Line SI Promaster. This was my first Promaster, which cost about $400 in 1990 or '91. Since then it has been through thousands of rounds of paint and many modifications, the latest of which includes a vertical ASA from ICD (Indian Creek Designs), a LAPCO grip, a WGP In-line regulator, a valve extension chamber made from a WGP Sledgehammer low pressure regulator body, a Spyder bolt, valve and valve pin, an old L-stock with a WWP bottomline ASA, a flashlight, night vision scope, and a barrel with a custom built-in silencer (inset).
