Alright guys. Probably stupid but here goes. I love my RCM bolt carrier and head. I've had no issues whatsoever in over 1000 rounds. Quality chit mang. One small nagging problem. I HATE how there is no retention ring for the recoil guide rod. Is there a reason this was omitted? Do the new ones come with one? I bought this one over a year ago. It's driven me nuts. Is there a way to retrofit the retention ring? I know it's petty but it does drive me insane. Otherwise a perfect product at an excellent price. I'd like to buy one for the upcoming K build but may pass if there is no retention ring. I know you can't please everyone but it seems a small thing here. Thanks guys.
