There are at least a couple different versions. One is the much older version (which ironically, seems to be the only one available anywhere today) and the newer version which has been discontinued. The older one appears to be basically a Thermold design, cut down to 20 rounds (the similar Promag 30 round also looks rather like the Thermold). It is straight with no curve. From what I have read, these may work right off in your gun, or may not, and the problems are pretty much the same as the Thermold.... the bolt rubs on the top of the feed lips. Once these are filed down a little or simply worn in, everybody seems happy with them (many others though hate them and have no desire to break them in). I do not have any of these, but am considering getting a few. I REALLY just prefer 20 round magazines for my Mini 14. Although I HATE dealing with Cheaper Than Dirt, they have them for sale for $11.97. I may have to just bite the bullet and get some.Promag 20 rd poly mags
Anyone have experience with these mags? The poly ones?
Mag body - $7.99: Ruger Mag Body 5-Round Ruger Mini-30 Blue
Follower - $2.99: Ruger Mag Follower Ruger Mini-30 All Models
Spring - $2.99: Ruger Mag Spring Ruger Mini-14 Mini-30 5-Round
Base plate - $2.99: Ruger Mag Bottom Ruger Mini-30 All Models
That's a pretty good deal. Odd that they're selling the full mag assembled for $24.99
it's a shame that we can't get no tilt magazine followers the way AR owners can. I bought a number of lousy aftermarket magazines that would work if I put good followers in them otherwise they are not that usable.
Just ordered six 10-round OE mags for my Mini in anticipation of Virginia going full-commie.+1 : I bought Ruger factory followers - cheap - and dropped into some aftermarket mags which didn't lock the bolt back. Worked fine with the factory followers.
