3 prongs? wat...
Sordins usually come with a
Lemo 6 pin connector, modified ones will likely have a
TP-120 connector.
If you have the Lemo 6 pin, you have 2 options:
1-Get it modified to a TP-120. (SRS Tactical or somebody that knows how - the mic will also need to be changed if this is a un-modified headset)
2-Get a pigtail or a coupler to adapt it to a TP-120. (found on EBAY - mic still needs to be changed)
Once it has a TP-120 connector, you can use a fake or real PTT.
Keep in mind that the fake PTTs MAY not be wired up the same as the headset, and will need to be re-wired.
Also note, that the cheapo fake PTTs are one of the biggest weak points in repro comm setups. If you are investing in real sordins, invest in a real PTT like the Nexus U94, you wont regret it. (buy once cry once) Again, SRS tactical can help you with this.
As for the arc rails.
Again, 2 options, that I know of anyways.
1-Find some custom modified peltor adapters, there is a guy here on ASC that I got mine from. (Rookie Ab)
2-Modify your headset to work with the stock peltor adapters using a
SARA kit.
