I have over 800rds through a PET-CF Defiance lower receiver, with brass inserts for the trigger assembly. They are 100% a viable option, and I've had 0 issues with cracking or breaking of the original I printed. I just wanted a one-piece design. The only part of the lower that gets worked and is prone to breaking is the buffer tube mount. There's 0 "pressure" in an AR lower, to worry about "tensile strength" in that regard.
