Slightly longer but shouldn't go past the flash hider.

Would it fit my hop up unit and is a 6.03 more usable than a 6.01 ?

Er, 455mm is the length man not the width (if that's what you mean) so it wouldn't effect the hop compatibility. If you mean 'will the hop window be compatible' then yes, it is. It'll stick out the end by 15mm but like Monty says, but that's not a problem as the flash hider will conceal it.

 

6.01 will give you a negligible FPS increase, but a wider bore will give you better accuracy and allow a more consistent hop. If you're happy with the FPS of your stock one then go with the 6.03. Also, it'll be slightly less prone to jams.

Yeah the barrel length is 440mm I've found a tight bore with 445mm but it's for ak's would there be any fitting issues in a we msk ?

Most AEG barrels are listed as being for a specific gun based on their length, the hop-up end is usually the same
