    Ok, I was reading another forum at the S&W site, someone was having problems with iron sights so one of the comments stated they should be using the larger opening on the rear sight for up to 200 yards and then use the small opening for 300 yards +, is this correct? Thank you.

    I think there is some confusion here, when using iron sights up to 75 yards should the small or large opening on rear sight be used.

    For 'quick' shooting (CQB) I use the large aperture. At ABOUT (circumstances my very so this a just a guide line) the 25 yd line I switch to the smaller aperture.

    The large aperture is for cqb, night fire, protective mask firing and short range (about 25 meters)

    From US Army - Operator's Manual for M16 and M16A1 rifles TM 9-1005-249-10 dated 1985

    1 REAR SIGHT - Has two apertures for range.
    Use the unmarked aperture for targets from 0 -300 meter.
    Use the aperture marked L for targets from 300-400 meters.


    US Army - Rifle Marksmanship M16 and M4 Series Weapons (2008) FM 3-22.9 dated 2008

    2. For M16A2/3/4, M4, and M4A1 weapons only: Soldiers should use the
    unmarked aperture for zeroing and target engagement at all distances on the KD
    range. When engaging targets beyond 300 meters, the windage knob should be
    adjusted to the range of the target. 400-meter targets will be set on 4 flush, and
    450-meter targets will be set on 4 plus two clicks.
    3. For M16A1 rifles only: Soldiers should use the unmarked aperture (short-range) for refining zero at 300 meters. For target engagements beyond the 300-meter line, Soldiers should use the long-range aperture (L).

    Any alignment error between the front and rear sights repeats itself for every ½ meter the bullet travels. For example, at the 25-meter line, any error in rifle alignment is multiplied 50 times. If the bullet is misaligned by 1/10 of an inch, it causes a target 300 meters away to be missed by 5 feet.


    Hope this helps

    Many hunters in this area would remove the aperture insert and use the large opening, personally this has never worked for me, heck I had a scope on my BB gun.

    This is all news to me.

    I was operating under the assumption (duh me:eek:) the rear flip

    sight larger opening was for fast targeting, under pressure,

    and the smaller aperture was for precise shooting. Ah well.

    My eyes are too old for iron sights, so now I put a scope on my carbine and my deer rifle.

    In the Marines we only used the large aperture for night fire no longer than a 100 yards. Under normal conditions we never shot with it. At the range to qualify ,you only use the small aperture at 200, 300, and 500 yards. The sights were the A2 style sights. I guess it's up to personal preference but I would never use it unless it's for CQB.
