If someone has a bunch of triggers to do, and also has no interest in the supplementary sear springs that Skyler worked up, or in the replacement spring pin needed to install the MicroG in Chinese variants, then buying bags of screws, springs, and nuts and following my online installation instructions is a perfectly viable way to go.
And more power to him.
This, of course, is why I put the McMastersCarr part numbers right in the installation instructions.
But those who have just one or two triggers to do would probably be better off sending their $10(s) to Skyler:
