How far was it out and on which way??
I don't know what shooting experience you have but it could be the way you are holding/shooting the rifle. A springer needs to be allowed to recoil.
Most Lightnings I have heard or had experience of have a pretty harsh recoil straight out the box. As extreme as it seems a strip down, clean and relube could be worth a try.
Check the stock screws arent loose & make sure the barrel/silencer is tight, also try swapping the front/rear mounts round and see if it improves.
You might need to pack the mounts to get it on the button.
But without any
