SPF: Sterling MK5 ( L34A1 ) – DLO / Andrewski / KGB Armament – Transferable SMG – 9mm

panhead57 · January 4

The host gun for this awesome Sterling MKV – L34A1 - transferable 9mm SMG was built on a virgin DLO tube by John Andrewski and the suppressor and finishing touches were added by KGB Armament. For MK5 suppressors, KGB is considered one of the best as they build the closest thing to a factory MK5 available on the market. The exterior of a KGB MK5 is absolutely indistinguishable from a factory MK5 (except for the DLO Sterling tube markings), right down to details like the length that the end cap hex screws protrude out the muzzle end of the gun. KGB also upgrades the internals to produce a more reliable, cleaner running, and quieter weapon than the factory MK5. Another very desirable feature of KGB's suppressor design is that it can be easily disassembled by the user for cleaning. KGB recommends field-stripping and cleaning the suppressor every 1500 rounds and has produced a good video with instructions on their recommended procedures. The ported barrel of this MK5 was optimized to reduce the velocity of standard 115/124 grain 9mm ammo from supersonic to subsonic levels, thus eliminating sonic crack for ultra quiet operation. The gun is used, in excellent condition, with less than 800 rounds fired.

The Sterling MK5 is one of the quietest and most reliable integrally suppressed submachine guns ever produced (many claim it is even quieter and softer shooting than the esteemed MP5SD, even though the MK5 fires from an open bolt). The MK5 (British military designation L34A1) was one of the first submachine guns designed specifically for covert use by using a ported barrel and an integral suppressor. The MK5 wasn't originally intended to be fired enough to get very hot, therefore, the British Army deemed it unnecessary to use an insulated foregrip. Wooden foregrips were unique to commercial and export models of the MK5. While this MK5 was built similar to the military models, a new wooden foregrip will be included with the sale should a Buyer prefer that configuration.

Two Scope Studs were added to this MK5 during the build to accommodate the use of optics. A custom Picatinny rail made by Andrewski that mounts on the two scope studs is included to accommodate the use of a wide variety of optics. A Trijicon compatible mount that attaches directly to one of the scope studs is also included for those who don’t want to use a picatinny rail. The Trijicon red dot sight shown in some of the pictures is not included in the sale. The sale also includes two (2) unused, still in the wrapper, original 34 round magazines and a quad picatinny adapter that mounts over the suppressor to accommodate items such as IR lasers, etc. The last 4 digits of the SMG, Suppressor, and Magazine Block's serial numbers match (“80 014X”, “014X”, and "014X").

This is a 2 Stamp gun, one for the Suppressor (KGB), and one for the SMG (DLO). Both are on Form 4s in Texas. As these are Class III/NFA items, if a Buyer is in Texas, after Form 4 approval, the items can be transferred directly to him/her. For non-Texas buyers, the items must be transferred to a Class 3 / SOT licensed dealer in his/her state. Buyer is responsible for finding a local FFL/SOT dealer to handle the transfers.

Please send PM with any questions or to request additional pictures. I also have a couple of videos of this MK5 being fired.

Buyer pays transfer taxes, plus shipping and insurance via USPS Registered Mail. Price is $32,500.
