The Volquartsen Mamba LLV Competition Upper 4.5" is purpose-built for anyone serious about accuracy. This replacement upper swaps onto any Ruger Mark IV frame in minutes, giving you a complete overhaul without buying an entirely new pistol.
The engineering here is straightforward but effective. Volquartsen machines the receiver from a single piece of Type III hard-anodized aluminum to minimize weight while maintaining structural integrity. Inside that lightweight housing sits a stainless steel match-grade barrel with a honed and lapped bore. The result is a 4.5-inch upper that feels balanced in your hand and groups shots tight enough for serious competition or precision target work.
Unlike some lightweight designs that cut corners, the LLV-4 features a stainless steel breech face engineered to handle thousands of competition firing cycles. The receiver comes topped with a Picatinny rail for optics mounting, and the barrel is threaded 1/2×28 TPI to accept suppressors or other muzzle devices. You get a thread protector in the box to keep those threads protected until you're ready to add accessories.
This is purely the upper receiver assembly. It installs on any standard Ruger Mark IV grip frame using Ruger's straightforward push-button disassembly system. The receiver and barrel shroud are precision-machined together as one piece, ensuring perfect alignment and consistent accuracy from shot to shot. Whether you're into iron sight competition, running a dot sight, or building your personal precision rig, the LLV-4 gives you a platform that punches well above its weight.
Yes, this upper receiver installs on any standard Ruger Mark IV grip frame. The push-button disassembly system on the Mark IV makes installation straightforward. You're simply swapping the upper receiver, so installation takes just a few minutes without tools.
Yes. The barrel is threaded 1/2×28 TPI, which is a standard rimfire suppressor thread pattern. The upper ships with a thread protector to keep the threads safe until you install a suppressor or other muzzle device. The thread protector is removable.
The stainless steel match-grade barrel with a honed and lapped bore is capable of producing tight groups. Many users report dime-sized groups at 25 yards with quality ammunition. Actual accuracy depends on your setup, technique, and ammunition selection, but this upper is engineered for precision competition use.
Yes, this competition upper works with both standard Mark IV and Mark IV 22/45 frames. The 22/45 frame uses the same push-button disassembly system, making it just as easy to install.
