TEC-T323-2X Isotope PRE (Picatinny Rail Edition)

IMPORTANT NOTE: This product DOES NOT include tritium vials. Please refer to our Tritium Primer to learn more about tritium and where to purchase it. The TEC-T323-2X Isotope Fob is designed around the use of two glass tritium vials (not included), which will glow continuously for many years without the need to charge it from sunlight or UV light. Designated as the PRE model (Picatinny Rail Edition), it takes our original Isotope design to the next level. With a visual appeal rooted in the military standard rail interface system, this Isotope accepts TWO standard 3mm x 23mm tritium vials for twice the brightness and twice the color! Eight large thru holes allow for maximum tritium visibility, while the virtually indestructible grade 5 titanium housing offers superior protection for the two glass vials.  Due to the simple yet secure retention method, you can change out the vials anytime you like to achieve different glow colors.
