Magpul MIAD grips are my favorite and I have them on my two carbines.
You could change the backstraps or frontstraps to adjust to the size of your hand or use the smaller size when wearing gloves.
There are different center cores that could hold cartriges, bolt, batteries, etc.
They're available in three colors, black, olive drab and coyote brown.
