Capitol Armory is licensed in all suppressor-friendly states. Form 4 or 4473? Read 4473 vs. Form 4 Suppressors. Your choice during checkout. See how suppressors direct to your door works or choose to send to your local dealer.
Under ATF's October 9 policy, you can buy a suppressor on a 4473 in some states. We still recommend a Form 4: it stays compliant if the policy changes, and ATF approvals come back in days.
