RIFLE BUTTONS

Rifling Buttons are Precision Carbide Tools for forming the rifling grooves and resizing the bore in gun barrels. Sizes range from 14 caliber Rifles to 10 gauge rifled shotgun barrels and can be ground with any helical twist right or left handed. They are available in rifle only, bore only, or combination style. The Buttons are either Push or Pulled through the barrel depending on the type of equipment you have available. We also recommend all rifle buttons to be coated with either (TIN) Titanium-Nitrate or a (TIALN / Futura Nano) Titanium Aluminum Nitrate coating. This will improve your tool life and increase barrel finish by keeping the material from cold welding to the buttons.

All these buttons are made to your specifications or we can determine the size of the button based on material, hardness and wall thickness of the blank. To achieve the correct size button all these variables must be determined for the expansion and contraction during the buttoning process. If you plan to stress relieve the barrel after rifling this also needs to be evaluated into the equation.

Once you determine the style of Rifle Button you wish to use you need to determine the exact size of the Rifling and Bore you wish to establish in the barrel. You need to first start with a good straight gun drill hole approximately .006”-.008” smaller than your Bore size. Then pass a reamer through the barrel to establish your Bore size to remove any surface imperfections and control the inside diameter of the barrel from one end to the other.

Then you are ready to Push or Pull your button through the barrel. Utilizing a good pressure lube is required to achieve good results. The process is very fast, approximately 40”-60” per minute. A combination button which consists of a rifling button and a Bore button will both swage the lands in the barrel and resize the bore section in one pass.
