This TDC hopup adjustment tool was made in collaboration with Project Airsoft. It allows for easy adjustment for any SSX23 / MK23 TDC cover. This tool can be attached to the threads located on the trigger guard (originally designed for the LAM unit) when not in use. Opposed to the original, this one is fully compatible with DTD holsters! The tool is made out of steel with a black oxide coating for maximum durability.
