Special Features

• The LLV-4X 4.5 inch Competition Upper is the defining feature of the Mamba-X, housing a stainless steel barrel with a laser-hardened breech inside a Type III hard anodized aluminum shroud for a rigid, accurate, and lightweight assembly that outperforms a standard barrel setup
• The integrally machined universal red dot mount positions the optic as low as possible to the bore axis, reducing the gap between point of aim and point of impact for faster sight acquisition and quicker split times on the competition stage
• The optic mount is compatible with the Trijicon RMR, Vortex Viper, Vortex Venom, Vortex Razor, Sig Sauer Romeo 1 Pro, Romeo 3 Max, Romeo 3 XL, Leupold DeltaPoint, Burris FastFire, C-More RTS 2, C-More Slide Ride, JP Enterprises JPoint, and Shield Sights Mini Sight, giving competitors the freedom to run the optic they are already comfortable with
• Pre-installed filler screws keep all unused optic mounting holes clean and protected when a particular footprint is not in use
• The Volquartsen Accurizing Kit transforms the stock Ruger MK IV trigger group into a crisp, light 2.25 lb break, delivering a level of trigger performance that directly supports accurate, consistent shooting in both practice and competition
• The DLC coated Volquartsen Competition Bolt reduces friction and wear on critical cycling surfaces, ensuring smooth and reliable feeding through the longest range sessions
• The upgraded Volquartsen magazine release paired with the included magazine base pads raises the magazine higher in the frame, allowing the bolt to positively strip and feed each round and eliminating the feeding inconsistencies associated with a stock MK IV setup
• The push-button takedown system inherited from the Ruger MK IV platform allows the pistol to be field stripped quickly and without tools for hassle-free cleaning and storage
• Made in the USA at the Volquartsen facility in Carroll, Iowa

• The broad optic compatibility means this pistol can grow with the shooter, accepting upgrades or optic changes without requiring a new mount or additional machining
