New optic for my AR

[The Annoyed Man]

TAM,
Any issues with accuracay on the FastFire?

I ask because I have a very similar set up with a FastFire on top of my scope.

Being that high above the barrel, I am worried that the FastFire would be considerably off say at 5 yards and then 35 yards.

I havent had a chance to shoot this set up yet.

BTW, NICE set up!!

We didn't get the Fastfire dialed in very well yet. We were zeroing at 50 yards, and I can't even see the target well at that distance. It just looks like a blurry white rectangle to me—hence the need for a 5X optic. So I handed the rifle off to my son to see if he could do it. He struggled with it, partly because the elevation seemed to work backward of what was indicated by the arrow around the elevation screw. So I put off getting it dialed in until I go back there and try it at 25 yards. That's all I really need it for anyway, is for up close.

Also, I might try mounting the Fastfire on the side of the scope too. In order to see the red dot, I have to lift my chin pretty far up off the stock to look over the top of the scope, and it feels kind of unnatural up that high. And if that doesn't work for me, I'll get one of those 45º offset mounts to hang off my top rail. So it isn't really sorted out yet.....and it may not work for me. If it doesn't, that's OK. I paid a good price for it used but brand new from another member, so I'll probably sell it for that same price to someone else. That person will get a good price, and I won't lose any money.

Have you actually tried to use it at night? I tried several illuminated scopes, but the light was so bright that it washed out the target. The Eotech was the only one I found that actually could be dimmed enough to shoot at night. Of course, it was not magnified. And, I am shooting without any auxiliary lught source (just me and the moon).

I haven't shot it at night, but I've sighted through it. On the lowest setting, it's not bad at all. The lowest setting during day time doesn't really change the color of the reticle much at all; it still looks black.

What will be your intended primary range when you use this scope?

Chris, what will be your intended primary range when you use this scope?

Wow. It took me 4 months to see this question.

v-rog, if by range, you mean "place where I go shoot," I don't have any one place in mind....except to say that it would include hunting use as well as SD and recreational shooting.

If you mean "at what distance," I'm a believer in having a good zero and then knowing what the trajectory will do before and beyond that zero. Lately, I like the Santos Modified Battle Zero of 50 yards a lot, particularly for use in optics which lack some kind of ranging capability, because it gives a fairly flat trajectory all the way out to 250 yards, being less than 2" above or below POA out to that distance. The older 25 yard zero gives you additional range (range which I can't really use anyway), but at the price of a very high deviation in elevation. With the Santos Modified zero, you don't really have to calculate elevation—assuming your rifle to be a tackdriver. It's the lazy man's way of going about it, and I am lazy man. It also worked real well with my EOTech, which has a pretty basic reticle. Others like zeroing at other distances, with differing trajectories. My preference is based on an honest assessment of my eyesight. I don't have confidence that I can accurately hit a target beyond 250 yards with my eyesight, absent a substantial amount of magnification.

On the other hand, by not zeroing at 100 yards, I'm invalidating the built in bullet drop compensator in the reticle of this Burris optic. So at some point—which is a prefect excuse to go to the range—I'll take a couple of boxes of soft-tips to Elm Fork and re-zero for 100 yards. If I can get it zeroed at 100 yards, then the BDC will get me out to 600 yards........if I could see that far. Realistically, I can't. Not without a lot more magnification than 5X. Anyway, that's what I'll probably do: rezero for 100 yards.
