Local And Compliance Notes
Loftus Firearms is the knowledgeable firearms parts source in Evansdale, Iowa, and serves customers in the nearby cities of Waterloo, Cedar Falls, Hudson, Dunkerton, and Jesup. Iowa enacted constitutional carry in 2021 under Senate File 535, allowing law-abiding residents who are legally permitted to possess a firearm to carry openly or concealed without a state-issued permit. Residents who want reciprocity recognition when traveling to other states can obtain an Iowa Permit to Carry Weapons through their county sheriff’s office.
Most gun parts are unregulated accessories that do not require a background check, but certain components are classified as firearms under federal law and require the same transfer process as a complete firearm. Serialized receivers, including AR-15 and AR-10 lower receivers, are legally defined as the firearm and require ATF Form 4473 and a NICS background check at the point of purchase. Buyers of serialized components must meet all applicable federal and Iowa state eligibility requirements. Certain parts regulated under the National Firearms Act, including auto sears and registered machine gun components, are subject to additional federal restrictions and transfer requirements.
Iowa residents should be aware that assembling certain regulated firearm configurations from parts, such as a short-barreled rifle or short-barreled shotgun, without prior ATF approval and a tax stamp is a federal felony regardless of whether each individual part is legal on its own. When in doubt about the legality of a specific parts combination or build project, consult with the staff at Loftus Firearms before proceeding. Store all firearms and components securely at home to prevent unauthorized access, and contact Loftus Firearms directly for guidance on parts compatibility, legal build requirements, or upgrade recommendations for your specific platform.
