The arrows are Easton Full Metal Jacket Dangerous Game arrows. I have some of those same shafts and with fletches that look almost the same. Mine weigh in at 844 grains with a 150 grain BH and nocturnal nocks, so those are probably very similar to mine and likely within an inch of the overall length. His do not have the nocturnal nocks. My guess would be 250 spine on the arows and 31" long.
