Several retailers have started offering a Direct Impingement Conversion Kit (DICK). This kit replaces a number of moving parts and springs which may be found on piston “conversion” AR-15s. In addition, the DICK corrects geometry issues and reduces heat at the gas block, which can lead to premature erosion of various components. The DICK takes only minutes to install and also reduces felt recoil. And best of all, the basic DICK starts at only $9.50! Get yours today!
