New to M&P 15 Sport (AR's in general)

[wagostini]

Hello Guys!

Like the title says, I am new to the AR platform and I have very little clue what I am doing. I know I want an optic sight on my sport but the issue that I am having is the Front Sight sits too high. I want to remove it and get a new gas block, but I am worried about buying the wrong piece. I want to exchange the heat shield eventually for one that has a quad rail. I know I am over thinking about things that I am going to do with it... I call it excitement. I just need that front sight gone (I am not a fan of iron sights).

Help me please!

I am looking at the Nikon Optics

Welcome to the wild world of "Legos for Men (and really awesome women". Resist the urge to buy every little gadget until you've spent some time with your new gun. You will find that you don't need most of it and they just add weight to the gun.

Most especially, take your time with optics. More money is wasted on optics than any other device for guns.

So, before you spend a dime, what is your intended purpose for this gun? Range gun? Hunting? Precision bench shooting? Three gun matches? Mercenary for hire?

What distances will you be shooting?

There is no point in suggesting optics until these are answered.

 

[wagostini]

Mostly range for the mean time, about 100 yards. Eventually once I'm good and accurate with the gun, minor hunting (small prey). I still have not gone for my hunting license.

You will not see the front sight tower at any power over 3x. That 4-12 Nikon is a big enough scope that it will look like the rifle is mounted on the scope, not the other way around. Consider something with less power.

If you plan on hunting with your AR, you will not need a quad rail unless you plan on mounting a light or bipod. Most are so sharp they are like grabbing a cheese grater.

If you are looking for a free float front end, then you have plenty of options. You can change out the gas block at that time. Go slow.

I looked at the model of Nikon below this one and it had no variable sight. I do have a rail riser mount.

What? No BUIS? (Back Up Iron Sights) No lights, quad rail, heck no! Penta rail at minimum!

Congrats on your new gun. I know little about scopes, but the front sight will not be a problem. Unless you just want it off. I would leave it on, if your drop your gun and damage the scope hunting, you can still hunt with the sights.

Like Rastoff said, take your time buying new 'tactical toys' for your AR. I bought all kinds of stuff, and the gun, besides one or two things is back to stock. Could have used that $ for ammo.

 

[wagostini]

I just mounted a .22 scope on it just to try it out and you are right, I can't see the front sight

This might work. Mount a scope and the zero will not change when you change uppers. Joe

Can't use irons well any more, so I find a decent optic necessary. The other thing most often needed (versus "wanted") is a decent trigger.

If I get really carried away, a dust cover with a witty saying visible when it opens up.

That suffices for me.

The other thing most often needed (versus "wanted") is a decent trigger.

Agreed, but my Sport trigger is actually pretty good....especially when I compare it to my stock Colt trigger which was god awful.

I used a Burris 1/2" raiser in order to clear the front sight. It kinda worked but it increases the bore to sight distance (scope height) which can cause a lot of frustration, especially since you have more screws to tighten and make sure they stay tight.

My personal opinion; if you like to use a scope on an AR type rifle get one with a gas block in the front. Get a quality base and scope. You even can add a 45 degree back up sight in case you have to shoot shorter distances.

If you want to keep the A2 front sight just get a carry handle. This is good enough for shooting out to 100yd. I'm sure many people are very accurate beyond 100yd using iron sights, depending on the target size...

If that thing was getting in the way of any optic I wanted I have a high speed cutting wheel and it would become very short. A file and some blueing would finish off the job, or maybe some camo tape. Dang I hate the looks of those front sights. Didn't like it on my issued AR16 and don't want one on a AR15. Don

Me too , that's why I bought a M&P 15OR. Irons folded out of the way and a Aimpoint PRO(2 MOA dot) for the optic.

 

[wagostini]

I decided to get the Nikon Optics. I tried one on and it cleared the front sight just fine. I found a great deal on it and I couldn't pass on it.

 

[wagostini]

Riser too much?

 

[cyphertext]

Riser too much?

Yes... Why do you have the riser on there? The mounts should set it at the proper height to allow for a good cheek weld.

 

[Maddmax]

Riser too much?

You want the bell of the scope (front end), as close to the barrel/hand guard as you can get it with out touching for best results. ALSO, check your eye relief so you don't have any dark shadows when looking through the scope. On mine, the rear of the scope sits almost flush with the back of the rear iron sight and charging handle.

Thanks for the tip! I'll be going to the range this Saturday and making adjustments.

Here's an idea for others that are faced with the same issue. Mounted a green-dot on the scope tube. The scope is a 3-9x w/lighted reticle.
The scope and green-dot are both available from NCStar. Green-dot available separately with mount for any 30mm tube, given you've room on the tube for it.
Shot of green-dot a bit blurry with a reflection too; best I could do with camera available.

 

[Magload]

It seams like that green dot would be better if you were to roll it 45 degrees right to get it closer to the bore. I guess if you were shooting really close you would be ok.
