Nextorch's FR-1 Tactical Flashlight Ring turns any compact flashlight with a tail cap diameter of 23.2-25.5mm, like the Nextorch TA30, into a flexible, tactical tool. Screwing between the body of the torch and tailcap, it provides a ring to facilitate deployment during searching, aiming and shooting.
FR-1's rigid retention ring helps reliably index and deploy the flashlight from both pockets and pouches, while the shooter is able to continue shooting with a natural two-handed grip and retain light on target during reloading or malfunction clearance.
Being mounted between the tailcap and body of a torch, FR-1 is secure regardless of impact, moisture or temperature change, providing fast deployment and enhanced retention during many non-shooting activities, as it can be hocked to your jeans.
I consider the FR-1 a must-have flashlight accessory, optimising ergonomics for searching and shooting, but will have to run it through MONCh GearBox testing first.
