Very cool idea. - FAB Defense AR-15 Quick Deployment Bipod with an Integrated AGR-43 Pistol Grip

Other than being bulky, I love this grip. When I first installed it there was a little play to the magwell section but there was a place for an extra roll-pin that they didn't include. It wasn't in the instructions so it isn't like they forgot the part. I have several roll pin kits so I found one that fit, ground it to the right length and after installing that the play is gone. This grip is in the way when I try to use my shell catcher (the clip on Brass Goat version) and it does take more space in the safe... but every time I think I'll swap it for another grip, I just can't. It's been on that build for almost 4 years now. I dig it that much. The rifle lives on an ARMA-15 wall mount lock now so the space issue isn't an issue any more. Very comfortable rubber coating and beaver-tail. Moves the weight of a bipod back for better balance while shooting off-hand IMO. It gets compliments too, not that I'm a fan of conversations at the range.
