Zenitco B-9 (B-9AK, B-9M) Gooseneck Rail Installation

Installation and overview of the Zenitco B-9AK Gooseneck rail platform. Specifically showing the exact measurements of different parts of the B-9 and testing its fit with three different flashlights (Streamlight TLR-3, Fenix, UTG laser + light).

Specifications & Measurements
Weight: 48 grams | 1.2 oz
Length of space taken up on gun: 5 cm | 1.97"
Length of rail space: 6.5 cm | 2.56"
The length of rail space is a bit misleading because most flashlights will hang low enough to clear the "gooseneck" and therefore won't collide with it.
