Swiss Schmidt-Rubin Straight-Pull Rifle Database

An exceptional piece and the absolute worldwide reference in submachine guns: the Heckler & Koch MP5A5 in 9x19 Parabellum, factory full-auto configuration with metallic retractable stock. This used example comes from a police service and ships with its full duty kit: transport bag, magazine, 3-point sling, tactical light, and B&T Picatinny rail.

The MP5 is the most produced and most widely used submachine gun in the world since the 1960s. Designed by Heckler & Koch on the basis of the G3 rifle's roller-delayed blowback system, it has equipped and still equips law enforcement agencies, tactical intervention units, special forces and armed forces across more than 90 countries. Its mechanical reliability, its remarkable accuracy for the category (roller locking, closed-bolt firing) and its field-proven ergonomics make it a truly exceptional firearm sought after by authorized collectors and shooters.

The MP5A5 variant — identified by its retractable stock and its Navy trigger group (S/E/2/F or S/E/F depending on variant) — is the standard for intervention units. It offers the best compromise between compactness (transport and maneuvering in confined spaces) and firing stability (stock deployed), while retaining the full-auto option for critical tactical scenarios.

• Global reference submachine gun: the MP5 is THE most widely used SMG platform by tactical intervention units for 60 years (GIGN, GSG-9, SAS, Navy SEALs, LAPD SWAT, DEVGRU, European police forces).
• Factory full-auto: original military/police configuration, no civilian conversion. Authentic historical piece.
• HK roller-delayed blowback: iconic system derived from the G3, closed-bolt firing = remarkable accuracy for an SMG (tight groups at 25–50 m, exceptional recoil control in full-auto).
• A5 retractable stock: compactness for transport and CQB maneuvering, firing stability with stock deployed — the most versatile variant of the MP5 lineup.
• Ex-police provenance: a firearm with lived operational history, marked by service — strong appeal to collectors and duty-use enthusiasts.

• Heritage investment: authentic ex-service MP5s are becoming scarce — collection asset with strong appreciation potential.

This example served in a police service. The firearm shows usage marks consistent with operational duty (scratches, patina on the phosphate finish, handling marks), but remains in perfect mechanical operating condition. It has undergone a full gunsmith inspection prior to sale: locking mechanism, selector, trigger, recoil spring, bolt carrier, gas system, barrel and sights — everything is functional and compliant.
