SXP & Briley mag. extension

[Simonsez]

This turned out well- a +2 extension under a 24" bbl. Removed dimples in magazine tube with drill bit and polished interior with a stone drill. Added a Nordic mag. tube follower and works as good as OEM. Feeds anything and should also take +2 3" shotshells.
Realized after purchase that Nordic now also has them for Win. SXP and 1300 series for about the same cost...
