The Kaw Valley Precision AR-15 Anti-Walk Pin Kit Set, .154” (Kaw Valley Precision part no. KVPAWPIN154) replaces standard hammer and trigger pins with a set designed to prevent the common problem of pins slowly walking out of the lower receiver under recoil. Anti-walk pins use a stepped or captured design on one side of the lower to keep the pin from migrating, a particularly useful upgrade for shooters running an AR15 without a right-side pin cover plate. At .154 inches in diameter, this set matches the standard AR15 hammer and trigger pin size used across nearly all mil-spec lowers and drop-in trigger groups. It’s a simple, inexpensive reliability upgrade that takes only a punch set to install.
