Angry Bull discusses the potential benefits of upgrading to the Hi Capa 5KU Lightweight Aluminium Frame. This frame, constructed from CNC 7075 Aluminum, features an anodized matte finish and a 2011 marking. With an approximate length of 160mm and a 20mm bottom rail, it also boasts an improved hammer housing version. This version includes a stainless steel sear, valve knocker, and pin set. Notably, this frame is suitable for the Marui Hi-capa gas blow back pistol. The question at hand is whether this upgrade is worth it.
