Tandemkross 10/22 Ultimate trigger kit

 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.

HCMAGS HC3R 10/22 magazine

   HCMAGS is a company that makes an easy loading magazine for the 10/22, or any other firearm that uses 10/22 magazines. I first saw one of their magazine systems at a local gun shop. The idea looked really cool, so I purchased one. The magazine holds 25rds of .22lr with a side saddle that holds another 20rds for quick loading. 

  The HC3R magazine can be used like any other mag, but why? Well, since the HC mag has a slider on the side of the magazine, you could just slide it down while loading it up. But there's more. The back of the magazine acts like a stripper clip. One can push it down slightly and rock the whole stripper clip out. Fill the clip up with 25rds, pull the slider on the side of the mag down and lock it in place. Then roll the clip back into the magazine and release the slider and your ready to go. When the clip is off of the magazine, you can also put 20rds in the magazine side saddle before loading up the other 25rds. Once you have depleted the contents, you can take the stripper off of the magazine, slide it over the rims of the 20rds in the side saddle, and reinstall it with 20 new rounds. An extra stripper clip is included also. 

  Now I would have thought that this was the best thing since sliced bread. The biggest problem is that I couldn't get the magazine to feed in 3 different 10/22's. HCMAGS instructions say to watch their video on their website to make sure you are loading the magazine correctly. I watched it 3 or 4 times and still the magazine wouldn't work. I called them and they told me that I had a 1st generation HC3R mag and when the 2nd gen was out they would replace mine with a gen 2. They replaced it after about 6 months. Okay, sometimes manufacturing takes longer,  so I was alright with that. Now I have my gen 2 in hand, and it works a little bit better. It only jams about every 3rd round, instead of every time. I can't load 25 in the mag or it won't even feed, I have to load 20 to get it to feed the first round. Different manufacturers of .22lr don't seem to make a difference either. As is with different 10/22's.

  Basically the HC3R magazine is an innovative design. It is kind of a shame that it doesn't live up to its hype.

This magazine is difficult to load for me. I found bullets jamming during the loading process and falling out of the Rib Clip and extra holding channel when I didn't hold it properly. For me, it is more hassle than it's worth.

LEXRated at Cabelas 5/5 stars

Awesome and Innovative

There's not much real fun in loading, but this system these folks have developed is simply amazing.

Follow their instructions and get a couple extra magazines and this system will let you shoot all day and even for days. It is effortless.

NOTE: this listing is incorrectly listing the magazine as a 20 round magazine. Once they update the product to show it is in fact a 25 round magazine and it's part of the whole system whereby the strip clip feeders hold 20 rounds on the same mag. That means with one mag you have 45 rounds, 25 in and 20 out, and dumping the 20 in is super fast.

I hope Cabela's gets the HC Mags HC3R Tactical Kit (I have one already) but others need to know about it. I do not work for HC, just an impressed customer of their product and fan of Cabela's.

Additional note: some may say that having an open/exposed magazine makes it not worth it, but considering how much more one typically shoots with 22, i see the value in making the loading delays and effort go away and getting back to shooting more important. Plus, it's a breeze to clean and frankly, most of any significant debris easily going in, can fall out the same way. Mud is mud and play safe.
