Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on February 11, 2022

The Geissele Super Modular Handguard will only fit your rifle if you remove the delta rig, remove your fixed front sight and replace it with a low profile gas block. At that point you can use the included hardware to install the rail.
