Sounds good. I didn't buy the ring I just cut the grooves so the turret rotates 360. I used the HL Ultimate edition gearboxes. Metal wheels are ok, but add weight. I changed to the metal sprockets that's all.
I too am from the coast of Virginia. I just got my M1A2 and looking to do necessary upgrades. I'm wanting to do the 360 turret ring, metal wheels and steel gears rather than the alloy gears that came with my HL.
