Yes, I've cheerfully used the 3x4 Kallax unit for records (and books) for a couple of years. All it needs (IMO) is an extra piece of material at the back of each cubicle to stop the records from going all the way in to the wall behind it - that's a little too deep for me. It doesn't let enough overhead light illuminate the spines, and it makes LPs awkward to insert among their brethren. It would be a lot easier if they were somewhere from a half-inch to an inch from the front edge. Someone on the webs makes a product like that, but it's insanely expensive compared to what I can cut in my shop from baltic birch plywood scraps.
