If you can deal with misfeeds this may work for you. - Pro Mag Ruger Mini-14 .223 Rifle Magazine

I previously ordered 8 10 round magazines for my new Ruger Mini-14 as the factory magazines are nearly twice the cost. At first all seemed to work o.k. with a few misfeeds at the beginning of one or two magazines per my earlier review. So I gave this product a 4 star review with the proviso that I thought the issue would resolve itself. Such is not the case however. Subsequent use indicates that there are some serious issues with how these magazines work. My latest experience was one in which I used all 8 fully loaded magazines, and during that time I had multiple random misfeeds. I was only able to resolve the issue by pulling and reinserting the magazine before it would strip a round into the chamber. As a matter of fact I got a "click" in stead of a "bang" twice from the same magazine! If I were to rely on these magazines in a self defense scenario I fear I'd be in serious trouble. Even my local gun smith (a Mini-14 guru) tried to fiddle with his Pro Mag magazines, and he gave up and got Ruger originals. I may keep the mags (for practice at the range) or destroy them, as I can not in good conscience sell them. Meanwhile, I will bite the bullet and get Ruger factory original magazines.
