I found this at http://www.firequest.com for $39.99. They claim it fits Ruger Mini 14 and Colt AR 15. Anyone have experience with one of these?
Fits both Colt AR-15 and Ruger Mini-14®
• Tough Aerospace Polymer Plastic Can’t Rust or Dent!
• Full Factory Proof and Field Tested!• Fully Guaranteed to function
This remarkable magazine fits both your AR-15 and your Ruger Mini-14® rifles and with its smoke colored semi-clear form it looks good too! This is a great product with an even greater price!
Your link just goes to the home page, but I assume that you are talking about the RamLine combo mags. I have several of these and they work pretty well in my Minis, but the mag well on my bushmaster is too tight to get them in easily. They function well, but I don't know how the plastic would hold up to hard use. YMMV.
I also had good luck with the Ram line in the mini14. I tried another brand that did not work as well, misfeed about once every other mag. If I remember right it was Eagle brand. It did hold 35 rounds. This was a while back; before magazines with more than 10 rounds would destroy your soul.
