Yes. Even with a magnifier it still subtends 4 MOA. It's just that the magnification turns it into a 4 MOA comma-shaped blob. It works OK on my Aimpoint PRO, and with my Eotechs.
The ARMS mount on my FTS has held up just fine. I have no complaints.

For magnifier use, I liked the Eotech better. For me, the reticle looked much better when magnified.
The coma effect is more than likely a result of your vision. You can easily test this by taking a picture of the reticle. Cameras don't have astigmatism.
I was told the new EOTech magnifier mount is not spring loaded, any confirmation of that?
So, what's the difference between a $150 3x magnifier and a $600 one? Are they three times as good or what?
I mean 3x is good for long range, but with a removable or flip to the side mount for the mag, reliability is not a killer factor, just an inconvenience.
The new one is only $150?
