I wouldnt have thought so - it is not as critical as say a hammer spring or main spring is say a springer re rotation and loads are very low so no wear issues. Not sure of the R10 trigger set up as never had one, but most sit in a recess and issues re rotation are not high.
Worth a try for say under a £5 incl postage. etc
