Overview

The De Lisle Commando Carbine is a British integrally suppressed bolt-action carbine developed during the Second World War for clandestine and commando operations. Chambered in subsonic .45 ACP, it mated a modified Lee-Enfield No. 1 Mk III bolt action to a Thompson submachine gun barrel and a large integral suppressor running the full length of the weapon. The suppressor was so effective that the bolt cycling was reportedly louder than the muzzle report, making it one of the quietest firearms ever issued. It fed from a modified M1911 magazine and was prized for silent elimination of sentries.

Production

Estimated total produced: 130 · Production years: 1942-1945

Origin

Country of origin: United Kingdom

Designer: William Godfrey De Lisle

Discontinued: 1945

Notes

The integral suppressor occupied nearly the full length of the weapon, so the apparent barrel is mostly suppressor with a comparatively short rifled section. Subsonic .45 ACP avoided the supersonic crack of conventional rifle rounds, and there was no visible muzzle flash. Most examples used a 7-round magazine; some references cite optional 11-round magazines.

Background

Designed by William Godfrey De Lisle, the carbine was reportedly tested before Winston Churchill and proved so quiet that the loudest sound was the click of the bolt. It claimed its share of sentries and officers in commando raids, and a folding-stock airborne version was developed for paratroopers though never widely issued.
