Patrol Base GBB Winter Sidearm Pack

We all know that when things get chilly, GBB pistols suffer the most! To correct that, the GBB Winter Sidearm Pack was put together to keep your metal slide GBB doing what it does best in near-freezing temperatures thanks to the increased power of NUPROL 3.0 red gas. This pack is perfect for GBB pistols with a metal slide such as RAVEN, VORSK and WE pistols but we do not recommend NUPROL 3.0 for pistols with a polymer slide.
