I've got no problem with peep sights. In fact, I consider them superior to all other types of iron sights. Sometimes I prefer them even to reflex sights or scopes. If they were truly that bad, then the US Military would've dropped them long ago. 1917 Enfield, Springfield 1903A3, M1 Garand, M1 Carbine, M2 Carbine, M-14 (all variants as well), M-16, M-16A1, A2, A3, and A4. Let's not forget the M-4 Carbine. Foreign rifles use them as well: FAL, FNC, G-3, CETME, G-36C, Enfield No.4 MkIII, FR-8. Countless commerical rifles have peep sights as well. Learn to use the peep sights- they're really great once you get the hang of them. Fast and accurate.
