Manufacturer: Modify
Material: Aircraft silicone
Compatibility: Marui spec products
Hardness: Two hardness options included in the set (Blue: 70 deg / Red: 80 deg)

Comments:  A set of two H-Nub spacers intended for replica tuning; it extends contact time of a BB with HU bucking, which results in a better and more stable spin.  It can be used in four directions depending on your preferences and is also as easy to modify if needed.
