I don't care what's in your wallet. I just want to know what's on your muzzle, and how well it works for you.
I have a Fabian Bros. Muzzle Stabilizer, AKA the DTA Mil-Brake, but it doesn't say that anywhere on it. It just has the Fabian Bros trademark, MUZZLE STABILIZER, CAL. 5.56. The 4th one in the picture is a "California compliant muzzle device. Not a flash-hider." that they're making now. "Due to incredible demand, the Fabian Bros. Muzzle Stabilizer is back in active production and provides significant benefits for automatic or semi-automatic weapon systems." Mine has an expansion chamber with 3 rows of 4 small holes in the rear compensator portion. In front of that is a smaller diameter hole and an A2-style flash hider section. It looks like the 2nd and 3rd one in the picture. It has a jam nut so you can clock it to any position you want. Mine is at 12 o'clock, but if I had full auto I might need to adjust that.
How well does it work? Back when my dad was still alive we were at our cabin in the middle of the Hiawatha National Forest in the U.P. There was another cabin on an adjoining property but very rarely anyone there. The owners refused to sell 70 or so years ago and it's basically just 2 cabins in the middle of nowhere. There's a point I'm getting to. When the moon isn't out it gets darker than a raven. The
inside of one. You literally can't see your hand in front of your face.
I had the Mil-Brake on a 16" barrel on my AR and walked out in the yard, loaded one round, shut off my flashlight, and fired into the ground about 5 feet in front of me. Bang, and that was it, little to no discernible muzzle flash, like a firefly so far away you barely saw a blink. I got my dad's Mini-14 with the standard 18.5 inch barrel and no flash hider, and did the same thing with another round from the same box of ammo. Bang, and the flash was so bright I was half-blinded. I turned on my flashlight and was still seeing a big blob of light everywhere I looked until my retinas recovered. I couldn't even see the cabin for a few seconds. I haven't fired enough rounds fast enough to say how well the compensator works, but the flash hider in front of the expansion chamber works great. I saw a different video of a guy testing several muzzle devices on full auto, including the DTA Mil-Brake, and will post it if I find it again. Some rounds make a flash you can easily see and some don't. Here's one on a Galil.
P.S. The muzzle stabilizer is the same diameter as an A1 or A2 flash hider so you can still use a bayonet with it. It looks like my blade sticks out an even 4" beyond it.
