The Flamingo NOIR is the heavy-duty variant of the popular Sniper Mechanics Flamingo hop-up bucking series, engineered specifically for high-power sniper setups, high-ROF builds, and Gas Blowback Rifles (GBBRs). Retaining the signature R-hop style concave internal patch geometry, the NOIR replaces standard silicone with a high-durability Nitrile Butadiene Rubber (NBR) compound to withstand aggressive GBB nozzle loading and high friction. The tough NBR material provides a tight air seal and superior tear resistance, though it requires a brief 100–150 round break-in period to seat properly into the chamber window.

Note: Designed exclusively for UNBRIDGED GBB/VSR-cut inner barrels (e.g., Action Army, Maple Leaf Crazy Jet, TNT, LayLax).
