The 
NUPROL Black-Out Holster NX300 (EU7)
 is a specialized polymer holster designed specifically for EU Series Airsoft replicas (such as Glock-style pistols) that are fitted with an NX300 series pistol torch. 
 
Key Features
"Black-Out" Design: Features a polymer end-cap designed to hide light or reflections from the mounted NX300 torch when the pistol is holstered.
Quick Detach System: Allows for easy removal of the holster unit from its mounting platform.
Mounting Options: Typically supplied with a belt loop adapter for waistline fitment (compatible with belts up to 50mm). It is often compatible with other NUPROL "Perfect Fit" accessories like MOLLE adapters and drop-leg platforms.
Adjustable Retention: Uses closing screws to tune the friction-based hold for a secure but accessible draw.
Material: Constructed from durable, semi-rigid Kydex or law-enforcement grade polymer depending on the specific sub-model variant.
