M14 / M1A Magazines
Springfield Armory • Taiwan T57 • 7.62 NATO / .308 • 5-20 Round
American-milled steel magazines for the M14 service rifle and the civilian Springfield Armory M1A — the rifle platform that replaced the M1 Garand in US service in 1959 and remains one of the most accurate semi-automatic .308 / 7.62 NATO battle rifles ever fielded. Taiwan T57 20-round service magazines from the Republic of China Army surplus program; Springfield Armory M1A 5-round and 10-round magazines produced by Check-Mate Industries under direct military contract; and state-compliant 5 and 10-round options. Every magazine is USGI-specification steel with phosphate corrosion- resistant finish.
M14 / M1A Magazines at Keep Shooting
Keep Shooting carries authentic M14 and Springfield Armory M1A magazines — American-milled steel feed systems for one of the most accurate semi-automatic .308 / 7.62 NATO battle rifles ever fielded. Our catalog includes Taiwan T57 20-round military-issue surplus magazines from the Republic of China Army service rifle program, Springfield Armory M1A 5-round and 10-round magazines produced by Check-Mate Industries as Springfield's OEM supplier, and state-compliant reduced-capacity options for customers in jurisdictions that cap magazine capacity at 10 rounds.
The M14 magazine is one of the most historically significant service magazines ever designed in the United States. The design was finalized by John C. Garand himself — the inventor of the M1 Garand — in the first five months of 1954, while Garand was working as a consultant to Mathewson Tool Company on the T44E4 rifle contract that would eventually become the M14. Garand borrowed the magazine geometry from his earlier T31 rifle project, giving the M14 magazine a direct design lineage back to one of the most legendary American firearms engineers of the twentieth century. The M14 itself was adopted as the US military's standard service rifle in 1957, replaced the M1 Garand in combat service from 1959 onward, and remained in limited US service as the M21 and M25 designated marksman rifles and as the Mk 14 Enhanced Battle Rifle all the way into the post-9/11 era — meaning Garand's 1954 magazine design has been in continuous US military service for more than seventy years.
Our Taiwan T57 M14 Magazine is authentic Republic of China Army surplus. The T57 is the Taiwanese-produced M14 variant manufactured by the 205th Arsenal under a US technology-transfer agreement that began in the mid-1960s, issued as the standard infantry rifle of the Republic of China Army from 1968 until it was gradually replaced by the domestic T65 and later T91 rifles. Taiwan produced T57 rifles and magazines to US military specifications for decades, and the magazines from that program are functionally identical to USGI production — same dimensions, same spring tension, same USGI-pattern follower geometry. Taiwan T57 magazines are typically the best-value 20-round M14 option on the US market, since they are legitimately GI-specification steel at surplus pricing.
Our Springfield Armory M1A magazines are current-production Check-Mate Industries magazines marketed under the Springfield Armory name. Check-Mate Industries of Long Island, New York is the original-equipment manufacturer for Springfield Armory M1A magazines and has held US military contracts for M14 magazine production for more than thirty years — Check-Mate made the fresh- production M14 magazines supplied to US Navy deck rifles during the Gulf War, and the same manufacturing line continues to produce commercial M1A magazines today. Check-Mate magazines are made from American-milled steel, finished in mil-spec phosphate for corrosion resistance, and built to the same USGI specification that Garand finalized in 1954. The Springfield Armory branding on the magazine body denotes that the magazine has passed Springfield's QC process as a factory- authorized accessory.
M14 vs. M1A compatibility: The M1A is the civilian semi-automatic version of the M14 — Springfield Armory Inc. released it in 1971 as a commercial semi-auto built on an investment-cast AISI 8620 alloy steel receiver (vs. the forged receiver of the military M14). Mechanically, the magazines are fully interchangeable: any GI-specification M14 magazine will fit and function in a civilian M1A, and vice versa. The only functional difference is the absence of a full-auto selector switch on the M1A — a receiver feature that does not affect magazine compatibility at all. This means Taiwan T57 surplus, Check-Mate-produced Springfield M1A magazines, and any USGI M14 magazine you may encounter in surplus channels are all interchangeable between the two rifles.
7.62 NATO vs. .308 Winchester: The M14 and M1A are chambered in 7.62×51mm NATO. The 7.62×51 NATO cartridge has the same external dimensions as the commercial .308 Winchester, but NATO-spec ammunition is loaded to a lower maximum chamber pressure (50,000 psi NATO vs. 62,000 psi SAAMI .308 Win). It is generally safe to fire quality commercial 7.62 NATO ammunition in an M1A, and most modern M1A rifles are rated by Springfield Armory for both cartridges, but shooting hot-loaded commercial .308 Winchester ammunition in an M14/M1A can accelerate bolt wear and operating-rod peening over time. Check your specific rifle's documentation, and favor 7.62 NATO or M14-rated .308 Win loads for extended service life.
State capacity restrictions apply: Fourteen US states plus the District of Columbia restrict magazine capacity under state law. Most cap at 10 rounds (California, Connecticut, Hawaii, Maryland, Massachusetts, New Jersey, New York, Vermont rifle, Washington, DC); Colorado caps at 15; Delaware caps at 17. Customers in restricted states can purchase our 5-round M14 Magazine or 10-round M14 Magazine (or the Springfield M1A 5- and 10-round variants when in stock) — both are purpose-engineered reduced-capacity magazines with correct internal geometry, not aftermarket-blocked 20-rounders. Customers are responsible for verifying their local magazine-capacity law before ordering any magazine exceeding 10 rounds.
For alternative 7.62 NATO semi-auto platforms, see the AR-10 Magazines category (the Stoner-family SR-25 pattern competitor to the M14) and the FN SCAR-17 Magazines category (FN's 2000s SOCOM battle rifle). Note that M14, AR-10, and SCAR-17 magazines are all mutually incompatible despite sharing 7.62 NATO chambering. Browse our full Rifle Magazines hub for all semi-auto rifle platforms, and the Maglula M14 LULA is essential for loading M14 magazines efficiently — the stiff M14 spring is one of the most punishing in commercial shooting.
