While Tokyo Marui's newer large-bore GBB pistols (such as the G17 Gen.4 and G19) provide a harder kick, they are also more susceptible to pressure loss when the large cylinder chills down under rapid fire. The MEC R-Type Marui-15 is specifically dimensioned to seal these modern, high-volume nozzles. Machined from premium brass at 2.0g, this unit adds structural stability and uses an advanced 6-hole air port configuration to deliver faster compression and snappy reset.

Key Features & Benefits
  • Optimised for Large Nozzles: Solid brass construction handles the heightened impact of TM's large-diameter blowback housing without edge warping.
  • High-Volume 6-Port Inlets: Speeds up air redirection into the seal groove, forcing the O-ring to seat tightly against the internal nozzle walls instantly.
  • Precision Fitment Kit: Includes three targeted O-ring profiles (red, black, green) to ensure an airtight match with either OEM or aftermarket upgrade nozzles.
Technical Highlights
  • Weight: 2.0g
  • Materials: CNC-Cut Brass, Industrial Rubber
  • Compatibility: TM G17 Gen.4, G19, PX4, FN 5-7
Applications
  • CQB & Rapid Target Engagement: Maintains full slide travel and reliable lock-back on empty, even under cold conditions.
