Hello,

The MP5 has a standard barrel length of 225mm.

But if you add the flash supressor below:



How long does that supressor make the overall length of the barrel when permanently attached? Because I need a total barrel length of 300mm to legally
own this weapon.

Thank you!

I own a SP89 clone and that FH. I did a rough measurement and it will add approximately 31.75mm to the barrel length.

I took a drinking straw, I don't have any dowels, and put it down the barrel with the bolt closed. I marked the end of the barrel and then put the FH on and repeated the process. I then measured the difference.

I hope this helps.

That is great! Thank you very much. Can you also measure the length of the flashider itself? Thank for the help.

Anytime, that is why we are here.

Out of curiosity, are you allowed the full auto versions or are you limited to semi-auto?

You understand an MP5 and SP89 are different guns altogether, right? SP89 measurements are of no use for an MP5 build. We're talking the difference between and MP5k and a standard MP5.

I am not sure if you ment that for me or the OP.
I am aware of the difference, which is why I stated which platform I had. The length of the FH will not differ between the two and the OP stated he had a barrel measurement and needed the FH measurement.
