Noveske AR-15 Takedown and Pivot Pin Sets are a great way to customize your AR-15. The crisp Noveske "Iron Cross" logo will dress up any AR. Machined into the head of the pins, the subdued logo will never wear off and makes a statement without distracting from the function of the firearm. The 0.250" pins are designed to work with any mil-spec upper and lower combination. The nitride finish and 4140 hardened steel construction ensure these pins will remain functional through years of hard use and all operating conditions.
