The RA-TECH NPAS Complete Carrier Set, is a upgrade set for the bolt and nozzles of GHK M4 v3. Made of CNC Steel and heat treated, the bolt is more resilient and durable than the stock bolt, thanks to its CNC milling and heat treatment. As a set, this kit comes with the RA-TECH NPAS nozzle, a device that adjusts the muzzle velocity on the fly to meet field velocity requirements or adapt to changes in temperature and weather conditions. Featuring RA-TECH patented magnetic locking system, the NPAS nozzle can be adjusted with the Type 3 universal screwdriver without disassembling the gun, making this a convenient upgrade for shooters that play with various muzzle velocities. In addition, the RA-TECH nozzle provides better gas consumption efficiency, better freeze resistance during prolonged use, consistent muzzle velocity and smoother feeding of BBs.
This product comes with the RA-TECH Type 3 Universal Screwdriver to adjust the muzzle velocity output. If already have the tool and don't require it, you can buy the RA-TECH Complete Bolt Barrier Set with NPAS for GHK M4 V3 without the tool here!
