in playing with the Charger, the vertical fore grip problem is probably a non issue... it is very easy to point... I shoot my rifles and shotguns with three fingers of my support hand rolled under the fore end, thumb over, and index finger pointing at target... with the heavy circular inner reticle of the Vortex Spitfire, that I don't really care for as it is pretty "busy" with my eye close, actually works very well when extended... at 25yd it covers the A zone of a USPSA target, and at 12 yd it covers the head... double taps as soon as the dot comes on target... I had a new range officer watching me very closely...kindly old man that I am
I did replace the polymer trigger group with an older aluminum version spare I built for the STC...
Bob... if you get the Charger, you really need to modify the bolt release by removing the detent peak, so you can release the bolt catch by just retracting the bolt handle slightly... there are some pretty good vids on youtube...
