R-Lock/Arca Dovetail Rail: Bergara HMR



Limited qty variant explanation:

  • Anodizing Blem - minor coloring defects in the finish, typically in the R-lock holes


This forend accessory rail attaches to the forend of the Bergara HMR style stocks.   Two variants are available.  The light rail is lightened on the top side for the weight conscious hunters and competitors and matches the length of the forend.  The heavy rail does not have lightening cuts and extends forward of the forend about 1.75" for more rail space and bipod "wheelbase".

Installation requires drilling through the forend for  the rear screw locations and either tapping threads or adding the t-nuts in the forend channel.  Download a technical drawing and see the Bergara HMR Arca installation shown here.

It is currently offered for the following configurations:

R1100 B Fits  Short Action Stocks - light, standard length

R1275 B Fits Short Action Stocks - heavy, extended length
