muzzle shroud on the SFAR

[OldGraybeard]

has anyone put a muzzle shroud on the SFAR over the "Boomer" brake?

Not sure what you're referring to but there are devices called 'blast cans' that replace a muzzle brake. One device that actually helps is made by Witte Machine (Sound Mitigation Equipment).

The Indian Creek Design BFD (Blast Forwarding Device) https://www.indiancreekdesigninc.com/bfd-info-and-faq . Installs over the muzzle brake. From the video looks like it would alot of difference

I watched the video and just gotta say the Witt is better IMHO. Similar concept but slightly different approach. The WITT is a bit expensive so I didn't replace the one that melted when my UTV burned in the wildfire. Currently, I use a 'knock-off' of the WITT device on the AR I carry on my UTV and it does help reduce the muzzle signature at the shooter's ear.
ebay is full of similar type muzzle devices-many of which are somewhat flimsy.

Does it loose some of the brake aspect of the device when its projecting the sound (and as a result the gas) forward?

No doubt the 'blast forwarder' has some effect on the 'muzzle brake' due to the restriction/re-direction of exhausting gases. The (recoil) brake acts by allowing the muzzle gases to exit sidewise rather than forward while 'pushing' forward against the ports in the re-direction process. Anything that restricts this action will reduce the 'braking' action of the muzzle device. IMHO, muzzle brakes are most effective with cartridges that have a large amount of muzzle blast--higher powder capacity, higher pressure, or shorter bore length.
I have a matched pair of 6.5 Creedmoor rifles- one with a suppressor and one with a 'blast forwarder'. There 'seems' to be more recoil with the blast forwarder but w/o doing a test by having someone else shoot the rifles blindfolded, I can't positively confirm this.
