Directions are poor but a bit of playing around and it installed perfectly.

It’s a 3 position stock
1. Fully extended
2. Mid extension
3. Fully collapsed

To install make sure the nut in the pistol grip is properly seated in the nut cutout of the pistol grip.
Do Not install the stock yet!
Remove the trigger housing on the shotgun
Remove the factory stock
Make sure you properly align the threads of the pistol grip nut to the male threads on the shotgun.
Slowly turn the entire pistol grip until it is tight and is aligned vertically. Reinstall the trigger housing (this keeps the pistol grip from backing out no need to over tighten the grip)
If the grip is not tight back off a few threads and try again mine took twice. Also make sure the nut didn’t come out of the nut cutout of the pistol grip or the timing of the grip will be off.
Hold the button on the stock and slide over the tube turn back and forth 45 degrees until it slides on.
Once it clicks and is on (it won’t come off the tube even with the button pushed in)
Push button and twist stock to adjust (lines on tube indicate adjustment placement.
