Solving the Problems of the Prior Art Need to Oversize Weapon Bores and Loss of Accuracy Thereof

Abstract

The present invention relates to rifled weapon barrels and sleeves (hereinafter this also applies for example to the bores of pistols and machine guns etc.) having a nitrided interior surface with a layer of thin dense chrome deposit thereon. The inventor has discovered that a thin dense layer of chrome having thickness of 0.0001 to 0.0002 inches unexpectedly falls within the tolerance of the bore of the barrel (and sleeved bore) as specified by the manufacturer, and the thin dense chromed rifle barrels, and sleeves, of the present invention unexpectedly do not need to be oversized as is the case with respect to chromed bores of the prior art (of standard thickness 0.001 to 0.005 inches). The additional benefit of the hardness of the rifle barrels and sleeves of the present invention unexpectedly do not have to be replaced as often as chromed barrels (and sleeves) of the prior art.
