At a Glance:

  • Fully metallic lower replacing factory plastic

  • Fully assembled and upgraded with all TANDEMKROSS parts and accessories

  • “Drop-in” ready out of the box

  • Not serialized! Does not require an FFL

  • Compatible with virtually ALL factory or aftermarket Ruger® Mark IV™ and Mark IV™ 22/45™ uppers


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 Additionally, the takedown button has been replaced by a single takedown screw that helps preserve the pistol’s simple takedown while reducing play between the lower and upper for a firm, secure hold.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:


Choose your favorite color Kraken and all black or all red accessories! Plus, by choosing to add an Accelerator Forward Thumb Ledge to your #TANDEMIZED Kraken you’ll save $10!

Kraken
I have been shooting my Kraken weekly for a month now. I really like how it feels in my hand, the ledges and trigger guard configuration are great. The mag release works very well also. I've tried 3 MKIV uppers without issues. The trigger pull is very light. So far I'm very happy with my Kraken!

TANDEMIZED Kraken
Just received the Kraken. It is wonderful! I mounted a Volquartsen barrel and bolt to make a great pistol. I had a couple questions and Tyler answered them immediately. I’ve been dealing with Tandemkross for many years. It has been a real joy!

Kraken Complete Lower
As a long-time admirer of the Ruger Mark Series I had it in my head to finally make the leap. Thanks to previous experience with Tandemkross while upgrading other pistols I was positive the Kraken would be everything I hoped for in turnkey fashion, and TK did not disappoint! The Kraken just feels like a whole other pistol when compared to an OEM lower. Comfortable with ergonomic controls, beautiful machining, and finish. Trigger pull weight is superior, the shoe itself is comfortable. I could gush for days! Despite the step up in price the case can be made that [TK]’s all in one solution is a far better bargain than a factory Mark, particularly if you’re looking to upgrade your barreled upper with an aftermarket. First range outing was outstanding, far exceeding my already heightened expectations. If you find yourself at a crossroads while in want of a Mark IV, do yourself a favor and order a Kraken.

Tandemized Kraken is a Winner
This lower is outstanding! Every item on it is superb. Most important, it makes shooting so much better. The trigger is about 1.9 lbs! WOW! Buttons are a litter larger and very easy to reach. All in all, this is a superb lower for the Ruger Mark IV 22/45 Lite.
