Complete CNC steel bolt carrier set with Magnetic NPAS loading nozzle for WE V3 GBB M4

High-quality steel bolt carrier with a durable plastic nozzle equipped with the RA-TECH Magnetic NPAS system for WE Open Bolt V3 / WE AR V3 gas blowback rifles including M4 / M16 / HK416 / T91 platforms.

The bolt carrier is precision CNC machined from hardened steel. Due to its increased weight (260 g compared to approximately 200 g for the original bolt carrier), it provides a stronger recoil impulse and a more realistic shooting experience.

The Magnetic Locking NPAS (Negative Pressure Air System) nozzle allows adjustment of the rifle's power output. The patented RA-TECH magnetic locking system helps maintain stable settings even under heavy recoil and reduces unwanted NPAS adjustment movement during firing.

RA-TECH recommends using Maple Leaf hop-up buckings to improve air seal consistency and overall hop-up performance.

• Improved resistance against cooldown/freezing
• Lower gas consumption
• More consistent muzzle velocity
• Smoother BB feeding
• Adjustable muzzle velocity
• Patented RA-TECH magnetic locking system

The NPAS system allows the user to regulate how much gas is directed into the barrel and how much remains for the blowback system. Adjustment is performed using the included adjustment key inserted through the front of the nozzle. More gas directed into the barrel increases muzzle velocity but reduces blowback recoil. Lower power settings leave more gas available for the bolt movement and recoil effect.
