Hello, I am Rusty Gray, US Army Veteran, and inventor of the AR15-cup Handle. I use one every day and it just feels right in the hand.
If you like what you see, feel free to email and inquire about a purchase, or better for me, carrying the handle in your store or on your web site.
I designed the ring part and I use genuine A2 grips. You will have to buy your own cup. For now that is.
Thank you for stopping by and please feel free to leave feedback and comments and suggestions.
