Internals for the TM? No, TM is pretty much perfect for internals, they dont shoot as fast as other guns like G&G. But i've heard people using tms and having them last for years. The only complains I had about my TM m16 (Which uses the same receiver type) are how fragile the tabs are (Tabs are what keep the two halves together)
Unless you can get a metal body ASAP, i would go for the G&G
