S&T released news of a Type 64 Battle rifle on their facebook on August 19th 2014.

Echigoya predicts a release sometime around November. The rifle will be an AEG and not a GBBR like some predicted Maybe it's a Clone of the limited run Top Type 64. The rifle will weigh in around 3.26 kg just being 1.14 kg shy of the weight of the real rifle.
Aluminum alloy is used for construction of the receiver, outer barrel, front and rear sight. Steel will be used for the bipod and heat-shield. Real wood for the Hand guards and butt stock. The rifle will uses a 380 round hicap, no news on a mid cap. S&T does plan on releasing a scope mount for the type 64 and a unknown capacity spare magazine.
The Gearbox is a proprietary 8mm gearbox, no news if the internals are standard. Most likely it would be to ease manufacturering. The Shell and maybe the hopup and nozzle will be proprietary. So far only Mini battery is listed as compatible.
The price is predicted to be 52,650 yen ($530.258 CAD) it is probably unlikely to be released in North America. Looks like there will be a market for the Alice Type 64 magazine pouches.
