ineffective and was usually replaced by an aftermarket Colt AR-15/M16 A2 "birdcage" model by owners. The loose tolerances for the magazine well could allow the magazine to move up inside it when the bolt was pulled to the rear, causing potential feeding jams. The chamber was sometimes too tight on early models, causing a failure to extract. Later models made by AAA were made to tighter tolerances and usually eliminated many of these problems. Company issues In 1982 St. George split from both Brian Shaw and Jack Allan and moved on and established Armtech Pty Ltd. The company folded in 1983 and the patents held sold to Australian Automatic Arms. Australian Automatic Arms (AAA) Leader Dynamics was subsequently sold off to a businessman who formed his own company, Australian Automatic Arms, and started to make the Leader rifles in Tasmania. They differed in lacking the carrying handle of the Leader and coming with a 30-round magazine. The Semi-Auto Rifle (SAR) had a 16.25" [413 mm] barrel and synthetic stock. The Semi-Auto Carbine (SAC) had a 10.5" [266 mm] barrel and synthetic stock. The Semi-Auto Pistol (SAP) (dubbed the "Tasmanian Devil") was a pistol-gripped stockless version of the SAC. It came with a sling to brace it during firing. Only 700 were imported into the US before being banned in 1994. The Sporting Purpose 20 (SP-20) had a 20" [508 mm] barrel and wood furniture and was sold as a sport shooting and hunting weapon. The forend was a wooden version of the polymer forend and the butt had a semi-pistol grip with a rubber recoil pad. Semi-automatic rifles and shotguns were restricted in Australia in 1996 following the Port Arthur massacre (Australia). The Leader was soon after withdrawn from production.
