Below is a description of each component.

Volquartsen Mamba-X LLV

This upper has it all for your Ruger MK IV. Not only is it extremely lightweight and well-balanced, but the accuracy is even better. How do we do that? We use a Type III hard anodized machined aluminum receiver to reduce the weight but then fit it with a stainless steel match barrel.

Our Mamba LLV Competition Uppers are unlike other lightweight designs. Even though it is lightweight, it still features a stainless steel breech to withstand the rigors of competitive shooting.

Volquartsen Competition Bolt

Are you a competitive shooter looking to eliminate stovepipes, failures to fire and improve the overall performance of your Ruger MKII, MKIII, or MK IV pistol? The Competition Bolt is the answer!

  • CNC-machined and ground for superior fit and finish
  • Includes Exact Edge Extractor and SureStrike Firing Pin
  • Includes our Recoil Rod with standard rate spring installed.
  • Extended Bolt Racker machined integral to the bolt for improved manual cycling of the bolt – no more pinched fingers!
      • Increased hardness
      • Low residual stress
      • Increased lubricity
      • Low coefficient of friction
      • Improved wear resistance
      • Requires much less lubricationCase hardened and then treated with DLC – a high performance premium finish that offers many advantages.
Tandemkross Cthuhlu/Kraken Grip Frame

The #TANDEMIZED Kraken is the single best way to get the most out of your Ruger® Mark IV™ Standard or 22/45™ pistol. What was once a stripped lower that required additional parts and assembly is now ready to host your pistol’s upper right out of the box! Increase the life and durability of your pistol while also increasing its reliability and performance!

TANDEMKROSS’s Kraken boasts an enlarged trigger guard for large or gloved hands, a hooked trigger guard for more points of contact, and textured backstrap for improved grip and ergonomics. Additionally, the takedown button has been replaced by a single takedown screw that helps preserve the pistol’s simple takedown while reducing play between the lower and upper for a firm, secure hold. The cerakoted aluminum is also much less susceptible to damage from heat, chemicals, impact, or general wear and tear.

Since all Ruger® Mark IV™ Standard and Mark IV™ 22/45™ pistols share the same one-button takedown feature, the Kraken will support virtually any factory or aftermarket Ruger® Mark IV™ or Mark IV™ 22/45™ uppers. This means the Kraken allows you to easily turn any Ruger® Mark IV™ into a Mark IV™ 22/45™. All you need is to swap out the factory Mark IV™ magazine base pads with Mark IV™ 22/45™ base pads. TANDEMKROSS’s extended magazine bumpers perfectly fit the bill! Try either the “Tomahawk” or “MarkPRO” Magazine Bumpers that both come in packs of two.

This upgrade contains over 30 parts, components, and accessories, all from TANDEMKROSS and all fully installed, assembled, tested, and ready to go as soon as it arrives at your door. Whether for serious competition or recreational plinking, the #TANDEMIZED Kraken is perfect for anyone looking to improve their favorite rimfire pistol.

With the #TANDEMIZED Kraken you’ll receive:

Accelerator Thumb Rest for Ruger® Mark IV™ 22/45™
Blast Pack
Bolt Keeper Extended Bolt Stop
Cornerstone Safety Thumb Ledge
Engraved Titanium Grip Screws (4-Pack)
Kraken Aluminum Lower
