    SIG Sauer has a limited number of complete SIG551-A1 lowers, including stock and magazine, which can be used to convert a SIG556 to a SIG551-A1.

    Only 250 kits are available and they are only taking phone orders. Call (866) 619-1128 or (603) 418-8102.

    I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!
