Here in Pennsylvania, humidity is always an issue. No worries, Bud's carries High Capacity Magazines resistant to corrosion. From my fingertips to my door in days. I shop Bud's online because i know I'm receiving top quality merchandise at rock bottom pricing. Remember, an unloaded gun is called a club !

I have enjoyed my new 42 round magazines, easy to load and use. Makes my AR-15 look even cooler. It is of great peace of mind to know I have more bullets than any home intruder and I can protect my family. Love Bud's customer service and speedy delivery. Highly recommend the K2 for home defense and personal use. It is a lot of fun at the range and a manageable recoil.

I had no problems with this magazine. It loaded easily and quickly and worked flawlessly in my AR-15. The additional 12 rounds is a great plus!
