I would like to get a 16 1/4 " barrel to go with a contender folding stock for and extra hunting rifle to leave in the truck. Thinking of 44 mag or 30-30. The odd part is I want it drilled and tapped on the bottom of the barrel to mount a laser on a weaver mount. Is their an easier way to have a scope and laser combo. Also who makes custom barrels? I know of fox ridge and eabco are their any others. any ideas?
