" Great gearbox. Was everything I thought it would be.
" These gearboxes are absolutely beautiful and machined very well. FLT bushings fit flush on both sides although they were extremely hard to fit in the shell, I removed some material from the inside of the bushing holes to accommodate. Everything else fit absolutely fine, almost every part in my gearbox is SHS except the cylinder is LCT and the cylinder head is King Arms. This gearbox is extremely light, very strong and easy to use, with extra features making it easier to tech on. Installed a JeffTron Leviathan as a drop-in fit, aftermarket MOSFETs require no modifications to install. Overall great product! I’ll have a video review up on my YouTube channel Octane Airsoft shortly!
" These Gearboxes from Retro Arms have been a game changer in the teching world. I absolutely love how well these are machined and fit. The fit and finish alone is beautiful and is almost worthy enough just hang on a wall. The level of reinforcement that is in these gearboxes is amazing! I have been running these gearboxes in many different builds and I must say, this is top notch quality
