I have been starting to consider getting one for my AR, but have a lot of questions.
My #1 is does this put me on an ATF list if they ever do start getting real gun control traction?
They already know you have a gun.
Also, what does the process entail as far as time frame and cost?
Current lead times are over 9 months for approvals, don't fart around any longer if you want one by fall. Costs are $200 for the stamp, plus cost of the suppressor, tax, & possible dealer charge.
And finally I read something about putting the suppressor in a trust so others listed in the trust can shoot it?
Anyone can shoot your suppressor in your presence, when filed as an individual.
Anyone listed on the trust can shoot it, as they are the "owners".
Neither can loan out a suppressor.
