Aluminum grip frame with cerakote finish increases durability and strength
Single takedown screw replacing button increases firm anchor to upper for reliability
Supports factory and aftermarket uppers for Ruger® Mark IV™ and Mark IV™ 22/45™
The TANDEMKROSS Stripped “Kraken” Grip Frame is designed to work with virtually all factory or aftermarket internal components of a Ruger® Mark IV™ 22/45™. Convert your parts from your polymer, factory lower to this lightweight, durable, metallic upgrade!
“Krakens” are built to last! Made from aluminum with a stylish cerakote finish, this stripped grip frame is highly resistant to heat, chemicals, and general wear and tear. Thanks to the entire frame being aluminum, there is no more need to fear ripping out your brass thread inserts when removing your grip panels for routine maintenance.
TANDEMKROSS’s aluminum grip frame upgrade also boasts a textured backstrap and enlarged and hooked trigger guard. These ergonomic improvements improve the ability to securely grip your pistol and make shooting easier in any condition for hands of all sizes, gloved or not.
While a simple takedown button was a huge value add to the Mark IV™ over the Mark III™, TANDEMKROSS’s engineers saw an opportunity to increase reliability and performance. A single takedown screw is still a common concept on many popular firearms like the Ruger® 10/22® or Smith & Wesson® SW22 Victory®. While it adds the need for a tool, it still keeps the overall takedown process short and sweet. Additionally, this allows for a more firmly anchored engagement between the upper and lower. This method preserves not only the simplicity of your pistol, but the long term reliability as well.
Improved performance and reliability are nice, but the “Kraken” was engineered with even more than that in mind. Thanks to the intuitive design of this aluminum lower, installing the sear and hammer is now easier than ever. Using the sear retention hole, you can hold your sear in place with the included 1/16in hex wrench until the hammer is full installed. There is then an internal feature that prevents the hammer from ever cocking over center, eliminating a common installation headache.
“Krakens” support virtually all TK parts and accessories for the Ruger® Mark IV™ 22/45™ and will host practically any factory or aftermarket uppers for both the Ruger® Mark IV™ and Ruger® Mark IV™ 22/45™.
Available in multiple colors with a flood of aftermarket support, the ways you can customize your pistol are practically limitless. The Stripped “Kraken” Grip Frame from TANDEMKROSS is an absolute must-have for any competitive shooter or plinker looking to get the most out of their favorite rimfire pistol. Get your “Kraken” today to make your good gun GREAT!
