Well I got my Kraford & Lypt Arca Adapter from Utah airgun couldn't wait to get it on my gun. It slid right into the T-slot on the Extended Trigger Rail also made by them. I tightened two of the three set screws and the install was done. I set it back as far as I could to get the balance a bit closer to center which on my Impact is right in front of the trigger. Nicely designed, machined and finished piece it is. Utah Airguns mistakenly sent me the beautiful $160 trigger rail but I sent it back, even though I would have loved to keep it, cuz it is not what I paid for. 
Once installed I slid the gun onto my gimbal and now I am ready for?
