Hyperdouraku reviews the first P90 Gas Blowback, the WE Airsoft TA-2015. This P90 has a metal upper receiver with a nylon fibre lower frame. It has 20mm rail for a top rail so you can install weapons accessories on it. This is fully ambidextrous, with the Charging Handle and Magazine release can be handled with either hand. Blowback is said to be hard and it also has a locking bolt mechanism.
