Some of you might be familiar w/ the issues I've had removing the stock sights from my Ruger 10/22 Carbine. After giving it one final try this past weekend I finally gave up & contacted Ruger. As expected, they have issued me a shipping label for return of the rifle. Now I have made several internal modifications to the rifle, inc. a new bolt stop, auto bolt release & a new extractor. My question is this: should I remove these parts & reinstall the factory parts before shipping the rifle back to Ruger? I am not concerned that Ruger will find them to be an issue, as these modifications function perfectly, & have absolutely nothing to do w/ the sights clinging to the barrel w/ the grip of grim death. However, should they replace the barrel & receiver, I will lose the aftermarket parts. That would suck, but so would having to tear up the rifle, removing & installing parts, only to do so yet again once the sight issue is resolved. Just sending the barrel is not an option, as the rifle is identified by the serial number stamped on the receiver. The entire unit must be sent. Any thoughts you all have would be much appreciated.
