Questions & Answers
Will a 9” MFR fit on a DD mid Length with an A2 front sight base? The rail is designed with a lip at the front bottom - fear FSB interference issues. Expert Answer

The Daniel Defense MFR XS Rail Systems are designed to be used with low profile gas blocks and use a barrel nut opposed to delta ring and handguard cap. I would just recommend replacing your fixed front sight for a low profile gas block in order to fit this handguard as it was intended.

Great rail for pistol build by sgtgamez, September 28, 2017
This handguard is flawless and perfect just like one would expect from DD. Installation is easy, and it fits nicely over a low profile gas block. Everything you need to install is included. It's a bit pricey but worth it in my opinion.
