This K&L gigaRail opens up configuration possibilities that the FX Impact OEM rail was too short to accommodate.
Torches, lasers and MOA shifting prisms are now more compatible than ever with the Impact.

In addition to more real estate, the pic rail is lower to the barrel. This reduces cant errors.
The rail is 0moa allowing for more options.

The sides of this rail feature T-slots where you can slide in optional additional rails.
