I'm thinking of getting a Choate Tactical stock for one or more 12FV's. Im almost sure I wont like that open track/channel, running along bottom of handguard. Anyone have any ideas, how that track can be filled w/ something, or I'm quite handy in the metal/weld field. I do want a lug in front for a bipod, but dont want it sliding/adjustable. Also, the grip looks very fat, and maybe some other parts of stock may feel bulky too, I'm not sure, cuz I only seen the in pictures. So, any ideas on removing some of that material, and be able to make look stock half descent afterward? I was thinking belt sander, or a emery type flap wheel on a 4 1/2" grinder or something. thanks
