More data points for guard owners.
Suppressed 8" 45 appears to jar top round in magazine forward ONLY when not using 2oz carrier weight (stock 3.7 buffer)
Unsurpressed 8" 45 still ejects and cycles quick and soft while using 2oz carrier weight (stock 3.7 buffer)
Suppressed 5" 9mm ejects brass into deflector HARD even with 3.5oz carrier weight.
Today, CMMG informed me they ship 5" Banshee model with AR10 spring and gutted .9oz buffer.
Personally noticed carrier return speed much higher than 45, bolt closing HARD.
My next step is swap in the lighter AR15 spring and/or heavier buffer to compare ejection.
