Have the tolerances of your lower opened up to unusable &/or sloppy levels?
I ask because as I understand it, the reanodizing process permanently erodes aprox. 1/1000 of an inch of the base Aluminum as part of the process.
Is your reanodized lower loose now? Do all the pins (trigger, pivot, etc...) still fit tightly? Do you detect anymore play between receiver halves than before you had it reanodized?
Thanks.
