I am interested in setting up a gun trust so I can legally purchase and own a suppressor/silencer.

My concern is that Obama has issued or will issue an executive order banning gun trusts. If such an executive order will exist, will it apply to suppressors, too?

No executive order has been issued that "bans" gun trusts; nor do I know of any proposed order that will do so. The proposed executive orders will merely impose more restrictions on gun trusts (e.g., fingerprinting requirements). Please see our article, "Obama's New Restrictions on Gun Trusts." 

With regard to your question about suppressors, I assume you are asking whether the executive order will prohibit individuals from owning suppressors through gun trusts. If so, then I know of no proposed executive order that will ban suppressors. A suppressor acquired through a gun trust will be treated the same as any other NFA weapon (e.g., machine-gun, short barreled rifle).

We are suggesting to all of our potential clients who are interested in owning an NFA weapon or suppressor through a gun trust to get one as soon as possible—before the new laws go into effect. Please let us know if you have any additional questions.
