Howdy all, does anyone have a DDM4 on a midlength with FSB? Or know if it is compatible with that setup?
I contacted DD and was told it would not fit, however the listed length is .005” less than the BCM QRF 9, which definitely does fit (9.235” vs 9.24”).
The graphic in the “What Rail Length Do I Need” sticky shows the length between the upper’s face to the FSB to be 9.34”... does the barrel nut & bolt up system push this out too far?
Thanks for any insight.

DDM4V3 and DD Omega 7"
My factory DDM4V3 with 9" DDM4 rail (bottom) with DD FSB.
Pistol is a DD Omega MLOK 7" on factory BCM 12.5 upper. Hope this helps.
