Designed by retired US army ranger Justin Gingrich, the WeaPen tool BitMag pairs with the advanced tactical WeaPen tool AR. Together, they complete your powerful, but pocket-sized AR field-strip kit. The BitMag's six steel hex bits are secured with a heavy-duty spring steel pocket clip and internal TPR spring, keeping your bits in place and quiet. The six-bit setup gives you everything you need to field strip your weapon - all contained in durable textured, lightweight polymer case that's easy to carry next to the WeaPen tool AR. When you're in the field, every inch of storage and ounce of weight make a difference. 5.11's WeaPen Tools are the small but mighty accessories you won't want to be without. Material: Steel.
