British Factory Sterling MK5 L34A1 9x19mm NATO Integrally Suppressed Pre-May Dealer Sample Only Sub Machine Gun

Status: SOLD


This Chester County Armory listing is for an original,  British factory-made and US imported,  Sterling MK5 (Mark V) L34A1 9x19mm NATO integrally suppressed Pre-May Dealer Sample Only sub machine gun.

Arguably, one of the quietest and most reliable integrally suppressed sub machine guns ever designed (some will argue even quieter and softer shooting then the most recognized in this class, the venerable MP5SD), the Sterling MK5  (or L34A1, as it is known by its British military designation) was one of the first sub machine guns adapted specifically for covert use by inclusion of a ported barrel and an integrated suppressor.  Even though the Mark 5 continues use of the Sterling’s original open-bolt design, the pairing of the side breech opening, ported barrel, and suppressor makes for one of the quietest models ever designed.

This Pre-May Dealer Sample Only machine gun is completely British factory-made by Sterling and imported was imported by Lanchester USA in Dallas, Texas. As a post-1968, pre-1986 imported machine gun, it is only available as an FFL Dealer Sample model. Serial numbers of both the Sterling suppressor, as well as the Sterling machine gun, are matching. This model contains all appropriate Sterling UK patent information on the underside of the magazine well, in addition to British Military-correct L34A1 marking on the top of magazine, next to the MK5 model designation.

This weapon is in fantastic mechanical condition, with no wear concerns whatsoever. The bolt-face is clean and the bolt assembly notes no wear marks other than what is to be expected from normal metal-to-metal contact. The bore is bright and shiny with crisp and clean rifling.  The metalwork is perfect, with no cracks, dents, dings, gouges, malformations, etc.

Cosmetically, this Pre May Dealer Sample machine gun is also in wonderful condition. The original black crinkle finish is in excellent condition, with no noted handling marks. The wooden handguard is in wonderful condition with no cracks, no noted wear, and only minor handling marks in the wood. All folding and physical mechanisms lock and move appropriately. It will come with one 34rd factory Sterling magazine.

This Pre-May Dealer Sample Only sub machine gun and suppressor are both currently on Form 3’s for easy transfer. This weapon will require two Form 3 transfers, one for the machine gun and one for the suppressor. Both items are Pre-May Dealer Sample Only items.
