RUMORED BUZZ ON REMINGTON 870 SALE

I want to find a barrel that may be for any wingmaster only? What duration can get me to original and they are there for a longer period barrels available? To who should I change Aside from ebay?I have seen a great deal of Standard 20s used in Skeet and no issues. The cracked 1100 I didn't get to look at had a hole drilled and was still trucking. C
