Deletion of Shooting arm sleeve

Comment: I'm not finding any reliable references for this, mostly sites trying to sell them, and I don't see that this is notable enough to be covered. "Target for advertisement" isn't a reason for deletion in itself, but there's not enough context to maintain an encyclopedic article on this. Maybe redirect if an appropriate target can be found, but I see no reason for this to remain without some |significant work
