A very accurate and beautiful replica of the model 15.
아주 좋게 탄이 나갑니다
刻印を入れるとやはり物足りなかったスライドが一気に格好良くなりますね。手に取って眺めたときにニンマリします。オススメです。
This is a CNC machined reinforced piston for the Tokyo Marui AA-12.
The second rack gear is fully cut from the beginning, and the third is half cut.
It has rebound countermeasures in high cycles and AOE adjustment allowance.
The body is made of carbon fiber reinforced nylon.
The rack gear is made of spring steel (56SiCr7) and is fully machined and salt hardened.
The piston inner diameter is Φ15.5mm, and the stock weight is 22.2g (piston body + screw-fixing plastic parts).
However, it is quite heavy at 32.79g.
When installing the piston head, do not use the original tapping screws.
Use the included flat head screws.
