    Great springs

    Used the springs to upgrade an extended mag with worn springs and they worked great stiffer than factory but not to stiff to impede use of the mags.

    Quality product, excellent support!

    Arrived with good packaging. First, the springs appear to be of very high quality and excellent finish. Was unsure of how to install it properly. Called Taran Tactical spoke with two people, both very nice. I was walked through the installation of the magazine springs. He was very helpful and informative. I can't be happier with the way I was treated. You know sometimes you call a company and ask a question and made to feel like an idiot. Not here "apparently the customer is important"! Thank you to both of you, your company now has a loyal customer.

    OEM mags have weak springs. These replacement are great!
