T/C R22 Spring Kit

Big improvement from the factory springs, watching UTube 10-22 videos are helpful but the lack of detailed instructions make this a somewhat difficult task. End result is worthwhile.


T/CR22 Trigger Spring

Have been aware of MCARBO via YouTube. First purchase from MCARBO. Has been great experience parts arrived quickly with timely updates. Which i consider as part of my review. I ordered the T/CR22 Trigger spring kit,. With the new spring coming in a packed zip lock bag, which is appreciated as I can store original springs in zip lock bag.. very well though out packaging for customer. Installation was a breeze. Trigger pull before up grade 4.75 lbs. Trigger pull after upgrade consistently 2lbs. Fantastic 5 star experience from ordering, shipping, packaging, installation and outcome. Easy 5 star rating

Big Difference

I picked up a performance center TCr22 that had a horrible trigger, I decided to try the M-carbo spring kit before I sent it in for a $120 trigger job and to say the least I'm glad I did, I installed the kit and polished and lubed the trigger return spring plunger, I went from a creepy off my scale garbage trigger to one breaking cleanly at 2.5 lbs. after a very smooth take up.
I haven't shot it yet in a NRL-22 match but I think its going to perform well.


Good kit, horrible trigger

My only complaint from M-Carbo is not having a video of the installation. It is a bit tricky. As others did, I polished surfaces while I had the trigger apart. Ended up with a lighter pull but still a LOT of creep. Thompson should be ashamed to have such a sorry trigger in a very nice rifle.


Great upgrade!

Took the factory trigger pull from 4#12oz down to 2#11oz. Easy install.
