Need help correcting my byf 44 barrel bands

[1armybrat]

Looking to put the correct barrel bands and spring on my byf 44. Looks like an i block. These byf 45 bands will be avalible to some one that needs them when I switch them out .
Looking to confirm that the byf 44 i block bands were unnumbered as well.
Thanks in advance.

You have an L block, would have unnumbered bands.
