RDSWriter 5 Posted November 29, 2007 Report Share Posted November 29, 2007 (edited) Over the past few years, I've read a number of posts regarding the reliablility of different modifications to the gas ports, barrels and springs. In short, I will be cutting my barrel down to 13". From what I've read, this should be long enough to leave the gas block in the original location by opening up the gas ports and or adding and fourth (and potentially fifth) port if necessary. What I would like to get from you RKIs is: 1. Information from anyone currently running a 13" barrel - your mods and tips. 2. A link to the C&S Metall Werkes modification to the gas system for a 12.5" barrel. (I've looked for over and hour and can't find this older thread.) 3. External web links that may elaborate on ensuring reliability without moving the gas block. Thanks Edited November 29, 2007 by RDSWriter Quote Link to post Share on other sites
