TEAM ASSOCIATED TC7.1 FT BRASS ARM MOUNTS (INNER)
These replace the stock machined aluminum mounts (#AS31619) with a machined brass version for increased mass. They are heavier than the aluminum version by 2.5 grams each.
A combination of these mounts, or completely replacing the stock mounts, helps with tuning the overall center of mass. Sold in pairs. The additional weight of the mounts is laser-etched.
