Great add on - TANDEMKROSS GearBox Replacement Sear Spring

If you follow the online video, it's pretty easy to install. I was hoping for a little less trigger pull. I have only shot 10 rounds, but so far, I am pleasantly surprised at the difference in trigger pull. It's a little on the pricey side, but it's worth it, in my opinion. I'm not a fan of the flat face trigger, so I am sticking with the factory one.
