Good shooting, by the way!!
Doesn't the Eotech window sit a bit high on the PS90? Seems it would be difficult to view, with cheek resting on the stock. I put the Vortex Sparc on our PS90 and, being a bit lower, sights great with "proper" cheek rest... but here I am talking and you are competing
We're all different and do what works in our own situations.
