Introducing the Shadow M4 grip! A newly designed ergonomic grip for HPA M4s! Custom colors available! Give your HPA powered M4 a unique flavor with this grip! Featuring a brand new, totally unique design with a bold, unusual yet awesome look. It's comfortable, feels different, works on all HPA M4s that use an AEG style grip. Great for Speedsoft builds or Milsim builds, the choice is yours. Other colors on my profile! If you want even more grippyness check out the stippled version on my profile! 🛑 Important Note: Will not work on GBBRs or AEGs due to the motor being present! This is an HPA product only!
