    Solid lower at a really great price. I like that they aren’t flashy, just simple, tough, rugged lowers.

  2. CMack (verified owner)

    Good, mil-spec quality lower. I’ve handled a few of these over the last couple years. The tolerances on some are tighter than others in regards to upper fit, but everything seems to fall under “spec” where it matters.

    Amazing lower
