Building the Kraken – Ruger 22 lower by Tandemkross

TriggerSnob - Gun Smithing 2022-01-13

TK just released the Kraken https://www.tandemkross.com/the-kraken-aluminum-lower-for-the-ruger-mark-iv-2245.html

With the BYOK Kit, you have everything needed to build a full lower. A donor frame/stock lower is no longer needed. Just build lower and pick upper of your choice.

The machining and fit and finish are top quality. The fit is TIGHT. I’ve built a few older Rugers and this was still a bit of a challenge. It was a fun project. The internals used the Volquartsen sear, but the TK trigger. A few tips:

  • mixed parts in the BYOK kit- maybe I mixed them up, but check the small BYOK kit on this pdf. 6/7 and 1/2 were swapped. Once that was identified, all GTG: https://www.tandemkross.com/assets/images/product-Rebuild_Kit_Ruger-Mark_IV-2245-Part_Chart.pdf
  • when putting in the safety and setting the hammer, you have to pull the trigger to allow the trigger bar to go down and then into the slot on the sear. Before I was pushing down like mad trying to get the hammer seated but it just wouldn’t go.
  • Put in the set screw into the trigger before installing, it will make it easier.
  • I still prefer the Volquartsen triggershoe.
  • the extended mag button is plastic, not metal, I will most likely make a metal replacement.
  • the extended safety is very good, better than expected.

  • CZ97 Old vs New - .45ACP Double Fisted FUDDRUNNERS

    by on 2022-02-19 - 0 Comments

    So, I got bored and made a new video about new(to me) old CZ97B Safety model.I got some video editing practice. Digg the 97s (CZ FuddRunner) – it was a great day! The trigger action and shape of the older one has the slight nod, but the newer model has better sights and LOK grips(upgrade). […]

    We all have things to work on… I try to be the person to at least think those words when disposition comes along. I’m starting to feel really great about breaking bad habits. In particular for today is You Tube… So I started up Rumble and what do you know one of the first things […]

    I had a couple of recent range trips with some ridiculously long 22 pistols. A couple of weeks ago I shot the Ruger Scoped Black Grand Mamaba out to 200yds. This past weekend we piled up a mess of other Rugers as well and shot them at the 50yd berm. Targets were a mix of […]

  • First PRS match at Alabama Precision

    Well, that was humbling… many reasons to underperform and so I did that quite well. The biggest weakness that could have been avoided was practice on barricades and moving positions, so I will be working on that for sure. This pic sums it up basically. The guys at AP were top notch and the facility […]

  • SAR K2-45 Grip Size vs CZ 97

    by on 2022-05-12 - 0 Comments

    In terms of “Feel” SAR wins. It is a more rounded grip and feels more natural, like a monkey paw grabbing a tree branch. The CZ97 is more of a flatter grip. The grips are wider, not thicker per sey. So there is more distance from the webbing of your thumb to the Slide Release […]
