Nordic Components - extended magazine tubes for Winchester SX2 and SX3 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 and +5 configurations for the Winchester SX2 and SX3 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.
Overall length of the tube extensions (including the nut):
+3 - 8 1/4 inches
+4 - 10 inches
+5 - 11 5/8 inches
Using the tube overall length provided above, please determine the complete installed length of your shotguns fixed tube and the tube extension. Once this is done, it should be apparent that some tubes will extend past the end of your barrel when installed. 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.
An extended spring is included with the magazine extension tube.
Followers, clamp, clamp rail and speed bolt handle in the image below are for display purposes only and are not included with the magazine extension. These items can be purchased separately.
