Description Blue Nub for the Alpha Series hop-up chambers, basically an Omega nub on steroids! Why is it better than the current options? Same width as the hop-up window, no side to side wobble Better for mid and heavy weight BBs (0.32 ) Regular and Extended versions available Easier installation, you don’t need to center it Gives a bit more hop than ML Omega Precision molded Soft 70A silicone Easy on the bucking, won’t puncture it Works well with Stock and Phoenix chamber as well, when using our CNC ARM-X! Disclaimer: All aftermarket upgrade parts require necessary skill or modification to install and assemble, please consult with your airsoft technician if needed. This part is only for toys.
