I'm a little hesitant to recommend another polymer magazine for the Mini-14, but it looks as though Thermold is finally producing again after a long drought. I will say this...I've tried them and they work very well. The lips are more substantial than those on the Tapco polymer mags, and the Thermolds I own have never let loose of a round, regardless of the weather conditions. Anyway, here is a link...can't beat the price...

Anyone buy any yet?

I have not purchased any of these new Thermold mags, but I own several that were made before they went out of production. If these new mags are the same, and I don't know why they would change, they are some of the best aftermarket mags available for the Mini-14.

I picked up a bunch from cdnn for my ar , they had them for 4.99 each. everyone was saying how bad they were when the canadians switched plastic formulas but they arent making them anymore, i have had nothing but good luck with them so id say go ahead on the mini.

Did they really switch formulas on the polymer (plastic)? How can we verify that?

its on the net thats why they didnt as good the canadians called them '' therm melts.
-------
The Canadian military licensed the Thermold design, but did not use Zytel as the polymer, using a less expensive plastic as a substitute.
This was not a wise decision, and the Canadian military had problems as a result. The most famous problem was the feed lips melting when their ARs were fired for extended periods on full auto (especially with blanks), leading the Canadians to dub the magazines "Thermelts". The other common problem was the mags splitting or cracking in cold temperatures or when dropped. After Desert Storm, the Canadian military changed to USGI aluminum mags, which are now standard issue.

'' as they would melt during a high rate of fire.

Too my best knowledge, the only melting mags were those used in full-auto weapons, which reach temperatures that semi-autos don't. I would guess that any of the polymer mags would fail in a full-auto rifle. I wouldn't be hesitant to go with the Thermolds in a Mini-14, a legal one anyway...
