  1. So, say you have a fixed front post gas block; What rear sights or reflex sights would you recommend for a setup including that? I've been having difficulties finding suitable options where the cowitness is absolute.

  2. I'm torn between co-witness and lower 1/3 for my MRO on my home defense rifle, I know it depends on each facial structure and personal preference but which do you choose and why? @Mrgunsngear

  3. i cant see anything with my rear sight flipped up!! i have to tilt my head sideways just to see the front sight with my rear cranked all the way left! any body tell me what im doing wrong? should i move my rear sight up some? have A2 front sight flip up back,ruger 556

  4. Another good video my friend, im doing a ar build, 20 inch pre ban heavy barrel with f marked front sight base, a3 flat top upper with t marks, how many of the flip up rear sights will work with this setup? just a backup plan for my scope, varmint rifle, 5.56, Thank You and God Bless America
