Sorry if this issue has been hammered on here but I couldnt find anything recent on it...I bought a UTG BiPod for my sport 2 but it only went to 7.9 inches which was not high enough to securely balance the gun for it to stand up on its own when i had a 30 round magazine in it...so i am going to get a bit taller of one...is an 8-12 inch a good height to go with or am I overlooking something. Also, on the BiPod I am returning to the seller I can't figure out how to attach the part of the BiPod that allows the gun to rotate around freely (if that makes sense). I would like to have this feature if it will work with the gun...?
