Here's a picture of the mount attached to my wheelchair. It is not attached like it is supposed to be because my electric wheelchair would not allow it. Had to do some modifications. Every wheelchair is different, so you will have to find what works for you. This rifle is my Remington .243 Model 7400.
This is another picture close-up. This is before I had the trigger that I use now. This was first time shooting rifle after my accident and first time using this rifle mount. This is just an old .22.
