Happy first birthday to the “Kraken” Aluminum Lower for Ruger® Mark IV™ 22/45™! To commemorate this momentous occasion, we are launching the new #TANDEMIZED “Kraken” now available for Ruger® Mark IV™ and Mark IV™ 22/45™.

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 Additionally, the takedown button has been replaced by a single takedown screw that helps preserve the pistol’s simple takedown while reducing play between the lower and upper for a firm, secure hold.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

Get the #TANDEMIZED “Kraken” for your Ruger® Mark IV™ or Mark IV™ 22/45™ today and make your good gun GREAT!

Your #TANDEMIZED “Kraken” is built to order and may require some extra time to assemble by our in-house customs shop. Please allow for as many as 3–4 weeks for full assembling and processing.

Don’t forget, all TANDEMKROSS products are made in the USA and come with a LIFETIME guarantee!

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!

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.
