Is the barrel made of steel or pot-metal? I'm considering to buy it, and I'd love to fit a PBS 1 to it. I'd also love to buy a steel PBS 1, but I don't think a pot-metal outer barrel would like that...

to be safe an aluminum or any lightweight PBS1 replica is recommended.. i dont know if the barrel is made of steel of pot metal.. but if the front sight is pot metal you cant use a steel PBS1.. its so heavy

For the KLS price , i do not bother much about steel/zamac parts .We have played so far with Aluminium /Zamac since Marui and if we care no problem with
Even some parts are fragile , alas not in steel and exposed :Front sight visor , gaz block which can break on the KLS/BOYI , except that it is OK

Do not forget that if you PBS silencer to long or heavy it can break easily the front sight visor thread ...
