Our take: The SRC R36 gearbox is a drop-in solution for those who are looking for replacement R36 gearbox that is affordable and reliable. SRC is know for their quality version 3 products, and this is no exception. Being as durable and reliable as it is, the R36 full metal gearbox is the go to solution for replacement R36 gearboxes.
This R36 gearbox comes with reinforced stock internals that outperform most stock rifles on the market. Including more durable bushings, an M110 spring, and a reinforced set of metal gears, this is the most affordable replacement R36 gearbox that will still be able to withstand day to day use.
