Buying Guide: What to Look For When Purchasing a Multi-Tool

Functionality and Weight

When selecting a multi-tool, first consider how many tools you prefer to have on the multi-tool itself to determine which one is the best fit for you overall. 

While complex multi-tools with numerous attachments and tools can serve a wide variety of purposes, generally, the more tools included inside the multi-tool, the heftier and heavier it will be. On the other hand, purchasing a multi-tool with various different capabilities can easily take the place of other tools, thereby making your toolbox much lighter.

Because AR 15 multi-tools are much more specialized than a general multi-tool, you also need to consider the specific tools you need for your specific purposes and gear. 

Most commonly, AR 15 multi-tools should include wrenches for tightening nuts on your rifle. The wrench should be sturdy and not slip off of the nut when tightened. Also, look for a multi-tool with an included punch tool, which is used in gun maintenance when precisely driving in pins. The punch and pin puller are also useful for simplifying the task of rifle disassembly. 

You should also look for a carbon scraper, as this is essential to properly maintaining a firearm. As you use the firearm, carbon and debris build up around various gun parts, such as the ejection port, barrel, firing pin, bolt head, carrier, and other vital areas. A carbon scraper and brushes can help to clean this off so that your firearm stays in good shape.

Also, look for a multi-tool with a front sight adjuster built-in. This will ensure that you can use the sight accurately and quickly for efficient aiming on the fly.

Many multi-tools will also be equipped with other useful tools (both for rifle maintenance and day-to-day life), such as a small hammer, a knife (serrated and straight edge), various sizes of Allen wrenches and flat head screwdrivers, a can or bottle opener, a lanyard loop, or even a small ruler. 

Look for these features if you want the ultimate versatility out of your AR 15 multi-tool.

The best choices for those on a tighter budget may be the Real Avid Gun Tool Pro 30-in-1 Gun Multi-Tool for Rifles and Shotguns at $38.99, the Real Avid Carbon Boss Multi-Tool Carbon Scraper at $29.99, or the Leatherman Rail Pocket Tool priced at only $19.95.
