It has been RELEASED!


The TANDEMKROSS "Kraken" aluminum lower (commonly referred to as a "stripped lower") is designed to take the internal components from your polymer lower and install them in your all new, deluxe lower upgrade!


The “Kraken” is built to last! This light and durable aluminum lower is highly heat and chemical resistant. Fully metallic - no more ripping thread inserts out of your frame! 


The “Kraken” features a textured back-strap for a more slip resistant surface no matter the conditions. This in combination with a larger, "hooked" trigger guard provides enhanced ergonomics for improved grip and control. Also the oversized trigger guard is ideal for gloved hands!

Over time the engagement of the Upper and Lower of the pistol can loose its secure seating resulting in unwanted play between the frame and the upper. We have removed the one button takedown in favor of a redesigned and upgraded mainspring housing. The unique proprietary locking mechanism will improve the interface between the lower and upper, creating a more tight and secure fitment. All this makes your pistol more reliable and dependable. 

Tandemkross-Kraken-Back
Anyone who has fully disassembled and reassembled a Mark IV™ 22/45™ knows that the installation of the sear can be the most frustrating part of the process - The intuitive design of the "Kraken" Lower makes installation of the sear simple with a sear retention hole; designed to allow the sear to be held in place with the included 1/16” allen wrench until the hammer assembly is installed.

We have also included an internal feature to limit how far the hammer can lean back. This feature will ensure the hammer is never cocked over center - eliminating a common headache during installation.

The “Kraken” supports virtually all [TK] parts and accessories for the Ruger® Mark IV™ 22/45™. This lower will also host practically all stock and aftermarket and factory uppers for the Ruger® Mark IV™ and Mark IV™ 22/45™. 


The “Kraken” Aluminum Lower for the Ruger® Mark IV™ 22/45™ is an absolute must-have for shooting sports competitions or to simply... MAKE YOUR GOOD GUN GREAT!

Exactly what I needed to complete the build
absolutely great frame with much tighter tolerances than the factory polymer frame. This is exactly what I needed to finish out my build. Everything went together as smoothly as possible for a Mark IV 22/45. The sear assembly is still just as infuriating as normal with the VQ sear, as it doesn't benefit from the hole in the frame that TandemKross put there. the sear and hammer spacers used with the VQ kit are no longer necessary with this lower due to the tighter tolerances. Paired this frame with an LLV upper and competition bolt from Volquartsen, TandemKross Victory Trigger, TandemKross grips, Striplin thumb ledge, and cornerstone safety. It's a killer setup and having the aluminum frame really completes the build in a way the factory polymer couldn't. Now it actually feels like a high end custom gun.
