Made of strong plastic, super light. One fixing allen key grub screw is included.
This sale is for charging handle with grub screw only.
Fitting instructions:
Put the handle in open position (around 45 degree, no need to pull it in full to the end) and fit the handle so that the grub screw is pointing inside. Pull the plastic handle towards the rear until it stops wobbling over the metal handle, this should make a snug fit. Fix it with the grub screw, avoid overtightening.
