No problem. Remind me - U have the standard PS90 or the tri rail model? The TriRail, right?
Magparts has extended trirail siderails - but I don't know if they are just longer, or stick out far enough to clear an Eotech. You may want to ask Magparts in their subforum.
If not, a prev sponsor here - Crit Dimensions, sold side rails to replace the stock siderails on the trirail version. They were further out to work with an EOtech. I still have his contact info if you need it. He may still have a handful of these rails left to sell U a set. Send me a PM if the Magparts thing doesn't work for ya.
