I was kind of amazed, my friends and I were able to keep 50% of our shots in a 1 foot group at 100 yards with rifled slugs, WITHOUT a front sight! We had to hand cycle the rounds due to the gas block being open, but we had the slugs and were there to shoot them.
I'm going to figure out what size thread I'll need, and put a bead in for now. Then I'm immediately shopping for some better sights. Probably ghost ring.
Thanks, everyone, for the tips.
