Oh god it's another cursed abomination from gunnitrust.
This isn't the first time I've seen it today, and if it wasn't made by AI I have to assume someone crafted the original image, giggling to themselves as they put so many features that don't mesh into it, while also seeming like it could.
Honestly it almost looks like a Bren 805, but something doesn't quite look right about the receiver. Like it's a high receiver from an AR platform, but everything else looks like an 805.
Ive been wanting to get a 308 for awhile since most of my stuff is pistol caliber or 556. Awhile back I almost got a coworkers dad to sell me his FAL, but then the day before the exchange he decided he wanted to keep it. Ah well.
The obvious choice is to buy a multi-piece rifle, full size or pcc is up to you, that breaks into 2+ pieces.
Have your pet carriers modified to carry the pieces and some utility things like ammo/cleaning/batteries/etc.
Now when you load up your pets, you also have your carry gun!
No part of this was thought out for practicality, results may vary from intent.
Arm your kitties.
