SLR Build With Fb3.0 Gearbox

SLR Fb3.0 gear box

Welcome to the community. Very nice piece there, I am building the exact one. How does she run?

Yeah nice one :+1: Do they fit the SLR with no hassles?

Yeah I’d love to know how it’s performing too…

They fit perfectly but the top of the gearbox will foul on the ejection port release, some light file work will clearance it. Apart from that its like they were designed to fit together.
