    Everything is great except the length, if you made it the same length as the standard 20 round original size it would be easier to fire from the prone position.

    For Colorado, and the 15 round limit, these are perfect. Good solid construction, already loaded and in the kit.

    I bought this, honestly because of the color options. Secondly the price was cheaper than most other options. Lastly, the shipping was great, and the product works well with my weapon and ammo.
