Are there any that will let me keep my BUIS installed?

I run a T2 on my go-to rifle. During the day I have a magnifier in a FTS mount and a QD. It would be cool to throw my spare 14 on there with 3x magnifier, but I don’t want to have to remove my rear iron sight. Any way to do this?

The USGI one works with both the army issued Matech, and the KAC BUIS. You might have to play with where your optic and BUIS are mounted, but it works fine.

This is what I use with twist mount

Twist mount?

Can you fit a magnifier on the front of your 14?

I don't have one , so I can't say yes or no

But I do know with that twist mount... I can have it on my helmet, and within seconds have it on my rifle

I usually use it with a red dot and the PVS 14 behind it

FYI I have mentioned this already in two other threads, but I recently placed a PVS14 with a 3 magnifier behind a T-1 and it could not even be used. I subsequently learned from people here that the Aimpoints have a lens coating that makes it unworkable with the 3x lens. It is fine without the 3X lens but I found it useless without the magnification.

In a last ditch effort to make a compact NV system I picked up an Eotech EXPS3-0 and coupled it with the PVS14 and 3X magnifier. While the picture was great my Eotech showed the center dot to be a reverse comma. This issue does not really allow for accurate aiming. At this time I am not sure if it is my eyesight causing this reverse comma or the Eotech itself. With regards to the mount for the 14 I went with a LaRue flip to the side mount which I really like, but when used with the 3X it does not really leave a lot of room to fit a BUIS if you want proper eye relief with the 14.

You had recently mentioned the Eotech issue to me in one of the other threads but thereafter I found out that I have a slight eye issue. Naturally I wanted to rule my eyes out as a cause before I pitch a bitch to Eotech.  

One way to test your astigmatism is to look through the sight that looks funny, and rotate the sight  as you look through it.

If the abberations stay oriented the same way as you rotate, it's your eyes. If the abberations rotate with the optic, it's distortion within the optic.
