Correction history
- Evidence passEditorial confidence: Low → High. Re-rated after supporting references were added or re-checked.
- Evidence passYears: 1961–1974 → 1962–1965. American Rifleman: New Frontier shipments began in 1962 and the 4¾" barrel ATF lists was discontinued in 1965; Guns Magazine: four-digit NF serials (3000NF–73XXNF) are the 2nd Generation run, so S/N 4411NF is a 2nd Generation gun
