This guide details a DIY modification to create a custom, extended paddle for Streamlight weapon lights when used with the Tyrant CNC T.W.S. 365 chassis. The original light paddles are often difficult to access due to the chassis's magwell. The process involves fabricating a solid aluminum paddle using basic tools like a bandsaw and Dremel, then fitting it to actuate the light's internal switches with a simple hand movement.

Quick Summary

The factory Streamlight paddles can be difficult to use on the Tyrant CNC T.W.S. 365 chassis due to magwell obstruction. This DIY modification involves creating a custom aluminum paddle using a bandsaw and Dremel, which then pivots to easily activate the light's switches with a simple hand movement.

Frequently Asked Questions

Why are factory Streamlight paddles difficult to use on the Tyrant CNC T.W.S. 365 chassis?

The factory paddles are often obstructed by the chassis's magwell, making them hard to reach and actuate. They are typically designed for standard trigger guards, not specialized chassis systems.

What tools are needed to make a custom Streamlight paddle?

You'll need basic metalworking tools including a bandsaw with a metal blade, a drill press with an XY vice, a Dremel or roto tool with a cutoff wheel, layout fluid, files, and drill bits.

How is the custom paddle attached to the Streamlight?

The custom paddle is designed to pivot on a pin. This pin, often made from a cut-off drill bit, engages the light's internal rubber switches, allowing the paddle to actuate them.

What is the primary benefit of this modification?

The main benefit is significantly improved ergonomics and ease of use for the weapon light. The extended paddle allows for quick and simple activation with a bump from your support hand.
