Well, i finally got my front sight off! (It took forever!) I had to take apart my gun to get off the front sight.. It was soooo worth it though! I also went out and bought a Gemtech Blackside Silencer, plus a Tenenergy 9.6 1600 Mah battery... Then i have my vertical grip also.. Go to my youtube site and i will have reviews on all my upgrades and even shooting test..
