Airsoft rifle modular wall mount brackets

As I couldn't find any decent wall mount brackets I decided to mock one up for both my rifles and my pistols.

These rifle brackets have a slot on them to design and mount different attachments to suit the rifle you aim to place on them. My Specna does not need any attachments but due to the weight, I made 2 of the fronts and 1 back for extra support.

For the Honey badger, I am using the attachment in the front mount and the rear as is.

Any attachments required, to a drawing in detail and I'll be happy to make them as they take only a couple of minutes to do.
