A buddy of mine made one out of a Williams rear sight ramp. He chucked a ramp in his 4 jaw on his lathe and turned it the bottom leaving a post of the proper size in the center of the ramp. He then milled the half round notch in the post for the lock stud in the base. Put a peep aperture on the ramp slider and viola! Fully adjustable and lightweight if not particularly beautiful.

He keeps it in a small tobacco pouch on the sling of his big bear rifle.
