, less two clicks. When two click are subtracted from the zero elevation, it causes the rifle to be zeroed in at the point of aim. In other words, the location of the shot group is moved from the center of the bull's eye to the lower edge. With this sight setting, a rifleman can hit his point of aim at 300 yards and can engage man-sized targets at ranges from 0-400 yards by aiming at the center of mass.

(I) To calibrate the rear sight to the battle sight setting you:

Run the aperture all the way down and loosen the screw in the center of the elevating knob until you can turn the knob forward.
Turn the elevating knob forward until the 300-yard index line is opposite the index line on the receiver.
Turn the elevating knob forward from this point to the number of click equal to the 300-yard zero in elevation, less two clicks.
Hold the elevating knob in position with your left hand and tighten the center screw, then run the aperture all the way up and tighten the screw.
Check your setting by turning the elevating knob back until the 300-yard index line is opposite the index line on the receiver, then turn it as far forward as you can, counting the clicks. The number of clicks you can turn the elevating knob forward should be equal to your battle sight setting.
(II) To set the battle sight zero on the older type sight (with the locking nut) you:

Set the 300-yard zero in elevation less two click. Lock the rear sight at this point by tightening the locking nut.
Loosen the screw in the center of the elevating knob and turn the knob until the battle sight index line is opposite the index line on the receiver.
Tighten the screw in the center of the elevating knob.
Check the settings as described in (I) above.

GOOD LUCK! ;)

I read somewere that 1 click = 1 inch approx. Therefore if zeroed at 100 yrds 2 clicks up for 200 yrds. Battle sight for a 1903 springfield was (blade in down position) 547 yrds. So where the gun is sighted will give you a sighting point. Remember the rifle was looking for a kill zone of several inches + or - 5 inches will still do the job. If sighted dead on at 214 yrds the maximum point blank range is 251 yrds. (kill zone of 5 inches)

If new,sighting is needed,loosen it and bring it all the way down and then up 19 clicks and that will be approxamently 100 yards,from there work up to 300 yds and set it for the long mark and lock it ,that is battle sight that will be quickly accessable.

I was alway taught :
turn the sight all the way down to where it bottomed out.
Now center the rear sight on the rifle.
Now come up 11 clicks and you should be on the paper at 100-200. You'll of course have to adjust your wind also.
you can now loosten the screw on the sight adj. know and set it to "2" if you are satisfied with your range results.

i've done my Garand this way as well as my M1a.

I always had my M-1 Garand Zeroed in at 300 yards dead on the bulls eye! Now that was close to 3 inches high at 100 yards. This way you would be right on for most of your timed ( 5 to 10 seconds ) "Pop Up Targets" in the rifle range when firing for record.

You only had a few seconds to locate, fire and hit the target for your score. If on the way down and your bullet struck the target.....sorry, NO SORE! Your bullet had to strike and this electronically knocked the target back to its starting position. As I recall most of them were set between 50 yards and 350 yards. Your eyes has to scan up and down your firing lane, for the up coming target.

The KD Range (Known Distance Target) was set at 350 yards at Fort Lenard WOOD Missouri, back in the early 1960's and the target was simply a big black 18 inch Bulls Eye on a white 5foot X 5foot target. Now for this particular range score, I reset the sights on my M-1 Garand to strike 12 inches high at 350 yards.

This way I would in fact score a hit in the Black BULL, simply set the black round bulls eye on top of my front blade sight, holding, while I aimed at 6 O'CLOCK (bottom edge of the black bulls eye) on the Black Bulls Eye. I can't remember just how many clicks put that rifle on the money. I also remember that several of those rifles, would indeed vary in the amount of clicks to set the rifles dead on at a particular range such as 300 yards.

I shot in the top 10 of my Battalion back then and doing so earned a weekend pass and big hand shake with our full Bird Col.
I know for a fact that a lot of soldiers would be aiming at the center of the 18inch bulls eye, having the front blad sight wavering in the center.......which by the way was almost impossible to keep in the exact same spot every time, do to the color loss of black on black. The front sights were all blacken with "pot smoke" by the attending sargents prior to the fireline commencing fire.

you can now loosten the screw on the sight adj. know and set it to "2" if you are satisfied with your range results. i've done my Garand this way as well as my M1a. Excellent info!! I never knew that the rear was adjustable. I thought that you just write down/remember the clicks up or down. I looked at my rear sight and saw the markings, so I grabbed a good screw driver and calibrated the rear sight to "my" range at 100 yrds. 2 clicks up, it's on at 200 yrd mark, Just like it should be. This site is cool. Thanks m141a !!! :)

The standard sights are 1 MOA per click. National Match sights are 1/2 MOA per click. Double the clicks for NM sights

A tip a pro gave me once was once you are zeroed in mark your sight with some white or red paint (fingernail polish works) so you can easily return it back to a known zero.

If you don't shoot M2 ball - It is easy to plug the numbers in here and get the number of clicks for each range for your specific load.
