Ameriglo is a great brand but I've had the front sight fall off after high round counts with these sights, even after having them installed by a gunsmith and properly torqued, Locktited etc. I wish they offered a slightly lower height version so it only barely co-witnessed above the deck of an RMR or equivalent optic. Would probably have gone with Dawson Precision or Continuous Precision options instead. I think these are the best option if you're using iron sights and shooting with a suppressor, but there are better ones out there if the goal is RDS backups.
