The MASK Piston Head
ARS (Airsoft Research Syndicate) has released the MASK pistonhead, otherwise known as the Mechbox Anti-Shock Kit. It is made of Polyoxymethylene (POM), in the USA also commonly known under DuPont's brand name Delrin. Its an engineering plastic often marketed and used as a metal substitute. Delrin is a lightweight, low-friction, and wear-resistant thermoplastic with good physical and processing properties and capable of operating at high temperatures (http://en.wikipedia.org/wiki/Delrin).
The MASK piston head's design was derived from LAYLAX's MP7 pistonhead. It is devised to work with the ARS sorbo pads to maximize shock absorption and achieve the ultimate in gearbox protection. A Sorbothane is embedded onto a 2.95mm deep crater and rises only at 0.5mm, enough to act as the first surface to impact the cylinder head sorbothane damper. In theory, the surface would work as a "sponge" that will absorb the shock and distribute the impact into its core without compromising the angle of engagement between the sector gear and the piston body.
The MASK also uses a white Silicone O-ring as a standard and will come in two different sets - 1. Piston head replacement, 2. Piston head with bearing and lock. The MASK is compatible with versions 2, 3, 6, and 7 mechbox.
マスクピストンヘッドのデザインはLAYLAX's MP7のピストンヘッドから得ています。最大限の衝撃を吸収し、メカボックス保護において究極のものになしおえたARSのソルボパッドと作用するために考案されました。ソルボセインは2.95mm深くへこんでいて、0.5mmだけ出っ張っており、ソルボセインに衝撃を与える最初の表面として働きかけるのに十分です。理論的には、表面は衝撃を吸収し、セクタギアやピストン本体間のかみ合いの角度を危うくすることなく中心に散布するスポンジのように働きかけます。
マスク(MASK)も標準としてホワイトシリコンオーリングを使用し、異なる二つのセットになります。1つ目がピストンヘッドの替え。 2つ目がベアリングとロックです。マスクはバージョン2,3,6,7共用できます。
