FX Impact accessories (including M3 and M4)

The FX Impact family drives most of our FX accessory sales. Typical Impact upgrades start with a TRS top rail, an ARCA bottom rail, an RFB or adjustable buttstock, then cheek pieces and bottle adapters.

FX King, Dynamic and Panthera

For FX King, Dynamic and Panthera builds, start with the King chassis (a top chassis seller), the ST0093 conversion kit for Dynamic-block rifles, and matching extension rails.

FX DRS

The FX DRS Chassis is one of our highest-grossing FX products and moves a DRS Classic, Walnut or Synthetic action into a rigid aluminum chassis with Arca rail, M-LOK and an adjustable cheek rest.

FX Maverick

Maverick shooters usually start with a Maverick TRS, cheek riser, bag rider or double tank adapter. See FX Maverick accessories.

FAQ

Do you sell FX Impact accessories for both M3 and M4?

Yes. Some parts are generation-specific (M4 TRS and M4 cheek pieces), and many Impact rails, stocks and adapters fit across Impact generations. Always read the Fits section on the product page.

Is there an FX Impact chassis from Saber Tactical?

We do not currently sell a drop-in chassis that replaces the entire Impact stock the way the King or DRS chassis does. On the Impact, the TRS top rail, bottom rails, RFB buttstock and adjustable buttstock are the main structural upgrades.

Can a Dynamic or Panthera use the King chassis?

Yes, with the ST0093 conversion kit paired to the King chassis. Confirm fitment details on those product pages.

Where can I read field testing notes?

Start with our Field Notes on FX Impact gear, the RFB buttstock, the FX King chassis and DRS MKII testing.

Compatibility is listed per product from real fitment. We do not invent model support. If a product page says it does not fit a generation, trust that note.
