Mossberg 500 HD
The ATP is from the early 80s, and likely saw a lot of time in police cruisers. Now it sits in my safe.
The HD (Home Defense) is a new model 500 that uses the “old style” forend, action bars and slide tube. Everything has a matte black finish, including the bolt. It also comes standard with a reduced LOP stock. The forend is Blackhawk! With a magpul rail attached for the flashlight. The HD is also notably heavier than the ATP.
