I was considering using some HNBR O-rings on some of the dynamic o-rings (ram, poppit, lpr/hpr pistons, bolt O-rings). The Durometer and sizes would be the same. Has anyone tried this or think I may have any issues? I have experimented with O-rings in the past with good results on spool valve guns and played around a little bit with O-rings on the bolt of my G6R as well. They are not much of a difference in cost and I figure they should last a bit longer than Buna.
