Short Bit Chip
Short, single-sided Bit Chip. Requires a Bit Chip Cover, resulting in a heavier overall bit chip. This will very slightly reduce your stamina versus a long bit chip, and they're more prone to dislodging, and become unusable if the tiny, fragile inner prongs on the AR snap off.
Nonetheless, they do add an extra amount of centred weight to a combination, thus are technically a good choice for Compacts and other defensive or weight focussed setups.
Has a propensity for the bit chip cover to pop out on one side after strong hits and send the bit chip inside flying, which was part of the move to Long Bit Chips (which also reduce production cost).
