Excellent product with some limitations - Trijicon RMR Dual Illuminated RM05 1x16 mm 9 MOA Reflex Sights

I have used Trijicon products for years and have never been disappointed. The ruggedness of the RMR is well documented and the limitations of the Dual Illumination model is as well. Having used similar style optics prior to this purchase I was well aware of the shortcomings. If you are not aware, these models have a tendency to wash out in transitional environments, most noticeably when in a darker area and aiming out towards a brighter area. The fix for this is simple, if using these on an M-4/AR-15 you just leave your backup irons in the upright position. In this manner when the reticle gets washed out, you just transition to the iron sights and continue to engage like normal. Problem solved. The same applies for use on a pistol or "tactical" shotgun. If you plan to use this on a firearm that does not allow for use of backup, then this may not work well for that application in the widest array of situations and you may want to consider picking up one of the battery powered models.
