Also known as: De Lisle Commando Carbine, De Lisle Silent Carbine

Overview

The De Lisle carbine is a British bolt-action integrally suppressed carbine developed during World War II for commando and special-forces raids. Built on a modified Lee-Enfield SMLE action rebarrelled for the subsonic .45 ACP pistol cartridge and fed from adapted M1911 magazines, its large integral suppressor makes it one of the quietest firearms ever produced. Only around 130 were built, seeing clandestine use with British Commandos and the Special Operations Executive.

Notes

Roughly 17 prototypes were built by the Ford Motor Company at Dagenham; the bulk of production (about 129 examples) was completed by the Sterling Armaments Company. A folding-stock 'Airborne' variant was prototyped for paratroop use but not mass-produced.

Background

So quiet that the loudest sound was the firing pin striking the primer, the De Lisle registered around 85 dB on test - quieter than many modern suppressed rimfires - letting commandos take out sentries without alerting nearby troops.
