The HABU Mod 1 from Falcon 37 integrates a cheek riser into an AR charging handle. The concept was to make the charging handle more easier to use. The additional benefit is that it offers about half an inch of riser which will help out with cheek weld. The Mod 1 is designed for 5.56 weapons and a planned Mod 2 will work with 7.62 ARs.
Above you can see the HABU extended. Just like a standard charging handle, it returns to the forward position, under spring tension from the action spring against the bolt. It stays in place thanks to a new latch which doesn’t require a release lever. If the shooter needs to take immediate action, it is similar to racking the slide of a pistol with the nonfiring hand.
The HABU is designed to fit any stock and is manufactured by Bill Rogers exclusively for Falcon 37 from 7075 T6 Aircraft Aluminum and MilSpec Hard Coat Anodized. The cheek rest portion consists of 80/18 glass polymer.
I understand it will be available this week through Bravo Company.
