Just to clarify a couple of points.
Remington came out with the Flexi-tab system in 1983. It consists of modification to 3 parts; the U shaped cut in the carrier, two cuts on the back end of the slide (the part that fits under the breech bolt) and a cut on the bottom of the breech bolt at the front.
This system was put in place to make it possible to clear a problem where a shell gets between the carrier and the slide. With the flexi-tab system, the operator pumps the gun in a normal fashion, albeit with a LITTLE more force than necessary.
Prior to this system; if the same thing occurred, it could not be pumped.
All 870s leaving Remington since 1983 have all three parts of the flexi tab system. If your gun is a 2006, the carrier has been changed with a pre 1983 carrier or it is not a Remington carrier!

But my 870 is made in 2006...why doesn't it have the "U" on it? It's an 18" express 7-shot
