Handy for your range bag or to take to the field - Real Avid The Gun Tool Shooters Multi-Tool

This is a well made utility tool for making minor repairs to your firearm in the field. It's choice of tools, particularly allen wrenches, is limited to a few sizes and omits some of the most common ones used to remove accessories from a rail, for example.

I especially got this one to put with my shotgun range bag, since it has a choke tool as well as other more common items like a knife blade and screwdriver set.
