About the SMLE No.1 Mk III
The SMLE No.1 Mk III is a bolt-action rifle chambered in .303 British, produced by Lithgow Small Arms Factory since 1907. Featuring a 10-round magazine capacity, this rifle offers adequate firepower for defensive carry. The striker-fired action provides a consistent trigger pull for every shot, simplifying training and reducing the manual of arms - a design philosophy that has become the dominant paradigm in modern defensive handguns. The 25.2-inch barrel maximizes accuracy potential and ballistic performance, making this an excellent choice for target shooting, competition, or field use. At 3900g (137.6 oz), this is a substantial firearm whose weight contributes to reduced felt recoil and enhanced stability during precision shooting. The steel frame provides a solid, premium feel with the durability to withstand decades of regular use and thousands of rounds. This firearm represents its manufacturer's commitment to delivering a well-engineered, reliable product that serves the needs of discerning shooters seeking quality, accuracy, and dependable performance from a proven platform.
During the 'Mad Minute' test at Hythe in 1914, Sergeant Instructor Snoxall set the record of hitting a 12-inch target at 300 yards 38 times in one minute using the SMLE's lightning-fast bolt action-a rate of fire so rapid it led German soldiers at Mons to believe they were facing machine guns rather than riflemen.

The Mk III was adopted in 1907 as an improvement over the earlier Mk I, featuring a simplified rear sight, fixed charger guides, and a lighter nose cap. The Mk III* variant introduced in 1916 further simplified production by eliminating the magazine cut-off, windage adjustment on the rear sight, and the long-range volley sights. Lithgow Small Arms Factory in New South Wales was the primary Australian manufacturer, achieving peak production of 30,500 rifles in the 1915-16 financial year. Other major manufacturers included the Royal Small Arms Factory at Enfield, BSA in Birmingham, and the Ishapore Rifle Factory in India. Lithgow ceased SMLE production in 1953, with a final commemorative run of 1,000 rifles in 1956. The stock material is walnut.
