Someone please tell me im wrong :eek:
Does the mossberg 500 have a sealed mag tube which prevents it from excepting extended mag tubes ?

Thanks in advance ,

You're not wrong- Mossberg 500 magazine tubes are closed at the end except for a hole for the barrel retaining screw. This also precludes cleaning the magazine tube from the muzzle end- you have to remove it from the receiver to clean the tube or change the spring. IMHO that's the one major flaw with the 500 design, and was addressed by the changes Mossberg made in the 590.

thanks for that Lee :)
Ok ,Plan B :)

Am I right in saying that if I had a 870 and I wanted to put a mag tube in ,Id have to drill out some dimples .Is this Something I could do at home or is it a gunsmith job ?

Unless Remington has made some type of changes in the last year or so I don't know about, I don't think you have to do anything except put the longer mag tube spring in and screw on the extension........hpg

On the Remington, this depends on WHICH 870.

The Wingmaster and Police are set up to accept an extension with no modifications.

The Express models have some lugs (dimples) in the end of the magazine tube that hold a plastic magazine spring retainer/magazine cap retainer in place.

These dimples must be removed before an extension can be installed.

This is not a big job, and there are a number of removal methods from simply drilling the lugs out to "ironing" them out.

What about a Winchester model 1300???

Look at some well used 1300s vs 870s with the same mileage. The difference is there, trust me. The 870 is simply a more rugged gun, inside and out. Even the Mossberg is a better suited gun for social interaction purposes. When you see enough bent, dented barrels, stress cracked receivers, broken stock attachement points, and simply worn out guns, its fairly evident. Just to prove a point, the Oklahoma CLEET Police Academy does not allow the 1300/FN pump shotguns on the range.
