The Rifle 7.62 mm 1A1 which is also known as Ishapore 1A1, is a copy of the UK L1A1 self-loading rifle.
It is produced at Ordnance Factory Tiruchirappalli of the Ordnance Factories Board.
It differs from the UK SLR in that the wooden butt-stock uses the butt-plate from the Lee–Enfield with trap for oil bottle and cleaning pull-through.
The 1A1 rifle has been replaced in service with the Indian Army by the INSAS 5.56 mm assault rifle.

A fully automatic version of the rifle (known as the 1C or  Ishapore 1C ) is also available, meant for use in BMP-2s via firing ports.
The 1A1 is still in use by Central Armed Police Forces, some law enforcement bodies and also used during parades by the National Cadet Corps (India).

The 1A (which is also known as Ishapore 1A), is the full automatic version based on the FN FAL while the 1A1 (which is also known as Ishapore 1A1), is the semi-automatic version based on the L1A1.
They can be equipped with the 1A and 1A Long Blade bayonet, based on the L1A4 bayonet.

Production started in 1960 after the Armament Research & Development Establishment (ARDE) evaluated several Australian, Belgian and British FAL rifles and each one was disassembled and examined.
ARDE researchers began to make plans to make their own rifle after negotiations with FN were unsuccessful because of royalty requirements and the clause that Belgian technicians help manage the production lines.
750 rifles were made per week.

FN threatened a lawsuit when they learnt of the unlicensed variant.
Then Prime Minister Jawaharlal Nehru was not made aware of it and after he had heard it, offered to settle FN's complaints by agreeing to purchase additional Belgian-made FALs, FALOs and MAG 60.20 GPMGs.

In 2012, around 6,000 rifles were made annually in India.
As of September 2019, around a million rifles were made.
