  1. There are a few common issues with the CMMG RDB that could be causing your issues of extraction/ejection. Your extractor spring is weak - I only run extra power extractor springs (I change them annually or every 5k, whichever comes first), they are one coil longer and you don't need all the hokie o-rings to make them work. Your extractor may be damaged or full or carbon. When you clean your bolt take a metal pick to the extractor to assure there is no carbon build up on the hook. You ejector spring is weak or dirty. If you have never pulled the ejector it is likely full of
  2. I will bet JP doesn't require 3 generations to get it reliable. There is a high probability they will hit the mark out of the gate and it will be well supported.
  3. Delayed roller would be an awesome upgrade in a PCC with AR ergonomics, hopefully they put it on a diet as well.
  4. I use dry lube spray. Spray it into a plastic coffee can then drop brass inside and hand tumble it. It dries on the brass and if it does get inside the case it will not cause powder to stick. Once loaded you can wiped off with a rag or dry tumbled off. A can will go a long way and is more economical than one shot.
  5. There is a big difference between brake fluid and break cleaner. Non-chlorinated brake cleaner is safe on hard plastics.
  6. You spray brake cleaner down the primer magazine? What frequency do you spray it out? I assume you are using non-chlorinated brake cleaner to prevent any corrosion?
  7. I don't think this got answered but the factory guard ejection port opening is about 0.62 in. I don't really see a need to open up the port if the extractor and ejector are working correctly.
  8. Anyone trying to install the extra power extractor spring make sure you aren't trying to use the original plug or an o-ring. With the larger diameter end of the spring down on the bolt you should be able to lay the extractor on top of it then compress it in the middle and insert the pin.
  9. I am running on colt mags but I modified my mag slots. When I added the extra power extractor spring I don't need to use a plug or an o-ring.
  10. I had some extraction issues and solved it with an extra power extractor spring and removed the plug completely. Zero issues since then. Do you have some pics of your extractor where it looks like it is contacting the barrel extension?
  11. I have never seen a metalform mag (the only legitimate colt mags) need tuning.
  12. I have never heard of tuned colt smg mags, how are they tuned?
  13. $44 for an uncaptured guide rod and a replacement spring when you can just by a single spring and spend 10 seconds opening one end, no thanks.
  14. Think I read they weren't being released until late Dec.
  15. Just bottom out whatever primer you use, problem solved. I load everything with CCI SRP with zero issues, even with striker fired guns.
