Just wanted to chime in here with some praise for John, the tech at Fire Support.
He’s just finished working on a pair of Marui MWS GBBRs: a custom-built L119A2 and some internal work on a CQB-R M4. Great service... John is very knowledgeable and meticulous in his work, phoning to check on each stage of the job, offering advice throughout and machining some of the parts where necessary. Very good rates for his time, too.
Can’t speak of his AEG work but I hear it’s also first class. I’ll be using him again for sure.
