I purchased a Bushnell TRS-25 Red Dot, and first mounted it towards the front of the factory rail about centered over the magazine of my PLR-16. This seems to work fine, but renders the rear iron sight useless. The TRS-25 has a little deal on the bottom right corner that prevents cowitness (noob to these type of sights, but I understand that to mean that in the event the battery is out or whatever, you can still shoot just fine using the irons). I found however, that if I mount the red dot in place of the rear iron sight at the very back of the rail, and relocate the rear iron to the front of the rail, the irons can be very easily seen through the glass. This would also seem to make the gun less nose heavy. Can someone explain why this is a good or stupid idea? This is the sight picture, sorry the dot was turned off: PS: As a homebody, my TRS-25 is not likely to get damaged or run out of battery, so should I even bother with having backup irons and just pull em off? Thoughts?
