All, I just spoke with Joe Logie at champion and he asked me to tell VAFers that the SB has an error with regards to the return instructions. For impulse coupled mags remove the gear only. Leave the impulse coupler on and just put the castle nut back on hand tight.
Also, yes the repair is free for all within the S/N range specified in the SB.
He said the current turnaround time is closer to 3 weeks now. This SB affected about 100,000 mags and they sometimes come in from a few hundred a week to a thousand or more.
