Minimum mag you can use is 1x. One of my good friends used a 1-6x vortex LPVO with his Mate 50 (Dan from Gun-tec in shobdon Hereford) in regards to POI shift I’ll be filming a new video as I have just got a new QD style adapter system to attach it to my scope so will be able to show the grouping between multiple shots
I have gone up to around 14x mag and still found it comfortable to use. I have another video in progress on some new adapters for the mah50 so will also include going to max magnification on two different scopes 3.6-18 / 5-25 🤙
Any segment like that in any of my videos firearms are cleared safe no magazines inserted and firing pins are dropped so all is safe normally I state this in the video. If I’m shooting on any ranges or another setting bolts open and breach flag inserted. You are safe behind the screen don’t worry.
