Deep Fire 300 mm tight bore 6.02 mm

[KND]

I just bought one of those and plan to put on my SCAR-L, got it today and put it on SCAR-L perfectly but then the hop up didn't work.

First, I though I put it somehow wrong but after checking it and roll the wheel on hop up to see if the knot is working. Every thing are working but after put into my gun. The hop up is really doesn't work even I turn the wheel to the end and still no hop up at all.

So I put back my old stock inner barrel and test. Oh ! yeah, the hop up is working very good.

I'm just so curious why is that Deep Fire 300 mm tight bore 6.02 mm didn't work on my VFC SCAR-L hop up ?

I already try Mad bull but it's working good.

Any suggestion everybody ? or any solution about that ?

Thanks.

put your stock barrel side by side with the new tb. note any differences between the two besides length. look at the opening for the hopup and see that they are the same

Try cleaning the barrel with silicone oil, sometimes even when the barrel is new and clean it needs just a little bit of silicone to lube it up.

Just do regular barrel cleaning procedure don't just add lube.

Thanks man. I already did that step and clean my barrel before I put it in.

The hop up is really work when I look through the barrel and it didn't work when I put it into the gun. I'm really not sure why.
