McGuinness Custom K31
The McGuinness Custom K31 showcases exceptional accuracy, consistently achieving sub-MOA groups with Swiss GP11 ammunition. Its custom CNC-machined stock, featuring a thumbhole and adjustable cheek piece, significantly enhances ergonomics. Modifications like the Rock Solid scope mount and St. Marie muzzle brake further improve its long-range capabilities, making it a formidable custom build from a classic surplus action.
