Yep my friends all say the same--- perfect!!! But don't buy from botach--- I know they have a deal now-- buy from mako.com.
They are the equilivent of the ak47 all steel mags that will outlive you! Really. With mag ban last year-- these were the ones I was buying. Best part-- they will work in anything. Scar, fs2000,ar15/m4/m16.
at at the time of that post, I just didn't know about fs2000 usage.
I have been running one for almost a year now. Its okay, a bit heavy like the factory FN Scar mags. No more or less reliable then aluminum GI mags. They are fine, but wouldn't pay more then $10 each for them (which is the going rate for Mil-Spec mags with Magpul followers).
