I've read many praises for the accuracy of the iron sights, and red-dots claim many other devotees. On the other hand, I haven't seen (or, at least, noticed) comments about the factory 4x. So: what do you think? Since your opinion likely hinges on the type of shooting you do as well as the environment, I'd appreciate comments and justifications in addition to a simple vote. My immediate needs: range shooting and occasional varmint control in mixed (wooded and open) areas, and I'm leaning toward irons -- most likely -- or the 4x. However, as this may be of larger interest and value, please let your imaginations and comments range widely for the benefit of others.
