If you have the Saber Tactical Chassis for your FX King/Dynamic/Panthera and also have a 700cc bottle, this rail will extend to almost the full length. This gives you more Arca rail on the bottom as well as more MLok slots on the sides. Available in bronze and grey.
Check Bottle Clearance while Installing: Saber Tactical has received some reports from customers in the EU of bottles rubbing against the back of the front rail. They have not been able to replicate this with any of the rifles in the shop, but if this happens to you stop the installation and send them your rail. They will mill out a section so that your bottle is not damaged. Saber Tactical theorizes that this is due to variations or design differences in the neck length and/or thickness of the carbon fiber bottles. If your Chassis has bare aluminum in this area it has already been modified to accommodate variations in carbon fiber bottles.
