i know it's preference and im probably overthinking stuff but i got a new mk-12 upper coming from high caliber. and a good early 90's preban gov/leo bushmaster lower. im thinking of having them cerekoted a solid color and hitting them with different colors of krylon from time to time. i love fucking with camo. i know terrain has every thing to do with color choice. but what would be the most versatile base color fde,od green,or other green, grey,black ive been thinking about a flat grey. seems like grey is the constant in most all seasons in most all terrain. just good fun thanks to all.
