Has anyone ever heard of these? They claim to be non-regulated initiators?

Do you mean like this specific e-match or e-matches in general?

I have different ones, same principle. Not sure about chemistry, but the ones I have are chlorine oxidizer based and are impact and friction sensitive, I believe they are considered pyrotechnic devices and have according regulations, if not stricter ones, because of sensitivity, ant there has been accidents because of this.

they advertise these initiators and ematches separately.

have not seen anything like that, picture in link does look like simple e-match, the plastic is protective cover for the e-match head.

I believe that only changing composition of match head will improve safety.

According to the ATF, Firewire and E-matches are completely different...E-matches are regulated and restricted in sales while Firewire isn't. I've seen both e-matches and firewire with the plastic protective cover. In fact, i have about 50 Firewire matches in my lab with those covers right now. It's politics with the ATF that makes Firewire non-regulated and other e-matches regulated.

And word on the street, is that the ATF is going to be making some policy changes on some of the regulated e-matches out there soon. One can hope, because this game has been played for years and it's ridiculous.

I use Firewires for high power rocketry deployment. The Firewire 'initiator' and the J-Tek ematch have totally different burns. The Firewire is observedly less energetic but will light a BP charge which is all that is necessary for rocketry duty.

When I held an ATFE permit the local office would request an MSDS sheet for the product to determine if the 'ematch' is regulated or not. I suppose they are looking for compounds in the Orange Book explosives lists.

And the politics is true, if you call anything an 'igniter', the ATF will claim regulation over it regardless of its compound.

MJG makes the Firewires, they are very similar in use to MJGs normal e-match, but use a mix that avoids certain compounds that the ATF has on a list for regulated e-match, thus they are non-regulated. But at some point, the ATF could change the list or rules and throw a monkey wrench in to things. They appear to work fine in place of e-match.

Keep your ears to the wall. I have peers that are headed to DC this weekend for a big meeting about this exact topic. Fingers crossed for a common sense resolution!
