Lose the lower half of your Ruger 22/45 MkIV in a tragic boating accident? No worries, Tandemkross has the Kraken lowers to suit all of your aftermarket needs!
Company Info: TANDEMKROSS
Tandemkross describes themselves as a company manufacturing “performance parts that solve common firearm problems. Competition shooters and weekend plinkers alike benefit from [TK].”
The company is based out of New Hampshire – and unironically located only about 45 minutes to an hour from Ruger Investment Castings. Unironically, because their first product was a hammer bushing that removed the annoying magazine disconnect from the Ruger Mark III pistols. Ten years later, Tandemkross has gone from a small cottage industry brand making a few doodads to a company making a name for itself in the rimfire market and beyond.
Product Info: Kraken Aluminum Lower for Ruger 22/45 Mark IV
With another Ruger Mark series pistol comes another generation of products to improve, upgrade, and otherwise modify a budget blaster into a Gucci gear rimfire pistol that even 22Plinkster was proud to build and use.
The Kraken seems to solve one of the Ruger 22/45 MkIV’s only potential problems. flex and slop in the rear mount of the receiver to the lower due to the push button quick release. While this does require an allen screw to clench and tighten up the lower and upper together, it does increase the security of the two portions combined. With it, it is reported it gets rid of the wobble and “keychain rattle” some stock 22/45 MkIV’s have.
Having the ability to start from a frame-up and swapping your OEM parts or using Tandemkross’s BYOK (Build Your Own Kraken) give you the option to create a lower built to your specs.
Other Products
Upgraded Magazine Release KrossPins for Ruger® 10/22® (2-Pack) – Currently have medical tape over one of my pins on the trigger housing for when I have to clean the bolt. So glad this was made.
Steel Hammer Bushing for Ruger® MKIII™ and MKIII™ 22/45™ – The product that started them all. Bought this guy early in TK’s history, along with the MkIII LCI replacement. Sure did class up my 22/45 LITE. ?
Observations
TK knows what they’re doing. This Kraken lower receiver grip is definitely for a market of buyers focused on competition, flexing on the poors, or wanting to eek out every inch of what the 22/45 MkIV platform can do.
While I didn’t get to fire the pistol with the lower on it, I could tell this was a sturdy piece, and with all the reliability in products I have purchased from Tandemkross in the past, I have little doubt about this lower.
Keep any eye out for Luke Cuenco’s posts, I believe he is going to be receiving one of these to play with.
