$299 for both the carrier and the kangaroo pouch triple magazine insert.
If you click around on the size and color options and reload the page you can sometimes get certain combinations to say In Stock after previously saying Sold Out. So their website may be glitchy.
Just remember that whether it says In Stock or Sold Out, that's for whatever product code is listed right above where the $299 price tag is listed, not necessarily for whatever color is shown on the image or whatever options you have selected in the drop down menu.
So if the picture is of a grey carrier and you have "MAS Grey" selected, but the item title above the price tag says "LBT-6094A-KIT-M5 MULTICAM", then the stock status displayed is for a medium multicam regardless of what color or size you currently have selected in the dropdown menu.
