Product details

We already know the VSR Panthera Nub is a widely used popular nub in the VSR community so we designed the Panthera Fat Concave Nub to fit other hop up chambers like the Stalker Kraken S3 arm but also the AAP-01 pistol Wheel adjustable CNC chamber. This Panthera Fat Nub will probably fit many more chambers as well.

The shapes and measurements of this nub are designed to work best with VSR Style buckings such as Kraken Concave Bucking, Maple leaf Autobot/ Decepticon, etc. or AEG buckings that have an inner patch of approx 5mm.
