For all that were following this thread, it took IGB Austria nearly 18 months to finally replace TWO poorly designed barrels for my Steyr. Many phone conversations and emails with Carmen went unresolved. Recently, Carmen became unavailable, and I have not been given a direct answer as to why. Carmen was always delightful to deal with. I know she had some medical problems, and while I hope all is well, I fear it is not. In Carmens absence, Viktor did begin correspondence via email, and finally made good on his products. I wish the very best to IGB.
