What more can be said that has not already been said about the stellar customer support and service Kelly provides? Well, I'll add this: after receiving my GK1 I found that the shroud was loose, simple fix, but I hadn't a clue that it was the loose mod adapter. Kelly responded immediately, then checkedback later to see if the problem was resolved. Then I had a issue re-assembling the gun after installing a regulator. Kelly provided step by step instructions and sent over photos to help explain. Then, again, checked to ensure all was well. This is like the "good ol' days" of customer service you just don't get anymore, anywhere else. Kudos to Kelly.
