Optic use on AR-15 with front sight post

[Bill2905]

I want to put an optic on this Colt carbine. Was thinking something like a 1x-6x for 50-200 yd shooting. Will I have any problems with the front sight interfering with my view?

I use a Larue QT mount on mine with no issues

They have different heights available

I have never seen a problem. At that focal length the scope really cannot see the post.

On low power you might see the FSP, blurry, in the bottom 1/3rd of your view. It won't interfere with the scope but personally I found it kind of annoying.

3x and above it should disappear.

no

Thanks for the replies. Now I just gotta figure out which optic to get. That could be a whole other thread in itself.

It certainly could, though there's gonna be a bunch out there already!
What you'll discover in all of them is that for useful recommendations to pour forth...

We, the Internet, need to know:

• your use for this optic/rifle (distances & target-types)
• your expected budget.

Something I learned the hard way. More power is not always better. Unless you are shooting heavy bench rest, too much magnification holds you back. At 1000 yard prone matches, even a $1300 24X benchrest scope does not work. It magnifies every body movement, including your heart beat. You will lay there with perfect form and get seasick. Been there done that.

I shot the same scores with iron sights at 1000 that I shot with a scope. (good irons, like $700/set) I ended up with a good quality 6X target grade scope. I also had a 10X target scope, but even that was a little too much.

It is my opinion that a Good quality 3X scope will do fine for even a top grade AR. I know bench guys use way bigger scopes, but I never heard of Uncle Sam issuing shooting benches.

That's why I was thinking 1-6X. I do a lot of bench shooting for groups with bolt guns and own several variable high power scopes. However, I try to achieve my goals using the middle of the magnification range because of the issues mentioned above.

just use a 3/4" riser block and have fun shooting!!

I'll second the Larue QT mount as I have the exact same issue and was worrying about seeing the front sight post at low powers, which I don't.

 

[JSJamboree]

1-6 PA scope can you can see the sight post in the very low mag range, but higher up its not visible.

 

[Robert Richardson]

Not really something to worry about.

The highest ive run afield is 12x and that off a Harris bipod. Reg varmint rifles to 450 yards.

Have run fixed and variables.

3-9x, 3.5-10x or 4-12x......theyre either cranked all the way up, or all the way down.

For a non bipod rifle a 2-7x is pretty nice. But thats old school. They have stuff that goes beyond 3 times power in range now.

Have a 2-7x on a deer rifle and i can see the front sight at 2x. I run it as a 3-7x LOL

Could remove my sight but leaving it on means less chance of losing it

 

[Hookeye]

F&S did a study some time back, a test really and most folks did better from field positions w scopes maxd around 6x.

I would agree as more mag makes more wobble visible. Too many fight the wobble, makes things worse.

But if shooting 100 from a bench id run something up to 12x.
