Just completed my 9mm build and have a problem. After the build I started a function check…checking just like an AR(that is all I know) The prob is once I pull the trigger and the hammer falls, the weapon is locked into battery. When the hammer is cocked the bolt carrier moves just like it should. No matter how hard I pull the charging handle the bolt carrier will not move. I can disassemble the weapon and the hammer is easily cocked and the bolt carrier and charging handle move freely. I even removed the magwell block and still have the same problem. According to all picss in the forum and other places online I have the correct hammer installed.  I there something about the 9mm I don’t know? PLEASE HELP?????

Are you using a stock hammer or one for a 9mm kit?

9 mm hammer according to all the pics I have seen.  I looks exactly like the one on the Rock River web site.
