Scope a Flat-Top with a standard front sight.

After searching for awhile, I finallaly found an AR rifle with a Flat-top that will work with my budget. (I hope).

The problem is, that it has a standard AR front sight. Like the the ones used on the carry handle style. (Forgive me, I'm new to ARs and don't know the technical names of the parts)

How would I go about scoping this AR with that "huge" front sight in the way?
If I do find a way to get it pretty much above the sight, will the scope adjust enough down in elevation to even work with out having a zero of like 600+ yards?

Or will the front sight even been seen in the scope?
I know with MANY of my bolt actions the sight are not seen in the scope, and they are obstructing 1/4 of the front lens.

Thanks for any help.....
I just don't want to buy something only to have it NOT work the way I hope it will...

You shouldn't even notice it.

Nevermore is right. Zero like normal you will not notice the sight at 4x and above. At lower mags its is not an issue but you will see it.

You must be using a scope base that raises the scope a bit, because if I use normal rings mounted to the flattop, I can't see past the front sight using a Leupold 4x scope.

You need to use a mount that places the scope at the same height the Irons would be. Such as Larue.

Here is one of my guns with a fixed front sight.

Slightly taller scope rings will do the trick if you don't want to spend much. That's what I used to use, or short rings with a riser.

The preferable way to mount a mag scope, IMO, would be with QD scope mount like Bobro, LaRue, or ADM. I prefer the Bobro's attachment method, but they're all fine scope mounts. Downside is they'll run you $170-230, but you'll be able to remove it and put it back on without losing zero. Depends if that's something you need.

i believe in having the scope as close to the center of the bore as possible. I have found the if you use a low power scope you can see the friend sight, but it is not a problem. anything above 4 power and your not going to really notice it, maybe just a small shadow in the bottom.

I use a Burris P.E.P.R mount with a Millet DMS scope. Got less than $300 into the two of them and the front site is not a issue at all.

On an Ar the scope should not be lower than where the irons would be mainly because you will not be able to get a good cheek weld with a really low optic.

If you are buying a scope . . .

Usually shoot at 100 yards plus . . .

Where acuracy is important . . .

Where I would free float my hardguards . . .

And if you free float your handguards . . .

You can put a low profile gas block . .

Eliminating that standard FSB.

If you scope it, free float and ditch the FSB.

I prefer not to have a front sight base but you don't have to ditch it. Scopes work just fine with or without it.

I think I should send the extra money and get the heavier barrel, and no front sight. Sounds like it will be just as expensive both ways?

Thanks Everyone for the help. I'll just opt for the DPMS LoPro Classic if I can find one. I'm stuck at around an $800.00 budget...

I recently put a lightwieght Bushy flat top w/front sight tower on a Cavalry Arms lower. My scope is a 1-3x Weaver, which is a great low power AR scope, btw. The mount I usually like without spending too much money is the Armalite one piece because it places the center line of the scope right at the height of the normal iron sights, and it can be mounted forward for enough to the the eye relief I need. With this settup, though, I was looking through the front sight on low power, and it was also visible enough to be distracting at 3x. So, I switched to a Burris PEPR mount, which is a bit higher, and I'm very happy with it. Yeah, you can still see the fs, but it's below the crosshairs and isn't distracting.

On guns without the front tower the Aramlite mount is just about perfect. Unless QD is a really important feature for you, in which case the LaRue is probably the best there is.

What's the flat top option you were looking at for $800?

It may be a better choice than the DPMS Lo-Pro.

The front sight tower really doesn't block your view that much. As others have said, you see it, but it's not a big deal.

I'd take a good look at Stag in that price range.

Take a look at Del-Ton. They make great stuff. You could build your own for between $550 and $650. Or they sell complete rifles for around $750. I just finished a flat top build and I'm in your boat. I got a standard front sight. I'm going to put a Burris Fairfield II 3x-9X on it in a Burris P.E.P.R mount. A friend of mine has that setup and loves it.

I think the question has been answered, but since I just got of the phone with LaRue, I wanted to double check.

I have a standard front site post. I shoot nose to the charging handle.

Ordered a LT-139 with both 30mm and 1" rings.
I'm planning on trying to run a 1" Leopold 3x9x40 for load workup and range work, then swap out the rings and use the same mount for a Vortex 1-4 Viper when they become available or Burris XTR 1-4, I'm still waiting on the reviews and availability on the 30mm Vortex.

My questions is about the front sight getting in the way? From the post above it sounds like it will be visible on the lower power settings, but below the crosshair, do I have this right?

Should I be concerned about the LT-139 being to far forward? Will this cause issues with the front sight versus the LT-104?

I agree, build. Just completed range testing two very inexpensive 20" flat top guns. Half inch groups at 100 yards with Privi 62 grain FMJ ammo.

Bushnell Trophy 3x9 inch scope on cheap CAA rings. Cheap free float tubes, cheap Mossberg barrels, Delton bcg and trigger group. DSA blem lower with a Bcm-non ramped upper. Total investment for each gun, $600.00.

I won't buy anyone else's guns anymore. I prefer to roll my own.
