Got my feet wet putting together an AR lower for the first time, great fun with my son. Found some great instruction videos on youtube and got ALMOST everything together. Big question, the upper (already built kit from PSA) and lower won't go together. The lower is an Anderson Mfg receiver bought locally and a PSA parts kit. I can snap in either the front pivot pin or the back pivot pin but not both when trying to join the upper and lower. With the front pivot pin snapped in and feeling in the rear pin holes with a toothpick I can feel that the three holes are not fully lined up, there is a ridge from the upper sticking up slightly out of alignment.
I put the completed upper on a different lower from my current rifle and it fit fine. The upper from my current rifle fit fine on the newly built lower. What gives and how do I get this fixed?
I have basic hand tools but no gunsmith tools or machining tools or experience. I am fairly competent with tools and building but certainly not trained or a craftsman. I am not afraid or to proud to get help. I Live in Lebanon, IN so looking for easy suggestions to fix on my own or recommendations of where to take the gun for fitting. This is a budget starter gun for my son to shoot and participate in shooting sports with, high dollar improvements and customization are not in the cards. Thanks in advance for your help.
Yes, you can make fun of me, I can take it.
