Jaeger Precision has upgraded the Tokyo Marui LCP 2 inner barrel with a PDI 6.01 inner barrel. The 6.01mm diameter offers a tight fit, resulting in minimal air loss and excellent momentum for short-range shooting. However, this precision comes at the cost of a less stable flight path compared to wider barrels. It's crucial to use high-quality BBs and maintain the barrel regularly to prevent scratches or jams caused by wax or dust. This high-precision stainless steel barrel is crafted through cold forging for optimal performance.
