So looking at some pictures and videos of the "updated" model, it looks like there is a few different variants floating around or something. Maybe some are old stock that were retrofitted, and some are completely new stock?
For example looking at black and desert storm versions on the barn here (ignore the marine it's the old version):
https://www.thebarn.net.au/categories/Berika/17141The black variant has a keymod forend, as well as a small section of pic rail on all four sides. Whereas the desert version has an M-lok forend, and only a single pic rail section on the top, and seemingly a completely empty flat bottom section of the forend.
Not that I would need to attach a bunch of accessories to a shotgun, but there would be a significant difference in the way you could attach a flashlight, or a sling point etc... between the two versions.
It's a similar story with other sites/vidoes that have the new model shown as well. Some of them show the m-lok version, and others show the keymod with the extra pic rails.
