The rimfire experts over at Tandemkross have a new trigger for your Ruger 10/22. They released the “Ultimate” trigger kit on 10/22 of 2018 in collaboration with Brimstone Gunsmithing. I immediately contacted them to ask for a review trigger kit, well here we are with the trigger review! I was sent a red trigger, but black is also available.
As mentioned, this trigger system comes in a “kit.” Of course there is the trigger. The trigger is made out of aluminum and anodized either red or black. It uses a wide flat faced design, with very sharp knurling on the face of the trigger. I loved the knurling. My finger immediately knew that I was on the trigger. Now I would maybe put a small chamfer, or angle, on each side of the trigger face. It felt a little sharp on the edges. There is also a over travel adjustment in the trigger shoe. The adjustment is just your standard set screw that butts up against the back of the trigger guard housing. A hex wrench is supplied for adjustment.
Tandemkross’ Ultimate trigger also comes with a new hammer and sear. This is really what makes the trigger pull lighter. Tandemkross redesigned the sear and hammer. This leads to a reduction in pull weight and a boost in reliability. The reliability is increased, due to the fact that the hammer-sear still have strong engagement. It doesn’t say if the surfaces are polished, but it does mention they are EDM cut for precision. Either way, the trigger pull is fantastic.
Last up in the Ultimate trigger kit, is the return spring. Why should you care, you ask? Well Tandemkross has ditched the spring and plunger system used on the stock Ruger 10/22. They have gone with a wire spring. This spring mounts to the side of the trigger shoe and rests on a shelf in the trigger housing. I found it gives a positive reset without adding anything to the trigger pull.
I’m not going into installation. Tandemkross has some very good instructions. If you don’t think you can install the trigger, take it to your local gunsmith. I did have a small problem with the hammer, the hole was too small for one of my rifles hammer pin. Another of my 10/22’s hammer pin fit fine. I chalked this up to the one not fitting, having been built in the early 80’s.
I am really impressed with the Ultimate trigger kit. It reduced my trigger pull from the factory 5 lb pull to an amazing 2 lb pull. Just by installing the kit and using factory springs. There is a tiny bit of pre-travel, but not even close to the factory trigger. I’d say the pull was smooth, but the travel is so short that it just breaks without being able to feel any creep. As mentioned, getting rid of that spring and plunger system is great also. It now looks like a trigger should. Having over-travel adjustment is nice also. The set screw supplied also has a rubberized tip to keep from marring the trigger housing. I also love the feel of the sharp textured WIDE trigger.
Tandemkross did an excellent job, in my opinion, with this trigger kit. If you know anything about them, that probably doesn’t surprise you. At $145 for the Ultimate 10/22 trigger kit in red, it might be pricey for some. After using it, I feel it is worth the price. If you’re in the market for rimfire parts and accessories, do yourself a favor and go check out Tandemkross.

Essential Trigger! 5/5 stars on Tandemkross
Installs in minutes with YouTube help. And makes a scary big difference. 10/22 factory triggers are like Glock triggers. We usually just compare them with something worse. But this TK Ultimate Trigger is a whole different world of goodness. Silky smooth take-up right up until the glass-rod break. Even upgrades Ruger's own BX trigger upgrade. Mine breaks clean and reliably at about 3.2 pounds. And since the heavily textured flat shoe provides oversized purchase onto the pad of your trigger finger, the effect is even more dramatic. Dry firing with the Ultimate Trigger is impressive, but when out in the field whether poking targets or hunting small game, the TandemKross Ultimate Trigger immediately makes itself essential. I've upgraded a lot of 10/22s and I cannot name a better single upgrade than this trigger for better performance, increased accuracy, and most importantly just the sheer pleasure of shooting.
