This short barrel rifle is an NFA item. We still transfer SBRs and SBSs on an approved ATF Form 4 (filed online with your fingerprints and a photo) plus the usual background check, because Alabama law ties them to federal registration. The federal tax stamp is $0. We file it with you and call when it's approved. What changed in 2026 →
