A-Square

A-SQUARE COMPANY, LLC was a manufacturer of rifles, ammunition and bullets based in Chamberlain, South Dakota in the United States. The company was one of 19 that are members of the Sporting Arms and Ammunition Manufacturer's Institution. The company's focus was on its firearms for hunting large dangerous game. This was reflected in the selection of larger caliber chamberings in the company's rifles.

A-Square manufactured rifles usually came with stainless steel barrels as a standard feature. The barrels on the rifles use epoxy resin to bed the barrel to the stocks. Magazine boxes were manufactured from plate steel for rigidity and were also welded to the receiver. A-Square rifles were engineered to allow the firing pin to retract further into the bolt body than other firearms . This increases the force of the firing pin on the cartridge within the chamber.

Available calibres for A-Square firearms range from those designed for large, dangerous game (curiously including the somewhat obsolete .416 Taylor) through to smaller calibre rifles ( .243 Win).

A-Square also held the patent for the Monolithic Solid Bullet.
