Q
LetsGoBrandon, member, from MN, United States, asked on July 21, 2022

Does it have enough clearance for a low profile piston setup? I'm gonna assume so, most Daniel defense rails do. just wanna be 100%

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on August 25, 2022

Daniel Defense does not state if the Daniel Defense DD M4 Rail can be used with low profile piston systems. Daniel Defense states that it is compatible with low profile gas blocks and has an inside diameter of 1.08". So if you specific piston system has less than a 1.08" height then it might fit but I recommend contacting Daniel Defense to confirm.

Expert Answer

Answered by Hunter, Gear Expert, from OH, United States, on April 22, 2022

The Daniel Defense DD M4 Rail that is for a rifle length gas system can be used with other length gas systems as long as the rail is not longer than the barrel. You will also need a low profile gas block and Mil-Spec receiver.

Jimmy james, member, from PA, United States, asked on June 07, 2021

Will this fit on the DDM4 V7 ? I have the 10.3 inch barrel V7.

Expert Answer
A
Answered by Brandon B, Gear Expert, from IL, United States, on October 18, 2021

Yes but you will need to remove the handguard, loosen the barrel nut (working around the gas tube) and removing the barrel assembly from the upper to swap out the Bolt-Up Plate. With the bolt-up plate swapped out, reinstall the barrel assembly and continue rail install.

WhiteFang, member, from IL, United States, asked on May 21, 2021

will this work on the ddm4v7 16 in?

Expert Answer
A
Answered by Brandon B, Gear Expert, from IL, United States, on October 18, 2021

Yes, however it will depend on when it was made. Older configurations of the DDM4v7 with the Tubular style “Modular Float Rail 12.0” will need to have the barrel nut swapped out. Current DDM4v7 equipped with the MFR 15.0 will need to have the bolt-up plate replaced to install the DDM4 Rail
