  1. hi amphibian – if someone drilled two more 5.56 ejector holes – one on either side of the center ejector of a CMMG radial delayed bolt (mimicking the pattern of AR10 style dual ejectors) – do you think that will help reduce the impact strain on the ejector springs and increase their lifespan, since the force is distributed by 3 ejectors instead of one?

  2. Is that actual extraction or is that just inertia from the recoil and back pressure from gas expansion?

    Thanks for all the research you have done! I pick my CMMG upper up tomorrow and I have been looking at your work and attempting to figure out how to get a Tubb Flat Flat Wire Buffer spring and Kynshot RB5004 to work in the CMMG Micro RIPBRACE… but only after I verify the operation of the original equipment first.
