LARGE FLAT-HEAD SCREW DRIVER
The large flat head screw driver can be used for various tasks on your rifle.
It can be used to remove or install the pistol grip, butt stock, and swivel
sling. It can also be used as a carbon scraping tool. Use extreme care when
removing carbon from rifle components. Scraping with to much pressure
can cause damage to rifle surfaces. To use, extend the screw driver until it
locks into place, then close the tool handle completely. Use as necessary to
remove flat head screws and for scraping.
