scope ?'s, anyone use the Nikon "M" AR scopes
I just picked up a DPMS LR 308 and was planning on putting my scope from my varminter RRA (Vortex Viper 6.5-20X50) on it, but now I am torn about just buying the Nikon M223 and M308 in 4-16. They both already have a ballistic turret on them (which I would have put anyway so it saves me some coin) and would be almost exactly alike so easy to transition.
Anyone used these? Otherwise it is likely a Viper PST for both guns as I have experience with Vortex and like them (and get a great price).
Also: bonus question, are the "M" series Monarchs?
