Tomac was nice enough to let me borrow is RX30 - I am so used to an Eotech on my PS90 - that I just can't get used to a single dot (like the RX30 or an Aimpoint). For me, it takes longer to find, and I tend to move it more in CQC than I do with the larger EOtech reticle.
Anyway - I think I will buy another EOtech for my MSAR - just a matter of the XPS or a 512/517 model. The XPS reportedly will co witnesses exactly - does the 512 cowitness exactly too, or does it 1/3 co witness. I did see that the 517 does the 1/3 cowitness - but apparently this is because of a built in riser. So, that should put the 512 and the XPS at the exact same height, correct? I found the stock MSAR optic to sit too low for me. I don't want to have the same issue if the XPS sits lower than a standard EOtech.... |

The 512 will not cowitness 1/3 unless you get a riser. As for the XPS I "think" that they will not 1/3 cowitness. I may be wrong as I have not used one yet.
I have the 512 on mine. It's the standard height top rail. I have the E4 top rail on order as I have to raise my head a bit too much to get the circle-n-dot into view with the standard STG rail. |

Ok, thanks for the info. I guess I am just used to the higher optic on the PS90.
I ordered some Magpul back up sights - now I just have to figure out which EOtech I want. I am not happy with the 511 battery life that I already have - so I know I'll have to go a different route. The new XPS may be less likely to drain the batteries when off like the older models - is what I am thinking. But, AA batteries ARE more common (512 model) |

Video link showing the new EOTech EXPS. Very cool.
