The RPR is my primary hunting rifle.
I love it except for one issue: I am left handed and if I sling the rifle as such the bolt stabs me in the back.
To get around this I designed a slim bolt handle that rests cleanly against the body. This also helps to keep the bolt in the down position and avoids snags.

Feel free to use the design as a base for making your own bolt handles, I attached a base model that can be used for such.
