re: If you are afraid to buy a polymer lower for your AR........

I have transferred about 30 of the new frontier lowers. Don't be scared of them because they are polymer. I have one customer that has over 10000 rounds thru a plum crazy lower and no issues.a few other have over 2500 thru them. The pics that people are posting of the of the broken receivers you dont know what was done to them to crack it like that. I dont know what they did to apply that much force to tighten or loosen the castle nut. I have sold around 100 plumcrazy and new frontier lowers and only had 2 issues. a sear cracked (never did see it to see if they tried to lighten the trigger) and a rear take down pin cracked. These were both with the Plum crazy receivers. If you are looking for a cheap lower these are it.
