This little tale will make you more angry than afraid.
This is directly from a convo with Jeff from DSA.
Apparently, DSA got verbal approval from the "Owens" staff at ATF Technology Branch, prior to beginning production of the STG 58A kit rifles.
The brake was 23mm in diameter, a closed in front, and pairs of ports at 90 degree intervals around the nose of the brake. A muzzle brake by all accounts, having none of the characteristics of a flash hider or grenade launcher.
Apparently, the new head of Technology branch likes to compare apples to oranges. They have been comparing the flash signatures of the new DSA brake with the flash signature of the Belgian multi function device (22mm, 2" long, triplets of 40degree slanted forward holes at 90 degree intervals). The MFD was given a flash reduction value of FIVE and the new DSA brake when compared to it was given a value of 2.
Apparently, it was ignored that the STG58 came with a four-tine flash hider that surpasses the vaunted "vortex" in it's flash suppression capability.
So now the ATF says that the new brake "may" reduce flash enough to be considered a "flash hider".
DSA is actively seeking independant, fair analysis of the device and it may go in DSAs favor. Perhaps not.
Rather than put DSA's customers in a bad position regarding compliance with the 94 "Ugly gun ban", DSA recalled the kit guns.
I have recommended that DSA aquire independant proof, comparing their brake with the original STG 58 flash hider and then suing the shit out of the ATF Technology Branch for "Abitrary and Conflicting" official approvals and Abuse of Authority.
Interestingly enough, ATF does not have the authority to deem any device an "approved brake" or "non-approved flash hider" except in individual cases involving prosecutions.
There has been ZERO prosecutions involving "interpretation" of brakes/hiders.
There have been ZERO convictions involving same.
DSA is doing the right thing by not putting customers in jeopardy.
I have only installed five of these brakes and on all of the rifles the flash was significant and blinding.
Want to help? Call the ATF Technology branch. Complain about arbitrary "interpretations" based on faulty methodology.
Call your Congressdork and complain that we gunowners are tired of being jerked around by faceless, unaccountable bureauRats who have the ridiculous power to graciously allow us to be "compliant" one month and "felons" the next.
Better yet, demand a repeal of the 94 gun ban and the "characteristic" sections of that. The whole mess (and indeed, much of what the 103rd Commie Congress passed and was eagerly signed by Komrade Klinton) has proven to be "unconstitutionally vague".
