Their original Charging Handle design, a time proven winner time and time again. Another R/T original design using aircraft technologies for its structural hard anodized shank as well as its progressive rate spring surrounding an exquisitely machined all Stainless guide rod. A simple hitch pin is removed after installation, making spring changes a cinch, and cleaning a trouble-free affair. The modular handle design and color choices have become a popular favorite amongst 10/22 custom builders and weekend warriors alike.
