L'Antre Du Dingo presents three new retrofit kits from TNT: the 1911 V2/Hi-Capa, P09 V2, and the GHK G17 Gen 3. The kits are machined from a single piece of CNC anodized aluminum and feature a matte finish. A key feature is the easy-to-access adjustment screw, which allows for hop-up adjustments without disassembling the slide. The kits also use a "top dead center" pressure system for consistent pressure and include a joint alignment guide and an adjustment tool. He tests each kit and finds that they simplify the hop-up adjustment process and provide better trajectories. In the end, he says that these kits are a worthwhile upgrade, as they include the block, barrel, and adjustment tool, and are compatible with most VSR10-type joints and GBB-style barrels.
