The Flexi Joint + Gun Clamp adapts to the Quad Rest 3. It replaces the front V support. 

INCLUDES STRUT SUPPORT SYSTEM

It is designed to give the shooter better security for the rifle, a better hold for accuracy and an overall upgraded experience while using the Quad Rest 3. It is also the best option for large magazine and pistol grip style firearms because it has ample space and clearance. 

A strut support system can also be fixed on to the Flexi Joint + Gun Clamp as shown in the images. The strut support system was designed to keep the flexi joint stable and still unless the shooter voluntarily moves the joint to position for a shot. It also supports better zero hold on a target.
