I couldn't be happier with Sig Sauer. While I was trying to adjust the SB15 arm brace for my Rock River Arms LAR-15 pistol, I caused a couple tears in the rubber material. It was still operable and I don't believe they would've tore anymore, however they didn't look great. So I called them and Jay, their customer service rep asked me to email him some photos. I sent it to him and he immediately replied, send it to me and I'll send you a new one. - Thanks jay and thanks Sig Sauer!
