    Hello,

    I have a Stag arms AR 15 carbine that I would like to add a Nikon Monarch 1-4x20 scope to. The more I researched the more I realize that the front sight post will likely be in the field of view at 1x power. However I have no idea how much it will be visible and if it will actually have any real world effect on my shooting.

    Are there any solutions to this problem other then removing the A2 front sight? Would a riser help significantly to get the axis of the scope higher then the front sight and therefore lessen the blur effect of the front sight?

    Any suggestions or even a picture of a 1x optic with the front sight blurred would be outstanding. I am just not sure if it will be a deal breaker and don't want to shell out the money for the glass if it is.

    You can't reeally see the front sight through a scope clear enough to make any differance.

    You may see it at 1x, but the scopes focal range at 4x will make it too close to even see it at all.

    In addition to what rcmodel said, a riser is probably a bad idea because it will put the scope up too high, which means poor if any cheekweld, and the funny POA/POI effects from having a very high height over bore.

    depending on your scope height, it may bother you a bit at lower powers. At 4x it shouldn't be a big deal.

    You can always ditch the factory front sight gas block, and get a flip-up front sight (either an integrated gasblock w/ flip sight, or a railed gas block and separate flip front sight like a Troy or Magpul). If you get a railed gas block, make sure its 'rail height'. Midwest Industries offers one that works, although its a bit heavy.

    I've got a big aperture sight in front and it is annoying to see the blurred image of it in my 1.5x sight picture. Past 4x or so its pretty much blurred out.

    You could get a thin profile competition front post, but even that will be visible at 1x. Short of removing the A2 sight or getting a riser you will never completely rid it from the scope, which is why I strongly dislike them for any kind of optic use.

    If it's likely to just be a slight blur and easy enough to ignore then that's good enough for me.

    I do have some experience with a scoped 20" AR15, at 2x the A2 front sight blurred out. Seeing as I already have the riser I'll just get the appropriate height rings and see what happens with and without.

    Thanks for the input guys.

    I run my carbine AR in Tactical Optics configuration. I'm using a Leupold CQ/T 1-4 x20. You do see the front sight on 1x, but you won't really notice it. At higher powers, you can't even see them.

    Keep the optic as low as you can comfortably mount it. It works much better that way, IMVHO. YMMV.

    I've got essentially the same scope on my AR. The FSB is visible, but not distracting. FWIW, I really like the combination. :D

    You can put a different front sight on it. Yankee-Hill makes a gas block with a flip-up front sight (three different styles). I have one on both of my ARs, and it works great.

    As an update, I received my 1-4 power Nikon scope. I have since discovered/confirmed at the lower magnifications it is quite necessary to get the axis of the scope above the A2 sight post in order to see the cross hairs of the scope. Therefore a high rise scope mount or a folding front sight is necessary.

    With a high rise scope mount you will see the sight post in the lower 1/3 or so of the scope but for me at least isn't distracting in the slightest bit.

    You typically want a magnified optic as close to the bore centerline as possible. I would go for the flip-up front sight. The Yankee-Hill part is $80 or so, and since you already have a set of rings, I think that's the smart purchase at this point.
