D.S. Arms or DSA as they are commonly known as was founded and issued an FFL by BATFE in 1987.
D.S. Arms Inc. was incorporated in February 1992 in the State of Illinois and upgraded to class 07, 08 and 10 manufacturing and importing FFL’s.

D.S. Arms Inc. manufactures the (ENTIRE) FN FAL 7.62mm rifle system in the United States utilizing new tooling, improved materials and modernized processes.
DSA FAL rifles are completely interchangeable with the original F.N. metric FAL.
DSA also produces spare parts and proprietary accessories for the FAL.
DSA is not just a parts set assembler like others, but actually fabricates every FAL part in house and through carefully selected qualified long term vendors.

In addition DSA now produces the M16 series rifle and components which are supplied to OEM customers.
DSA produces 80% of the parts for the M16 and uses no imported parts on production rifles unless a foreign made accessory is specified by the customer.
As with the FAL, DSA is a true fabricator of the M16 type rifles.

They have also produced components under contract for M2 .50 caliber, MAG58 and M203 40mm.
The company has experience in many areas of fabrication, design and prototyping.
DSA is proud to provide U.S. based manufacturing jobs at a time when they are most needed.

DSA is a noted specialist in U.S. and foreign small arms weapon systems up to .50 caliber.
DSA offers training to the end-user for operation, maintenance and armorers courses for FAL rifles.
