Good but not great - Midwest Industries MK2 RMR Cap

Like all Midwest Industries products that I have purchased in the past, the RMR Cap is of excellent quality. However, the height of the RMR base is quite low and is somewhat useless if the scope turrets are even medium height as the mounted RMR Red Dot is over 50% blocked. If your scope has low profile capped turrets, you might be fine, but for my setup, I ended up having to purchase on of the 10mm Reptilia ROF RMR Risers so that my mounted Red Dot was visible.

MI should either add height to the cap/base, offer different height options, or additional spacers to accommodate different turret dimensions.

So measure twice and buy once is my recommendation.
