Can the flash hider be removed for a suppressor? Expert Answer

The Radical Firearms Complete Upper Assembly 16 inch 300 AAC HBAR Contour has a muzzle that is threaded for 5/8x24. So a suppressor can be attached to the barrel using those threads or a compatible adapter.

More of a question than a review. by Homer Carter, Verified Owner, March 24, 2021

Can someone give me a suggestions on what type of “Hand-guard” can I attach to this HBAR Contour? I need something to support this unit and to help dissipate the heat. Also, I would like to know what can of furniture was used to outfit your unit.
