No, it's not. Most grain bills for making beer include gluten-containing grains including barley and/or wheat. And malt syrup is made from barley as well, so it is not gluten-free. To make it gluten-free, you'd have to leave out the spent grains and use gluten-free rolled oats and/or other non-gluten containing flakes and ingredients such as hemp hearts, rolled amaranth, or rolled quinoa in place of the spent grains. And use honey or maple syrup in place of the malt syrup. Make sure all other ingredients are gluten-free as well.
