As a result, Springfield Armory designed a muzzle brake, which they installed in place of the standard flash suppressor on all models that were sold in California. The California Assault Weapons Ban prohibits flash suppressors on all semi-automatic rifles capable of accepting a detachable magazine. Since the bayonet lug is attached to the flash suppressor, "post-ban" rifles can easily be fitted with a bayonet lug by fitting a pre-ban flash suppressor. Although the 1994 law expired in September 2004, making bayonet lugs on newly manufactured firearms legal again (in most states), Springfield Armory has not restored that feature.

Once the Federal Assault Weapons Ban of 1994 was passed prohibiting the manufacture of firearms with bayonet lugs (among other features), the M1A no longer shipped with a bayonet lug. Springfield Armory has also omitted the "7.62-MM" caliber designator on the M1A receiver since 1991. Until around the late 1990s, the M1A produced by Springfield Armory retained the cutout in the rear right of the stock for the selector switch found on the M14. The military M14 receivers were manufactured using the drop forge process, which is more complicated and more expensive. M1A receivers are made from precision investment cast AISI 8620 alloy steel. Selector switch cutout in M1A stock manufactured in 1997 There are, however, a few important differences: The Springfield Armory M1A is, for the most part, identical to the M14. It proved to be an impossible task to replace all four as the cartridge was too powerful for the submachine gun role and the weapon was too light to serve as a light machine gun replacement for the BAR. It was thought that in this manner the M14 could simplify the logistical requirements of the troops by limiting the types of ammunition and parts needed to be supplied. The M14 was developed to take the place of 4 different weapons systems: the M1 Garand, M1 carbine, M3 submachine gun, and M1918 Browning Automatic Rifle (BAR). Robert Reese bought Springfield Armory from Elmer Ballance, and moved the manufacturing to Geneseo Ill in 1974.ĭifferences between the M1A and M14 Early M1A rifles were built with surplus G.I. "M1A" is a proprietary name for Springfield Armory's M14-pattern rifle. The Springfield Armory M1A is a semi-automatic rifle made by Springfield Armory, Inc., beginning in 1971, based on the M14 rifle, for the civilian and law enforcement markets in the United States.
