Gracias mate.Yes, there are 2 different versions. The one for the 10.4” barrel has a 1mm vent, and the adjustable regulator has a 1.6mm port for unsuppressed shooting and a 1.4mm port for suppressed shooting. The 14.5”/16” barrel version has a 1.5mm vent, and the adjustable regulator has a 1.4mm port for unsuppressed shooting, and a 1.2mm port for suppressed shooting.
I know, you’re always right regardless.
Carry on, it’s all yours.
