Savage Flux and RPM arms: A warning

[Bondonutz]

If I remember correctly, I seen something in the directions years back about "trimming may be nessasary for perfect fit "
Bottom line I'm not complaining, I'd much rather have to much than to little. You'd be better off trimming a little material off rather adding a washer or spacer for slop free fit.
Maybe the molds wear after so many pour and releases ?
