The Scientists And Engineers Have Been Hard At Work In The Workshop And Laboratory Creating A Barrel That Is Out Of This World. The End Result Of This Brain Trust Is A Barrel Brand Simply Known As Mercury Precision. Mercury Precision Barrels Are Machined From F.J.

The Goal With Mercury Precision Was To Create A High End Barrel That Does Not Require A Space Travel Budget To Afford.

This Mercury Precision "Satellite" Barrel Is 16.5" Long And Is Made From 4150 CMV And Has A High Quality QPQ Black Nitride Finish. This Treatment Increases The Barrel's Hardness Significantly And Makes It Extremely Corrosion Resistant.
