Not the first time this has happened with a Ruger. Two months ago a man brought in a Ruger AR556 to my local gun store. He had just purchased it on sale at Cabelas. When he fired it, the front sight moved forward. Yep, you guessed it, no front sight roll pins. When he called Cabelas he was told to contact Ruger for warranty repair. Needless to say, he was a little hot under the collar when he came in. But 5 minutes later he was out the door, a happy camper.
Someone needs to tell Ruger to get their act together. Unfortunately, most repairs are being done in house so there is no feed back to Ruger.
