There were kids riding 4-wheelers where I planned to shoot so since i had a few hours to kill I took everything apart, soaked it in mineral spirits, scrubbed it all with a brass brush, oiled it up and put it all back together. A good exercise to familiarize myself with my new gun. Then I went out and shot 150 rounds with the intent of zero'ing in the iron sights. I never adjusted them once - I could hit a beer can 50% of the time from 50 yards, and I'm not a very good shot. What a joy to shoot. The iron sights that come with the gun are so easy to use that I can only imagine a red dot is useful in the case that SHTF and you need to acquire targets fast. I love this gun, can't believe it took me so long to get one.
