Unlike traditional iron sights that utilize a front post that obscures the target, the Guard D Front Sight is an aperature that lets the user see their point of aim much more clearly. When properly aligned, the front peep sight-style globe and the "goal post" rear notch sight form an arch like a capital letter D on its side.
This combination allows the user to not only better identity the target through this peep window, but also easily acquire the target up to 20% faster according to company lab tests.
This is a front sight only. For best results, pair with a OEM 6.5 rear sight. Not compatible with G42/G43.
