So on this note... I just picked this poor little abused guy up. Its a wingmaster someone sawed off the barrel. Came through the store. I had to throw the barrel away. ( to short ) so is just the Remmington mag extension acceptable. ? and yes ... its days as a duck gun are probably over. I have another wingmaster that the wood from this one will go on.
I have a Wilson +2 on my 870 and it is very sturdy, but also adds weight at the very end of the gun. I haven't used any other extensions, but the Wilson is very durable.
Vang Comp +2 extension with sling attachment, just because Hans is a good dude and has worked on 870's before Wilson ever bought Scattergun Technologies...
Thanks for the positive review of the Wilson extension. I've been thinking about the OEM extension and could not find one in stock and the price was a little high. I expect Wilson's extension will be just fine
