George, you should get the kit today or tomorrow. If you use the red dot then it will need a battery, I don’t recall the size, 2016 maybe. You will need to install the spring and spread and guide. Just install it into the Mellon Air power adjuster, screw it in until it seats. You should have a little bit of space for the hammer to slide fire and aft a bit. If not then remove the spring and guide and shorten it a little.The extra long power adjuster you’ll u can sell if you want, I think it was about $30 or so.Hunter
The thread about the development of the SSG (stopping spring guide) can be found here:https://www.gatewaytoairguns.org/GTA/index.php?topic=102095.msg960287#msg960287It is a very long thread but all information is contained within this thread.Hunter
