ARMS 40 BUIS thoughts and answers?

[Dennis in MA]

I've got a std one I've never mounted on a flattop. I've GOT a flattop, and working on one or two more (don't ask) but I see on the Bushy site that you need a higher front post. Yes? No? HAven't read that anywhere else I believe. (Granted, I haven't read the instructions that came with it in 2 years - I let a buddy take a look at it - I'm getting it back on Saturday. LOL)

On the ARMS website, they talk about the difference between the 40 and the 40 low-profile. Something about the zero's being different between the two apetures? I have no idea what they mean.

I'm hoping someone can explain in english what they all mean. And has anyone TRIED the low-profile one? I would think it would be more out-of-the way in a "get banged up if it sticks up too much while folded" sorta way.

Thanks for any primers on this sight. I'm just confused at this point. :)

I took a M4gery barrel off a A2 upper and put it on a A3 upper with a ARMS 40A, and the elevation changed a whole two clicks. It certainly didn't need a new front sight post, not on mine at least.

I have the ARMS 40 BUIS on my A3 Stag upper with a standard front sight post, no issues.

Well shuck my jive.

What about the zero between the large and small apeture? Mine LOOKS the same. Anyone tested that? (I'm sure it's the same and I read it wrong - I think.)

My zero didn't change as far as I could tell from the small to the large aperature.

Got to finger the low-pro version today. I like the full-sized better. And I saw how the lo-pro one has different zero's. Small aperture is definitely higher than the big aperture.

My problems are solved - maybe. LOL
