If I still had good eyes I would consider a peep sight. Most of my shots are like archery shots and a receiver sight would work great. As it is, I use a low power scope and sometimes a reflex sight (red dot). My ultra-slug 20 gauge with lightfield slugs is a one-shot marvel. Longest shot to date, 110 yards. I have won three club slug-shooting contests with this gun. I love it. Last year I was fortunate enough to harvest a 140 class buck. Shot it twice because after the first shot the buck just kept walking and I was not about to lose that bad boy. When I field dressed the deer I found the entry holes were about 1" apart. Other than that, since 2006 every year, every deer....one shot. It is the gun.
