Make mismatched hardware configurations work together seamlessly and expand the tactical reach of your rig setup with this premium 18.8mm Female to 18.8mm Female Glass Adapter. This boutique converter is the definitive choice for the enthusiast who values a high-intensity ritual combined with the absolute freedom of modular multi-brand glass connectivity.
