Sometime back I sent my PMR-30 to the Mother Ship for repairs. After over 1 month I finally received it with a list of repairs. One of those was a ( NEW ) front sight. Went out to try it out and the fifth rd. the front sight jumped completely off the barrel into the dirt and we never did find it. Waiting again for them to send me another ( hopefully better ) new sight. The one they replaced had 400 rds. through it and was deadly accurate. Noticed lots of threads about loose front sights. Any suggestions as I don't want to go high tech. as the original front sight was all I needed. Thanks
