M&P 15 sport ii front sight tool

[carbon summit]

Approx 1.2 moa per 'click' on the F marked front sight. I'm surprised you didn't learn that in the Army. Maybe you just forgot.

My DD-214 is 23 years old!

Minutes Of Angle is new to me. Granted I've been out of the Army for years, and even then I was a mechanic not 11B so maybe we just were not exposed to it. Go qualify and then get back to the shop!

I found a picture of the targets we used and it told us what clicks to do without really knowing what it meant. Did anyone on here who was in the military learn MOA?

I guess this old dog needs to learn new tricks!

Which target to use?

And another question for the more experienced M&P 15 owners than I am.

The M16 has a 20" barrel.
The M4 has a 14.5" barrel.
The M&P 15 Sport II has a 16" barrel.

Which of the attached targets do you think would be better to use with the M&P 15?

Sorry, my last post wanted you to download them just to see them.

I use the M4 version. 16 is closer than 14.5 than 20. It's close enough for my use.

I was thinking the same logic but we didn't have M4s when I was in so I didn't know if there was a different reason for the different targets other than barrel length.

Thanks for the response!

ELEVATION: 1 'click' adjustment at 25 yards

1 moa = 1" @ 100 yards (2" @ 200 yds. 3" @ 300 yds and so on)

A1 Front Post (Round) 20" Barrel = 1/4" (1 moa)
A1 Front Post (Round) 14.5"/16" Barrel = 3/8" (1.5 moa)
A2/A3 Front Post (Square) 20" Barrel = 3/8" (1.5 moa)
A2/A3 Front Post (Square) 14.5"/16" Barrel = 1/2" (2 moa)

So, depending on your particular rifle type/front sight type, it's still going to average somewhere around 1.2 moa +/-

The difference between the targets for sighting in has more to do with the difference between sight separation of rifle and carbine than it does with barrel length.

OK, a minute of angle is 1.047 in at 100 yards. At 25 yards, 0.26 in. [That 0.047 in can add up big time way out there.]

Rifle with A2 sights: front sight, 1.25 MOA elevation per click; rear sight 1/2 MOA windage per click/1 MOA elevation per click.

Carbine with A2 sights: front sight, 1.875 MOA elevation per click; rear sight 3/4 MOA windage per click/ 1.5 MOA elevation per click.

If your rifle has A1 type sights the rifle version has 1 MOA per click adjustments for both windage and elevation. The carbine version has 1.5 MOA adjustments for both windage and elevation.

I got a new sight post for my rifle and now it all works just fine. My rifle must have come with an out of spec sight post that was too big.

Figured I'd post this so if anyone else has this issue and finds this post they can save some time and just order a new post vs worrying about different sight tools. ALL my site tools work fine now.

Good deal. Now how about unassing that giant bold red font.
