The Silent Industries MTW Alpha hop-up chamber - Inferno Engines is in stock right now in stock at Airsoftjunkiez... "The Phoenix Hop by our sister company, Invictus Manufacturing is our new CNC hop up for the MTW. Some features include:

• Improved Feeding
• Increased Durability and Wear
• Superior Air Seal
• Improved Groupings for a Variety of Setups
• Superior Full Auto Performance
• To get the most consistent pressure on the bucking through the hop-up settings, we had to include TDC. This means the nub can only move in up & down motion.

The TDC trolley we include is made for nubs, so you can use your desired nub."
