Lowers are lowers and the more expensive they are the more they cost! We have found no real difference between them. I have seen crazy accurate match guns built on polymer lowers. What really matters considering receivers in the trigger system you use and quality of parts you put on them.
For our standard training guns, we do not want a really light trigger as my fat *** is running around, dropping down, kneeling and lord forbid squatting with the guns. A light trigger is dangerous so I just do a trigger job on a standard two stage trigger. For my DDV4 I did a Timney drop in.
We sell spikes and the surplus gun and ammo receivers more than any other kind and never had any come back for any reason. If you are buying second hand, stay away from AR57 receivers as some of the first ones they made during the insanity had miss aligned holes for the push pins. We bought a bunch of them and a lot of pissed customers but AR57 stepped up and replaced all of them and even paid for shipping. The customers could just send them straight in and get a replacement. I still have a few with misaligned holes and may sell them off as project guns stupid cheap.
