The following is my gear test report for the DIABLO rifle case and shooting mat.
In Fig 1. photo I found the need for a sleeve for the buckle. This sleeve could be made out of a elastic material to make it easier to access the buckle but at the same time give a non scratching surface that comes into contact with the rifle when folded. I know the buckle is just plastic but over time I could see this rubbing and causing damage. Also notice how long the straps for the mat are. Having just some hook and loop sewn to the end so extra strap could be rolled and secured would be a great feature and function to keep the straps at a desired setting.
In Fig 2. Adding a row of additional molle would allow for add on's to be mounted lower into the case I found somethings wanted to stick out no matter what I did.
Lastly Fig 3. Shows alternative points to consider moving shoulder strap mounts. I find the current placement very effective and allows for a very comfortable shoulder carry but when used as a shooting mat they are in a very bad place. The hardware I can see becoming damage if used on very hard terrain. By relocating these straps to the proposed area it still serves the same function but also should get these out of the hazard area.
