DSBFABRICATION TUNER F/Open

This tuner offers another option.  I did not want to take the muzzle of my barrel down to 0.850 so I created a tuner that more suited my needs.  Thread diameter is 1.125, and fine adjustments are no problem with a thread pitch of 32 TPI.  No set screws to deal with, an internal O-Ring provides plenty of friction to keep it where you set it.
