Replacement C-Shells
Replacement C-Shells fit all CS-1 and CS1-A2 Gogglehelms made — 2023 and newer. They come with left and right side internal cheek vents and Velcro hook panels installed, and a user guide. Swapping shells involves removing 8 screw fasteners from the existing GoggleHelm: 2 at the rear, 2 on both left and right sides, and 2 on top for the picatinny rail. Installing these fasteners gently, with minimal tightening force is a must, to avoid stressing the shell. Overtightening fasteners causes stress cracks in polycarbonate plastic. If threadlocker is used on the screws, it must be formulated to be safe for plastic. Loctite 245 is an excellent choice. Most common threadlockers will attack the plastic and cause stress cracks around the hole, which can cause shell failure.

NOTE: Polycarbonate (PC) is arguably the most impact resistant polymer available. This is the same material used to make ballistic safety lenses and bulletproof glass. However, PC will NOT TOLERATE constant, localized stress such as over-tightened screws. This causes stress cracks and ultimately breakage. CS1-A2 Gogglehelms are assembled by hand, with fasteners secured very gently. Always follow the instructions included with your replacement shell. Never put any material like spacers or webbing strap in between the picatinny rail and the shell.
