Separate your upper from your lower. Remove your charging handle and bolt carrier group from the upper. Put a factory round in the barrel and lightly tap the back of the cartridge with a finger into the chamber. Point the barrel up and the cartridge should fall free. If it sticks, you have a chamber or throat problem..A function gauge works best, "but in a pinch" using a well made factory round will work....
