I just purchased a Remington Turkey barrel for my son's youth 870. It has rifle sights and is 21" long. Yes, it's the same length as the factory barrel that came with it but I didn't like taking his sights off every dove and quail season. I saw a lot of conflicting descriptions of the barrel before I finally got a definitive answer as to what the barrel was like. His came with a Remington Turkey choke also.
Just wanted to pass this along. I saw the barrel mentioned nowhere in Turkey forums. The sights seem nice and are adjustable for windage and elevation. The Remington part number for this barrel is 80062.
Descriptions range from fixed modified and fixed IC to RemChoke. Some even described it as a rifled barrel.
Makes the 870 a bit more versatile.
