Buy the bracket, it is nice if you want to reload for a second shot quick with one hand. I have collected more than 10 of them over the years. I don't like spending a lot of time setting up in the dark unless I am in my climber.

I bought an extra bracket and have it attached to my climber. I have strapped it to the tree in the past.
