I'm setting up a BT-99 Micro for my 14 year old daughter. She has been shooting a Winchester SX3 but looking to start shooting more so we thought it was time for the BT that her brother's started with. She's fairly petite so I was thinking about a recoil reduction device. I have someone that can install it properly. So what's the opinions between the RAD and the Gracoil? Any input appreciated.
