Looking for some info on scoping an Armalite AR50. After some research, I have noticed some people saying that too low of rings will not allow you to remove the bolt completely. Anyone know how low of rings will work? The factory base is very tall and bell clearance wouldn't be an issue, even on a 56mm. Won't have the rifle until next week but would like to order some rings. Probably going to try a Viper PST on it and Seekins rings. Any suggestions?
