I bought to extra mags for my Model 14 and have had minor issues with one but I find that if I cycle the action in a more deliberate manner and ensure I pull the bolt all the way back, it feeds okay. These mags do have to be installed precisely, too. Make sure you don't go too far with bending the metal - slow and a little at a time then check cycling. My main objection was the price of these things. $48 per - that's ridiculous.
