Silent Industries Blue Nub for Alpha Chamber (Soft) ZB2U QD points for simple slingBlue 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 dont need to center it Gives a bit more hop than ML Omega Precision molded Soft 70A silicone Easy on the bucking, wont puncture it Works well with Stock and
