I got the new parts installed in the 887. Did not take long at all. It took more time to cover the coffee table with cardboard / newspaper and get tools/ cleaning kit than it did to actually remove and replace the parts. I used the owners manual on-line so I would not get the finger prints on the paper manual that was included with the shotgun. I should have bought a Mossburg 500 or saved up a bit and got a Benelli Nova like I wanted. The M887 has a 3 year warranty, but hope I wont need to use it again. Jan 2009, my brand new 870 home defense failed to extract spent shell within the first 15 shells. Turns out the place I bought it from was not a Remington repair center. So I would either have to send to Remington, or drive to Erie PA to the closest repair center, if I wanted to use the warranty. Eventually it cleared up after about 100 shells through it. So, I keep a heavy screwdriver,hammer and a center punch in my range bag every time I bring the Remingtons to the range, just in case.
