The End of Solvent Trap Adapters?

We’re often asked about using a solvent trap adapter as a substitute for buying a suppressor from a dealer.

The person asking the question is often interested in avoiding the wait time on a Form 1 or Form 4 application and in saving the $200 tax involved with those applications. We advise folks that they should not even consider it without an approved Form 1 in hand, but would be better off looking at a good commercial silencer in the first place.

Those recommendations have been confirmed by the fact that the ATF took action on January 25th against SD Tactical out of Prescott, Arizona for marketing solvent trap adapter kits that buyers could convert into a suppressor buy drilling out the “freeze plugs” and the end cap. The ATF’s concern may have been that too many purchasers of these kits were not going through the formal Form 1 application process and were making contraband suppressors.

The problem may also have been compounded by the fact that SD Tactical is a Type 07/02 manufacturer and makes and sells commercial suppressors through the regular Form 4 process that use the same outer tube and internal parts that they were also marketing as “solvent traps” in an undrilled state. No other suppressor manufacturer is believed to sell their outer tube separately or baffles without a center hole drilled through it. It may also not have helped that they allegedly had made instructional videos of the company owner explaining exactly how to convert your solvent trap into a silencer, so it would appear very clear what the intended purpose of a “solvent trap” really was.

The ATF is reported to have told SD Tactical that they have two choices: stop marketing solvent trap adapters; or, face five years in prison. All in all, the incident makes it very clear that the ATF does not look kindly on these devices and the scary thing is that they now have the shipping records and order records of every person who has purchased such a device or kit from SD Tactical and could be looking into tracking those items down.

Clearly, this makes using such kits even more questionable and we would strongly recommend that you stay away from them. It’s not worth the risk of losing your firearm rights for the rest of your life or the large legal defense bill that could result. We would also advise those who have purchased such a kit to refrain posting anything incriminating on social media and to contact your attorney as to what you should do.
