Has one one used this and a Dead Air Keymount Flash Hider to mount a SiCo Hybrid?

My Hybrid is sitting in my safe waiting for a mount, but the SiCo three prong flash hider for the ASR mount is rarely in-stock anywhere. Good idea, bad idea or other thoughts? I'd like to get my can mounted so I can use it on duty.

It seems to have pretty good reviews.
