Stop Fighting With Stubborn Mainsprings

Specially designed tool shortens the time and eliminates the frustration that goes along with changing mainsprings in double barrel shotguns. Notched, blade tip captures the plunger head so you can compress the spring and lift both parts free from the receiver. No more scratching and gouging the plunger or inner receiver surfaces with an ordinary screwdriver. Tool works equally well for installation – simply seat the end of the mainspring in the receiver, hook the blade notch around the plunger head, compress the spring, and engage the plunger in the hammer. Stout, hardened steel shank provides plenty of leverage and keeps you close to your work for maximum control.
