Ya it sucks about them lips on the 10/22, I've gone thought a few mags in a short amount of time. Out of 4 mags, only one works perfect (butler creek mags), the rest, the first 2 or 3 rounds might jam up but the last 4 or 5 rounds will not feed into the gun at all.
To bad them lips cannot be replaced. To bad we cannot get mags from Canada!

I found a web page and they are selling NIB 25 round butler creek mags for 34 bucks! But look were they are located at. http://www.rugermags.com/

I have not even see the factory Mini-14 mags (20+) for sale in a long time. Sure wish I could fine some.
But like I said before. All the aftermarket mags for the Ruger Mini-14, I have yet to find a good 30+round mag that feeds good all the time.
I picked up some very cheap mags, you could tell they were cheap just by the way they felt. I got 20 and 30 round mags for 15 and 18 dollars each. The 20 rd mags worked just fine but the 30 round mags I ended up trading off.
