Works and fits well - HERA Arms 110801 HFG Pistol Grip AR-15 Polymer Black

Fit was fine on my billet lower. Size and angle are very similar to an MOE grip but it's cheaper and a bit lighter. The texture is the only thing I'm not real thrilled about. I wish it were a bit more aggressive, but it's not bad. For the price I doubt there is anything else significantly better.
