So I have the MDT ACC in a curtis axiom, area 419 hellfire, MPA one piece mount with a rds top rail, NF ATACR 7-35. I'm having crazy balance issues. I currently have the aluminum bag rider on the rear, and 4 out of 5 interior weights in the front, with an empty slot closest to where the break is. Balance seems to be 2-3 inches in front of the mag well, and I can't seem to understand how I see people with ACC's using 2-3 exterior weights and i'm assuming some interior weights as well. I have an order placed for the rear buttstock weight which should help out, but I'd like to be able to get my gun heavier. Anyone else having problems with this same setup?
