Wait, what? I don’t understand, in the picture it shows the charging handle on the left side. If you shoot right handed how can charge your weapon with the left hand without taking it off the forearm?
Assuming you’re using your right hand to hold the rifle by the pistol grip. You would insert a magazine with left hand, then reach back with same to pull the charging handle back.
I always charge left handed anyway. It really doesn’t change that. If you shoot right handed you charge lefty.
