The TANDEMKROSS “ULTIMATE” trigger is an awesome upgrade for competition and recreational 10/22 shooters.

I recently received the NEW “Ultimate” 10/22 trigger from Tankemkross. After taking trying out the trigger at multiple competitions and some decent range time, I’m sold.

The bottom-line is YES. There is not many fire-arm components where I’ve immediately experienced a VERY noticeable impact to my competition time/score.

The “Ultimate Trigger” has accomplished that, most likely by reducing trigger pull to under 2 lbs, shortening the over-travel, and a crisp reset.

Below is a comparison of October to November USPSA Steel Challenge this year. October was pretty much a standard match for me, using the factory 10/22 trigger, I attribute a good portion of the 8.5 seconds faster in November to the TK Ultimate trigger. The other portion could just be me having a better day. It may not sound like much, but 8.5 seconds in Steel Challenge is a pretty massive drop.

Additionally, here’s a video from the most recent Steel Challenge match testing out the TK Ultimate Trigger. I apologize for not capturing a better view of the trigger, fairly difficult from a GOPRO.

I’m a big fan of the “Ultimate” trigger design which is flat-faced, great texture, and adjustable over-travel.

The design is heavily tested via TK’s “Victory” versions for rim-fire pistols & Ruger PC Carbine.


Installation is not difficult at all, I believe any level of gun-owner can accomplish this task. Tandemkross makes some of the best install/how-to videos I’ve seen.

Switching the trigger out for the “Ultimate” took me about 10 minutes. Most of that time is me just dropping things.

The provided parts included a hammer, sear, trigger shoe, wire spring, nylon-tipped post-travel screw, allen wrench, and slave pin.


The “Ultimate” works with standard and BX(+$10) trigger housings, but you need to specify when ordering so… if attempting to install in a BX trigger housing, you will not be able to use the BX disconnector.

The trigger is available in black or red (red is +$10), the finishes TK produces are top quality.

This trigger does not come with an extended magazine release but TK produces a great one called the “Fireswitch”.

Currently the Ultimate Trigger sell’s on for $134.99, but TK is know to have some awesome sales during various holidays.


There are A LOT of 10/22 trigger groups on the market (BX, KIDD,TIMNEY, VOLQUARTSEN, Clark Custom…)

BUT, the Tandemkross “Ultimate” trigger is unique because it’s a drop-in replacement trigger, without paying to replace your current trigger housing.

It works great! With a crisp sub 2lb trigger pull, easy install, and reasonable price, I would say it’s a solid buy!

TK did an awesome job on the quality in machining these parts and I can’t wait to see what they come out with next! Keep up the great work!

Good shootin!
