I ordered this stock looking for a more versatile part for my Masada, and for storage reasons. The stock is of very nice quality and is great. Cheek riser doesn't go up so high, but not that big of a deal. Also, one of the slots for the pins to go in isn't straight and curved the pin that holds the gun' supper receiver, probably mine only.
Folding stock- This is great for storage and if using a full face mask because the stock does get in the way.
Retractable- Allows you to change the stock to the length you find comfortable.
Small storage space for dummy bullet or tools
Held by spring tension
If you hold the gun from the stock, it won't hold and will go to the last position. This will also happen if you pull the stock from the end.
This happened to mine, but like I said above, the stock messes up the pin that holds my upper receiver. Probably a lemon.
