The SHS Aluminum Cylinder Head is a high-performance internal upgrade specifically engineered for the Tokyo Marui Next Generation Recoil Shock (NGRS) M4 series. Designed to replace the factory plastic component, this cylinder head provides the structural integrity needed to handle upgraded springs and high-stress recoil cycles. Key Features CNC-Machined Aluminum Construction Crafted from high-strength aluminum, this cylinder head eliminates the risk of cracking or warping under the heavy impact of the NGRS system's reciprocating weight. The rigid construction ensures that the nozzle remains perfectly centered, shot after shot. Enhanced Double O-Ring Seal To maximize compression and FPS consistency, the SHS unit is equipped with double rubber O-rings . This dual-seal design creates an airtight fit within the cylinder, preventing air leaks and ensuring that the maximum volume of air is pushed through the nozzle for improved range and accuracy. Integrated Impact Rubber Pad The rear of the cylinder head features a high-density rubber cushion. This pad absorbs the shock of the piston head's impact, reducing mechanical noise and protecting both the gearbox shell and the cylinder head from premature wear during rapid fire. NGRS Specific Geometry Unlike standard Version 2 cylinder heads, this unit is specifically contoured to fit the unique dimensions of the Tokyo Marui M4 Recoil Shock gearbox . It features the necessary offsets to clear the recoil linkage and ensure smooth operation of the proprietary NGRS tappet plate.
