Our lower receiver parts kit comes with all the components necessary to complete a lower receiver build, including springs, disconnector, selector switch grip and more. While our complete LPK comes with the most affordable price on the market, it also comes with a hammer equipped with an anti-walk pin at no extra charge. We don't think you should have to worry about the hammer pin walking out over time. We custom designed our anti-walk pin to include two button head screws and two lock washers to tighten and lock the pin into place.
