CTM TAC APEX Magazine Extension Base Plate for Hi-Capa

The CTM TAC APEX Magazine Extension Plate is a refined upgrade for TM Hi-Capa gas magazines that improves both functionality and handling. Compared to the original base plate, it provides approximately 4 to 5 additional BBs and an increase of around 8 to 12 g of gas capacity, allowing more shots before refilling. The 6061 aluminum construction is not only highly durable but also lighter than previous generations, keeping magazine weight to a minimum. Its ergonomic shape allows for faster and more secure reloads from various angles. The extension is fully compatible with CTM Hi-Capa magwells and includes a Tokyo Marui-spec fill valve, providing everything needed for installation without requiring additional parts.
