I have acquired all the parts for an AR15 build and today I got started. I put the lower together with only a few minor misadventures.
The upper receiver was a bit harder and I hope I didn't break anything. I installed the barrel and then test fitted with the gas block, gas tube, bolt carrier and charging handle. Unfortunately, the bolt carrier bound up and I had to take the barrel off in attempting to get it out.
Here are my two questions:
1. Did accidentally over tightening the barrel nut but about 1/4 turn do any damage?
2. What is causing the bolt and BCG to bind?
