  1. With new BCG, the flat wire spring might have made it over sprung. As CMMG fiddles with headspace, cam angles, lock lug angles, the recoil impulse changes noticeably. So mine will arrive Monday I'll look it over and do a couple of mag dumps
  2. Here is what the repair label listed as work and partsUpdate mag well and mag catch window to current specReplaced BCG and updated mag catchComment flat wire recoil spring won't runstandard carbine spring and buffer installed runs fine
  3. I'm using CMMG bolt, barrel, lower, this is its second visit back to CMMG, and will be its third bolt. CMMG has been very good about taking the gun back, hopefully it is now fixed and will last well beyond a 1000 rounds. I've been through new extractors and new ejector springs also. Run factory Winchester or Federal 115gr We updated your mag well and mag catch as we have made some design updates to those areas since your lower was shipped out. The mag catch modification allows the mag to sit a little bit higher to allow for a .40 S&W upper group to utilize the same lower as the
  4. Lets us know if your still happy after you pass 1500 rounds, mine is making its second return to CMMG for FTE. Visit ar15.com pistol calibers to read about troubles
  5. You can close that gap, just put some marker on the wood or frame then assemble shoot, remove look for contact spots, then scrap those spots repeat until seam closes, I moved mine around some. The grip is smaller, as adding wood would be bigger project, I would like to make them longer into a big butt. The flare at the bottom was removed, because it was too high, it is supposed to be below your pinky, not under it. I could glue a contrast color piece of cocabola to the bottom but fitting the two halves and shaping the butt is a lot more work. Maybe if I start winning matc
  6. Here is the reply today from CMMG We have changed the ejector and extractor springs in those. We are currently waiting a shipment of the extractor springs. As soon as we get those in, I can send you replacements. Joe Dodson.

  7. I'm not running full auto and the two other shooters I know are not either. I disagree on extractor making it over the rim, bolt would not lock. I'm running the biggest spring and plug I can get in my extractor and after playing with moving the extractor further in made things worse. I took the contrary view and clipped my ejector spring and polished the ejector and still not reliable. So now I'm back to new springs in ejector and extractor, using silicone chrome. We see how long the ejector spring lasts. Asked CMMG to send the new h
  8. The CMMG RDB is having problems with FTE, turns out it is the ejector spring, it destroys them in less than 1000 rounds. Drift over AR15.COM . CMMG will send you a heavy ejector spring, as for a new roll pin because it will killed the one in there. Nobody knows why it Kills springs
  9. I've worked on a blue and stainless 692 6" I like them timing on cylinders is great nice early lock, the stainless is magnetic and must have fair amount of steel, it machines and polishes nicely. Lot more gun for the money than S&W.
  10. That's why I bought a Taurus 692 for half the price and in my opinion it is a better gun
  11. I got to shoot one and inspect it. Amazing difference, totally changes the recoil impulse. If I get chance we've got the mantis we will plot old vs new. Greatly lessened the time, used be three parts, ignition, bottoming buffer and bolt closing. With reduced math that last two parts are virtually gone.
  12. Thanks for the comments, I find your products very helpful
