A firing support hunting blind particularly adapted for use in an existing tree stand includes a firing support structure and a textile hunting blind assembly. The device attaches to the tree using a ratcheting mechanism being positioned above the tree stand above the base of the tree. The device supports a padded circular rail which acts as a safety barrier, supports a camouflage curtain which conceals the user, and provides a solid comfortable support for the users arms and/or a firearm during shooting. The various components of the device can be disassembled and transported.
