Another "interesting" variation on the theme was one that had a "clone" of the AK-74 muzzle device attached to a 7 1/2" barrel and actually worked, but was horrendously loud, especially out to the sides, and in "low light' lit the place up like a fireworks show.
The "74" gizmo has an expansion chamber at the rear. the gas exits by either the small-ish bore hole forward or a couple of very small holes on top; "compensator"-style. The front section is a simple baffle "plate in front of two BIG rectangular ports, one on each side.
The small holes in the main chamber are supposed to help keep the muzzle down and the forward baffle plate acts as a simple "brake". The "downside" is the noise, especially to the sides.
A LONG time ago, there was a TV series called, "Comrades", with each episode covering a different aspect of then-current "soviet" life. One episode was about a young man going off to do his military service.
There they all were, in a fairly tightly-packed firing mound, and all armed with AK-74s. Conspicuously absent was any sign od hearing protection for the trainees or the instructors.

I had a 14.5 with a fancy muzzle break made by a local business here...it increased the noise and blast to an unacceptable level under the guise of reducing felt recoil...
The noise when in the shooting sheds was unbelievable, once removed the carbine was fine. After all, recoil? This is 5.56, let's just take the "Recoil", shall we? It wears a standard A2 FH now.

Pix of "after-market" muzzle devices from the 1980's.
The bottom one is the "aftermarket "74' brake made to fit the 1/2" x 28 thread on AR-15 variants.
The top one is the "Fabian Brothers Muzzle Stabilizer" for 7.62 NATO goodies and is threaded 9/16" x 24.

The right one in the second photo I like OK. The other promises to be noisy...

The "Fabian Muzzle-Mizer" / "DTA Mil-Brake" is basically designed to reduce muzzle RISE, via the ports and chamber in the rear half of the device, and to reduce flash via the conventional slots in the front section. Having seen (and felt) them in action on FALs and M-1As, I reckon they work. The interesting one, as I recall, was the .308 / 7.62 brake fitted to a "short" M-1A. The effect of the "downwards" force from the "compensator" ports was sufficient to make it feel like the rifle was rotating and the butt was "smacking the firer in the chops", at every shot. Not really "unpleasant" just "different".
The wildest one of these gizmos has to be the "whistle" device on the front of the 5,45 x 39 Russian AN-94. This gadget is supposed to be "tuned" to both "optimise" gas function and reduce muzzle blast by some sort of "phase cancellation" effect.
I have NEVER handled or fired one, so I leave further analysis to those who have.
