The Blaster Barrel ID Key is a ready-made tool for performance tuning of foam dart “nerf” blasters. Featuring a step gauge design with a faux key-bow handle, this device measures an aluminum barrel's inner diameter, enabling reference to performance spreadsheets and estimation of performance from unknown spring and barrel combinations. Additionally, its small, flat design makes it portable, and multiple springs allow tuning on the field during games without color coding or tags that can wear off.
