Unfortunately I have not found an easy way to mount a scope on this rifle. The solution that I have been working on is a custom designed stock that positions the barrel of the rifle partially within the confines of the stock. allowing the scope to affixed to the stock without damaging the barrel of the rifle. I am trying to design the stock so that the breech is located near the butt of the stock, thereby shortening the overall length of the weapon without shortening the barrel itself.
(this involves designing a remote trigger mechanism that also has a safety lock.)
..It's a work in progress..
