I also agree that Laib's is the place to send your 3200. I recently sent mine in for a repair and I also had them do the forearm update and they did a great job for a very fair price. They also go over the entire gun and inform you of any recomemded replacement parts. When I got mine back it was like new. Pat Laib is a great guy and so are all of his employees.
I sent my (new to me) 3200 to Laib's Gunsmithing last spring. Inspected, cleaned, lubed and replaced worn parts. Like new when I got it back. Great service and price. Would recommend them to anyone. They do have a website. It doesn't look right but it gets you there.
