The TMB tuner delete jam nut is a compact, lightweight and sleek looking locking nut for the TMB muzzle brake. You can substitute the original TMB jam nut for the tuner delete jam nut to remove the tuner and save weight or streamline the look of your rifle, allowing you to run the muzzle brake only, without the tuner.
For installation or removal you use your standard TMB wrench or you can purchase the new style TMB wrench (sold separately), no added tooling required.
