I just traded a rifle yesterday (a well used and abused Remington 760 chambered in .30-06) for a gently used Remington 870 Express Magnum chambered in 12 gauge. It has something like a black, rough to the touch, kinda like spray-on truck bedliner finish. Is that what I here called Parkerized? It also has black, synthetic stock and forend, which is the standard length. It also has what I think is a 18.5 inch barrel, but I need to measure it, with bead sight. It has no tube extension, and the hunting plug or whatever is still in it so that it only holds 2+1. They were asking 300 for it. One of the first things I'm going to do is remove that plug and also get a +2 extension. To just remove the plug, do I need a different mag tube spring? And do the extentions come with a new spring as well? I then want to get the shorter, "Tactical" forend, but I'm unsure which one to get. I was planning on just getting a black one but after seeing some of the tactical shotguns on here and how nice they look with wood furnature, I'm starting to reconsider. Only thing is that I might later on what to get a pistol grip, collapsable stock, and I really like the sounds of the one with the buffer tube that I believe Mesa makes. Actually a Tan or Green stock might look nice too. One last mod that I want to do for now is some type of simple sling.
