FX Panthera Upgrades from Saber Tactical: Drop-Down Adapter, Arca Rails and Hunter Top Rail
The Panthera has a loyal following, and we have built a family of parts around it. Most owners start with air capacity or a better bottom rail, and many add weight later for matches. This post organizes our Panthera parts by what they do.

Front Bottle Adapters
Drop-Down Front Bottle Adapter ST0060
The ST0060 attaches a bottle to the front of the Panthera while you continue to use the stock Panthera rail or our Panthera rail. It is 304 stainless steel with electroplating and weighs 7.6 ounces.
Front Bottle Adapter ST0056
The ST0056 lets you attach a second bottle to the front of the rifle so both bottles work together for extended sessions. It is stainless steel.
Bottom Arca Rails
Both rails are 6061-T6 aluminum in black anodize with a lasered logo, M-LOK slots underneath, a 1/4-20 hole for camera tripod adapters and a threaded nylon tipped grub screw. The Standard ST0076 is sized for a 580cc FX bottle. The Hunter / Dynamic Compact ST0073 extends to the end of a 300cc FX bottle.

Panthera Hunter Top Rail ST0072
The ST0072 has a removable cutout section that accommodates a 300cc front bottle without moving it. If you move the bottle to the rear, replace the cutout for more Arca rail on the bottom. There are M-LOK slots on the rail and bridge, and it weighs 1.2 lbs in 6061 aluminum.
