Brownells AR15 Tool kits contain the tools the gunsmith or armorer needs to perform full maintenance and repairs of these rifles in the field or shop.

Each tool is designed to do its job in the simplest, most effective manner to maintain and repair these guns correctly – and save time doing it.

Brownells AR15 Tool Kits

Standard Kit contains the tools needed to work on the AR-15 and the M16A1 through A4.

Premium Kit contains all the tools of the Standard Kit, plus an additional 11 items necessary to repair and maintain the M4 carbine as well.

Both kits come in a custom-fitted, hard-side tool box that’s made from nearly indestructible molded polymer resin and meets mil-spec MIL-C-4150 and ATA specifications. The Standard kit’s foam inserts are pre-cut with spaces for the M4 tools, so you can turn it into a Premium Kit anytime simply by adding the Upgrade Kit.
