Nordic Components - extended magazine tubes for Benelli shotguns
These are the finest machined shotshell tube extensions currently available. Each tube has a unique swirl style barrel nut (image on left) adding a distinctive touch while also providing a quick and sure grip.
Currently available in +3, +4, +5, +6, +7, +8 and +9 configurations for the Benelli M1, M2, SBE and SBE2 shotguns. Shell capacity is defined by Nordic as the shell increase above the standard capacity provided by the fixed magazine tube (tube inside the forearm). If your shotgun currently has a short tube extension that extends past the fixed magazine tube, the round capacity of that extension would be lost as it is removed and replaced. Magazine tube length is the length of the tube and nut.
The chart below lists some important information about the Nordic Components tube extensions. The most important measurement is the "Overall Length Installed" . This gives the installed overall length of the tube and fixed tube assembly. If you have an 18 inch barrel, you probably would not select a +5 or greater tube extension, as the extension would stick out quite a bit further than the end of your barrel. With the Recommended Barrel Length options in relation to your barrel length, it should be apparent that some tubes will extend past the end of your barrel. That is a perfectly viable option for shotgun use, it is your personal choice as to whether tube extends past the barrel. Please decide before you buy as to whether it is acceptable to you for a tube to extend past the barrel.
