After a thorough beta testing, the CSGCS is finally released!
Rated for around a thousand of rounds of use (depending on your setup and application of course - abusive blowback actions will kill it quicker than an AR15 in 22lr will), it's above the bar of being a shoddy stopgap (but obviously not going to be superior to an OEM setup).
Costing right around a dollar to print and as little as 8 bucks to assemble (if you buy springs from China), it's a cheap, reliable (within the limits of it's service life), and all around "good enough" option for your build. Gain the bragging rights of making your own fire control group, make a hilariously lightweight lower build for your AR15 22lr blaster, and avoid those situations where you can't find fire control groups in stock.
For those that wonder - it's a single stage trigger pull, around 7 pounds. Reset is punchy and tangible.
