This FN SCAR stock block is used to prevent the folding of the stock on the FN SCAR rifle. This is necessary in cases where the overall length of the rifle would otherwise be less than the California minimum of 30" when folded. The block is installed in place of the standard spring behind the stock release button and prevents the button from being depressed.
To Install:
- Use a punch to drift out the stock hinge pin and remove the folding stock assembly.
- Remove the stock release button and spring by pressing on the retaining tab with a punch or other small tool.
- Put the stock block in place of the spring and reinstall the release button
- Slide the stock assembly back into place
- Use a punch to reinstall the stock hinge pin
