Volquartsen Pistol Lineup: Mamba, Black Mamba, and Scorpion

The Volquartsen Mamba is the flagship carry and range pistol — a .22 LR semi-auto built on a Volquartsen-designed receiver with a 3.5″ threaded barrel, adjustable trigger, and exceptional fit-and-finish. The Black Mamba adds a compensator and extended barrel for competition use. The Mini Mamba compresses the platform into a 3″ threaded package for suppressor-focused shooters. All share Volquartsen’s hallmark: triggers that break at under 2 lbs with no creep, and barrels that consistently hold 1″ groups at 50 yards. These are not budget rimfire pistols — they are precision instruments.

Volquartsen Uppers for Ruger Mark IV and S&W Victory

For shooters who own a Ruger Mark IV or Smith & Wesson Victory, Volquartsen produces drop-in replacement uppers that transform a good rimfire pistol into a great one. The Volquartsen LLV-4 upper for the Mark IV replaces the entire barrel and receiver assembly, providing Volquartsen’s precision barrel with a modified profile optimized for competition sighting systems. The I-Fluted upper for the S&W Victory delivers similar results on that platform. These upper swaps offer a significant performance upgrade at a fraction of the cost of a complete Volquartsen pistol.

Volquartsen for Rimfire Competition: Steel Challenge and RFRO

Steel Challenge and Rimfire Open (RFRO) competition has become one of the fastest-growing shooting sports in the country — affordable, beginner-friendly, and genuinely fun. Volquartsen pistols and uppers are the dominant equipment choice in the top divisions because the combination of a sub-2 lb trigger and a precision barrel produces measurably faster splits and more consistent hits on steel. For a shooter entering rimfire competition, a Volquartsen upper on an existing Mark IV is the most cost-effective path to competitive equipment. For serious competitors, a complete Volquartsen pistol is the benchmark.

Volquartsen for Suppressor Use: The Best .22 LR Host

Every Volquartsen pistol ships with a threaded barrel — typically 1/2×28 for .22 LR — making them first-class suppressor hosts. The Volquartsen action cycles reliably with subsonic ammunition, and the precision barrel produces the consistency needed to hear the difference between good and great subsonic loads. Since January 1, 2026, the NFA $200 tax stamp has been eliminated, making suppressor ownership dramatically more accessible. See our suppressors page for compatible .22 LR cans.

Volquartsen vs. Ruger Mark IV: When to Upgrade vs. When to Buy New

A factory Ruger Mark IV is an excellent rimfire pistol. A Volquartsen-upgraded Mark IV is a competition-ready precision instrument. The decision point is use case: for casual range use and plinking, the factory Mark IV is entirely sufficient. For competition, suppressor use, or a buyer who wants the best rimfire trigger available, a Volquartsen upper or complete pistol is the right investment. Volquartsen components also hold their value extremely well — a used Volquartsen upper commands close to retail price, making them a reasonable investment for serious rimfire shooters.
