I really like them - Gun Guardian Multi-Functioning AR-15/M4/M16 AR Grip

The grips seemed a bit questionable when first seeing them but after the install and how simple everything is, I love them. When extended the grips seem no different but then the ability to collapse them makes storage and transport a whole lot easier. I am a bit compromise for space so my safe is not the biggest, Between optics and pistols on the inner door its takes a bit of maneuvering to close and lock the door. With the grips collapsed my issues are solved. Thanks for creating an excellent product and wouldn't mind seeing an AR-10 version
