Buying outer barrel extenders for longer inner barel

Hi guys,

Im looking at getting x2 bruise master barrels, 35cm and 40cm for different ■■■■.
But i dont want the bare inner barrel sticking out and prone to impact.
So my Q is: where can i get barrel extenders from? for more specifically to fit that length.
(every shop in aus is sold out currently)

Do i need to measure the inner diameter of the current J10 and HK416 to know the exact inner width specs and also get reversed thread so can fix on?


“Hell yeah” I think have them
