How Iowa Law Affects Your AR-15 Build

No Magazine Capacity Limit

Standard 30-round AR-15 magazines (and larger drums) are legal for sale and use in Iowa.

Iowa restricts some or all NFA items (Machine guns / DD banned). Suppressors, SBRs, or other regulated items may not be available even with a federal tax stamp. Verify before buying a 14.5" barrel or pinned muzzle device intended for SBR conversion.
