Rise Armament Charging Handle Features The RISE Charging Handle is precision CNC-machined from 7075-T6 aluminum; this makes it both durable and lightweight. It fits all mil-spec AR-15 upper receivers. Important factors of a good charging handle are ease of use and speed. With that in mind the RA-212 features an extended latch that allows for both easier and faster charging. However the main focus here is durability. Why is that so important? Think about how much you use your rifle. Then think about how much you pull on your charging handle. You want a handle that lasts over time. The RA-212 Charging Handle is as durable as it gets. Remember we use 7075-T6 aluminum. Beyond that the RA-212 also has a hardcoat anodized flat black finish. A couple of key benefits of the finish are durability and corrosion resistance. The finish is also harder than tool steel so it provides serious strength. Add that to the aluminum's light weight and you have one of the toughest charging handles you ll find.
