This vintage B. Müller Rifle & Pistol Conversion Kit will allow for the shooting of 4mm lead BBs in the Swiss Schmidt Rubin rifle Models 89, 1911, K11, K31 and the Swiss Luger pistols chambered in 7.65mm (7.65x21mm para / .30 Luger). Unlike the Lienhard conversion kits the Müller system used 4mm Flobert Rimfire Cartridges eliminating the need for accessories to hold the primer and ball (BB).
Though the Müller system never achieved quite the popularity of the Lienhard Conversion Kits they are still highly prized by collectors and valued by shooters wishing to practice at a lower cost.
This kit appears to be complete. It is difficult to evaluate as comparable examples are often seen with either less or more parts. These kits did get used so it is very common the prior owner would lose parts or add tools as needed. What is shown in the photos is what will be received.
This kit includes:
Box – good condition, some wear, two corners with tears
Instruction Manual (German)
Assortment of Targets
2 – Metal Tins – 4mm Flobert Cartridges and lead BBs
1 – Cleaning Brush
1 – Cleaning Rod
1 – Cleaning Rod with extension
1 – Cartridge Tool
1 – Loading Tool
1 – Barrel (Pistol)
1 – Barrel (Rifle)
Both Barrels feature good bores with solid rifling but some wear and fouling
Please note, most of the copper cartridges in the tin appear to have been fired. 4mm Flobert Rimfire Cartridges are still made to this day and can be found with and without ball.
