Maybe not. Do yourself a favor and take some fine automotive rubbing compound to the finish and you might be surprised what is hiding under that Remington satin (aka "mud") finish. The wood on the upper gun was refinished but the lower one was merely rubbed out.
Here are some of the photos of the upper gun the person I bought it from sent me. Even though they aren't the best shots, you can still tell that the change was dramatic! I bought that gun because of its low usage and great mechanical condition in spite of what looked like "average" wood figure at best. But even the person who refinished it was shocked at what was under that original finish.
My stock and forend are OK, but not what I've seen on some Comps. I bought the first one that came into the gun shop I worked for in 1982. The next 3 or 4 that arrived had increasingly nicer wood. Oh, well....
There might be another piston available soon. A poster notified me last night that he wants the extra barrel pictured above and plans to have it modified to fit an 870TC, so I'm guessing he will be selling the weight and related parts.
Let me know if you want it and I'll forward your contact info to him.
