Yeager Posted November 30, 2006 Report Share Posted November 30, 2006 Hi, Searched, Couldn't find jack on the OA 93 Kit. So I'm posting here.. Question: How is the outer barrel threadded? I've tried putting my marui M4 birdcage on it and it just wont go on. So that atleast rules out 14mm- as the threadding type. Link to post Share on other sites
