  • Aves FMDA DD26.2 Rail Kit

    The FMDA DD26.2 brings the ease of assembly and durability of the DD17.2 and DD19.2 to an even more compact frame.

    The front rails for this kit are a completely new design to the DD26.2. Designed by Deterrence Dispensed and initially prototyped by Aves Rails, we are proud to have participated in their development. The rear rails are an all new design specific to the various DDxx.2 frames. Made from high quality stainless steel. Precision formed to fit your frame perfectly every time. The rear rails are supported by the frame as well as the trigger components. Because of this we have developed a holder to be used in transit to protect your rear rails until they are ready to be installed. This ensures they are the proper size upon delivery, providing you with the easiest assembly of any printed frame.
    To complete a DD26.2 frame you will need these rails, a lower parts kit for a gen 3 G26 and a compatible slide for a gen 3 G26.
