Let's see... I had a 24 and liked it... the gun was all black and I traded it off for a full camo version. It has a 21 and it works well... but I find that I prefer the longer sight plane. Anyone have a new stlye MOB camo barrel for an 870 longer than 21 that they want to trade? This 21 inch is equipped with Remington's fully adustable Tru-glo style sights... factory model... not an add-on. Like 'em short? Drop me a line.
