Luke has been involved in Airsoft for over 25 years, and is often considered one of the best Techs in the UK. Getting a RIF worked on by him generally means you are going to receive a RIF back that performs as well as anything on the field – budget dependant of course.
RIFs upgraded by Luke have been known to sell for much higher prices than they would otherwise. He can also do custom paint jobs too. He also sells a few parts on his website, such as fat-boi piston heads for AOE correction, nozzles, motor towers and gearbox clips (amongst other things).
Given all that, you can generally expect a 6-12 week turnaround, but it’s worth it. Dead Man Walking would say that you will not find a better tech anywhere.
He also has a Negative Airsoft You tube channel, and a Patreon account.
