I can’t put enough emphasis on using gunsmith screwdrivers instead of household screwdrivers on firearms. I’ve ruined many screws with ordinary screwdrivers but no more.
Gunsmith screwdrivers are made different and fit firearm screws perfectly so you don’t strip out the slot/head and they are not expensive so there is no reason not to have a good set.
Here is an example of an inexpensive set of gunsmith screwdrivers from Wheeler.
This is a huge gunsmith screwdriver set with 89 pieces in an organized case…and all for about $66. This screwdriver set even comes with some specialty tips.
These come in handy if you maintain a lot of different firearms. If you’re interested, here is a link to get this gunsmith screwdriver set…Wheeler 89 Piece Gunsmith Screwdriver Set at Amazon.com
