Summary

I wanted a modest mag extension for my el-cheapo shotgun. The requirements were
a. one piece
b. black
c. factory threads
d. cheap
e. cheap

Since this didn't exist, I threw this together. there's some stuff out there that's like $70 for a +1... ridiculous. seeing this nonsense, i just made this in 10 minutes. there's a hole to swap the sling swivel jawn into as well.
there's also a curved picatinny mount that fits the profile of the tube extension that can be mounted to it. i was going to use this for a flashlight but decided this was a little too bulky. great for someone who likes the whole ar15 hang-a-coffee-maker-off-the-side-of-my-rifle lifestyle.
otherwise, in the future I'm going to try making a front grip / pump that has a streamlight built into it.
I removed the factory magazine tube cap nut thing and just screwed this on. I may have stretched the spring out a little but idk it feeds and works fine.
enjoy, be safe.

i printed the rail upside down / curve up with supports.
