Hello. In regards the Nova Freedom PCP rifle and it's sibling Air Venturi Seneca Aspen, will owners or users answer this question please? Does the barrel shroud have baffles or insulation inside for the purpose of silencing the gun? By design, does propellant air vent in any fashion into the shroud or elsewhere for the purpose of silencing the gun? Does the actual rifled barrel vent propellant gas at any place from breech to muzzle? I'll reveal the reason for my interest upon considering your replies! Thanks in advance.
