A gun background check, using the FBI's NICS system, checks for criminal history (felonies, domestic violence), mental health adjudications, drug use, immigration status, dishonorable military discharge, and current restraining orders, flagging anyone convicted of crimes with sentences over a year, fugitives, or those deemed a danger to themselves or others to prevent them from buying a firearm.

What does a background check look for when buying a gun?

To buy a gun, you must pass a background check through the FBI's National Instant Criminal Background Check System (NICS) when purchasing from a licensed dealer (FFL), filling out ATF Form 4473, verifying you're not a prohibited person (felon, domestic abuser, etc.), with states having varying requirements, some requiring permits or covering private sales, but federal law has loopholes for private sales.

What are red flags on a background check?

Red flags on a background check are discrepancies or concerning findings like criminal records (especially violent, financial, or drug-related), significant inconsistencies in employment/education history, poor credit history (for finance roles), negative references, failed drug tests, or unprofessional social media activity, all raising concerns about a candidate's integrity, judgment, or suitability for a role.
 

What is the background check law in Alabama?

Alabama's background check laws generally permit employers to run criminal history checks, following federal FCRA rules for consent, but lack a statewide "Ban the Box" law, though specific fields like childcare and law enforcement require detailed fingerprint-based checks via the Alabama Background Check (ABC) System. The Redeemer Act allows record expungement, impacting their use in hiring, and employers must follow FCRA steps like providing notice and consent.

What causes a red flag on a background check for a gun?

A "red flag" on a gun background check (NICS) often means a prohibiting record was found, like a felony conviction, domestic violence misdemeanor, fugitive status, unlawful controlled substance use (including marijuana), mental health commitment, dishonorable military discharge, or unlawful immigration status, but sometimes it's just a delay due to matching records (similar names/info) needing more review, not necessarily a denial. State "red flag laws" (ERPOs) are separate, allowing temporary gun removal for high-risk individuals, but the primary federal system flags are criminal/mental health issues. 

Why was I denied a gun purchase?

You were likely denied a gun purchase because your background check (NICS) flagged you as a prohibited person due to factors like felony convictions, domestic violence issues, restraining orders, unlawful drug use, certain mental health adjudications, or immigration status, though denials can also stem from mistaken identity or incorrect records, which you can challenge. To find out the specific reason, you must contact the FBI's NICS division, as the dealer won't know.

How far back does a background check go for a firearm?

A gun background check, run through the FBI's NICS system, generally looks back about five years for recent drug use or addiction, but for serious crimes like felonies, the prohibition is often permanent, while other disqualifiers (like domestic violence restraining orders) can be temporary. The check pulls from various databases (including FBI's IAFIS), so while recent activity is key, a criminal history, even older, can still trigger a denial if it makes you federally prohibited.
 

What disqualifies you from a NICS check?
