The Dead Air Xeno Xero in 9/16-24 RH (Dead Air part no. DA143) is a threaded taper mount that gives you a lightweight, minimalist mounting option with a solid return to zero. Dead Air Silencers cut the short taper to sit shallow in the blast chamber, which maximizes sound performance and holds down weight. It is compatible with all Dead Air Xeno adapters. This 9/16-24 RH version has a 9mm bore, sized to fit 9mm and smaller projectiles.
