New sight question

[novan3]

Added new rear sight that's not sighted in yet. RDS already sighted in so adjusted rear sight's windage to centre the reddot with A2 front sight to get LW 1/3 CW.

Is it normal for the rear sight to 'not be centered' to be sighted in? As you can see its a few clicks to the left.


Windage adjusted to the left a few

rear folders are often many, many clicks left or right.. the last troy i zerod was something like 25 clicks right, on a weapon with a known straight FSB.

but zeroing irons to dot is totally no-go.. you need to zero irons, and if you like, zero the dot to the irons if you have an absolute cowitness- which is looks like you do not. cant do it the other way around.

Iron sights always get zero'd first.

Understood, thanks!

Big fan of your work by the way, Stickman :)

No. RDS scopes have no paralax, RDS must be zeroed independently.

Once you have the RDS zeroed. Pop up the iron sights and then move your head slightly left and right and watch as the dot moves away from the tip of the front sight.

until that day,

As Stick mentioned, irons get sighted in first.

You say your optic is zeroed.

If your optic was not zeroed, to expedite zeroing of your optic, you can adjust the dot to sit on top of the FSP after the irons have been zeroed.

This will get you in the ballpark and on the paper, where hopefully minimal adjustments would be needed from that point forward.

I was always wondering the same thing, just never thought to ask about it. Every single Troy rear folding BUIS I've ever owned and mounted on every diff upper I've ever owned looks identical, more or less, to your pics up above. I always shoot to the right when BZO-ing new Troy BUIS', so the rear sight always moves quite a bit left.

IIRC, my KAC rears are the same way too. Weird.

Semper Fi,

If the RDS is already zeroed, why not just turn it off and zero the BUIS.

I did the same thing a while back when I changhed out one BUIS for another.

May be generally accepted BUS gets sighted in first, but if your RDS is already there, adjusting irons to dot works also.

Took 3 clicks left for sweet spot.
