WITH YOUR TIME AND EFFORT, AND THE PRICE OF THE CANTILEVER MOUNT, THE LABOR THE GUNSMITH WILL CHARGE YOU JUST MIGHT BE SPENDING SAME AMOUNT AS YOU WOULD A NEW GUN. LOOK INTO THE MOSSBERG 500 WITH A RIFLED/CANTLEVER BARREL, YOU BE SURPRISED AT HOW GOOD THEY SHOT AND NOT EXPENSIVE AS SOME MAY THINK. JUST GIVEN YOU ANOTHER CHOICE, GOOD LUCK
