My 10 yr old Browning Mirage w/80# draw wt. Use to sound like a tank's turrent recoiling after a shot, lol. But the bow has kept me in a high success rate with Roosevelt Elk. So i have put time into silencing this mechanical beast. 1st for increase of speed & silence on the draw, I installed a "Arch Rival" combo overdraw/arrow rest (Great product). Limb Savers made quite the reduction in vibration, Doinker stablizer has also eliminated vibration, although my buddies mock it's appearance. The biggest noise reduction i encountered was, eliminating my Fine Line sights. The wire for these sites sings a very high pitched tune when your draw weight is up there. Speed balls also helped string noise. Removed tubing for peep sight.
This old bow is shooting at 268-272 fps.
