Just to be clear I am not bashing polymer 80, I have not yet reached out to customer service about this but I need to vent. I have gotten two frames from them so far and both have not worked out! Wont lie im a little heated!!! The first one I can say I might have messed up the back hole pin alignment but even still the front frame and back frame wont seat properly there a tiny amount of metal stopping the pins from going through!!! The second one I took my time on I used a level on the jig while it was in the vice used the drill on slow and had someone second check that I was lined up straight and even with the drill both pins fit perfectly across, but when the rails are seated they have a tiny bit of metal in the way from pushing the pins through on both the front and back rail x2 on both frames!!! What are the chances someone gets a lemon twice am I just an idiot I know how to use a drill! I have seen there has been issues in the past with this but twice!!! Is it just me? Im going to contact customer service tomorrow and see what can be done but dang is it depressing.
