The Maxim MD9 904S is a 9mm short barreled rifle engineered for hearing-safe performance at the range, in the field, and for home defense applications.
Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs. They now transfer on a standard Form 4473 with a background check. Anything below that mentions a Form 4, a wait or a tax stamp was written before this change. What changed
