    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.

    These are amazing mags. I was a little skeptical at first then I just said screw it, buy one. I ended up coming back and buying 3 more. The quality is great and they look really cool. I have had no issues with feeding or anything. I will buy again and again :)

    Good mags

    Very happy with the purchase. They are very light weight and work flawlessly. Lighter than magpul magazines. Very easy to swap springs to be legal in different states.
